Publisher: 2012Dissertation note: Major portion of the poultry feed is composed of cereals and vegetable proteins, which cannot be fully digested and utilized by poultry due to lack of endogenous enzymes. However, it can be increased by use of exogenous enzymes. The major cost in the raising of poultry is feed. Utilization of most grains is influenced by the presence of indigestible complex carbohydrates, such as non-starch polysaccharides (NSP's) in poultry. It is possible to partially degrade these NSP's with selective exogenous enzymes acting on specific raw materials, e.g., in spite of having more gross energy in soybean meal than corn, its metabolizeable energy is less than that of corn because of -galactosides (raffinose and stachyose) that can not be digested in small intestine of broilers but these can be hydrolyzed by exogenous enzymes. Addition of organic acids in the feed has shown positive response in growth performance as they are bactericidal and reduce the incidence of Salmonellae in crop and carcass. Furthermore, organic acids are used in feed to get the favorable level of pH for the action of exogenous enzyme -galactosidase .Keeping in view the importance of supplementation of exogenous NSPs enzymes and organic acids, a 35 days trial was conducted in broiler chicks (n=240) by dividing them into eight groups and each group was having three replicates with 10 birds in each. Control group was fed NRC (1994) recommended diet (Diet A). Diet B was formulated with low metabolizeable energy (2630 Kcal/Kg). Diets C, D was formulated by adding two different levels( 0.25 gm/Kg feed and 0.5 gm/Kg feed) of NSP digesting multiezyme "Zympex" in diet B and diets E, F with different levels (0.5% and 1.5%) of citric acid in Diet B. While diets G, H was formulated by adding above mentioned different level of enzyme and citric acid in Diet B.
The weekly weight gain results showed that broilers of basal diet attained maximum weight gain which was followed by low energy diet having 500g/ton zympex, low energy diet having 500g/ton zympex plus 1.5% citric acid, low energy diet having 250g/ton zympex plus 0.5% citric acid, low energy diet with 250gm/ton zympex, low energy diet, low energy diet having 250gm/ton zympex plus 0.5% citric acid and low energy diet having 500gm/ton zympex plus 1.5% citric acid respectively. The differences of average weights of various groups when compared statistically with group A, revealed that the weights of group B, C, E, F, G and H were significantly different (p<0.05) whereas, the differences of group A and D were found non significant. While comparison of various groups with B revealed that the weight of group A, D, G and H are significantly different with B, but groups C, E and F are non significant with B. Groups B and C, C and G, B E and F, A and D, G and H are non significant among each other . On comparison of various groups with group D it was found that weights of group B, C, E, F, G and H were significantly different (p<0.05). It is evident from the above results that there is increase in weight of broilers of group D, showing non significant difference from control group A, supplemented with enzyme complex.
The results showed that maximum feed consumption was by group B followed by group C, A, D, G, E, H and F. The data of feed consumption when put to analysis of variance showed significant difference (p<0.05) of group A, B, C, D, E and G with F and H while the feed consumption of group F and H was found insignificantly different from each other. When comparison of various groups was made with feed consumption of group A, the feed consumptions of group B, C, D, E, F, G and H were found significantly different(p<0.05). While Comparison of various groups with B showed significant difference in feed consumption with all other groups.
The overall FCR of group A was found to be the best among all groups, which was followed by group D, H, G, F, C, E, and B. The analysis of variance among different experimental groups showed a significant difference (p<0.05) when groups B, C, E, F, G and H was compared with A, while D was insignificant with A. While comparing B with all groups showed significant difference with all groups. Group D and H are non significant with each other which indicate that FCR is better in D followed by H among treatment groups which is very near to control group A, showing activity of enzyme complex and acid.
The results show the values of glucose level at different time intervals, before feeding the glucose level in groups A, B, C, D, E, F, G and H showed significant results. When the data of glucose was subjected to ANOVA it revealed that group C, D, E, F, G and H were significantly different with A. Group C, D, G and H showed significant difference with B. Group B, E and F were non significant among each other. Group A showed significant different with all groups. The data obtained 1 hour after feeding when subjected to analysis of variance when compared with group A showed that groups B, D, E, F, G and H were significantly different with A. Group A, C, D, F, G and H showed significant difference with B. Group H was significantly higher among all. Data recorded after 2 hour when subjected to ANOVA revealed significant difference of group C, D, G and H with group A and B. Groups A, B, E and F are insignificant among each other. While group is significantly different with all groups. Values of data collected after 3 hours of feeding when subjected to analysis of variance showed significant difference of groups B, C, D, E, G and H with A. Groups A, C, D, G and H were significantly different with B. Group B and F were non significant among each other. Glucose level was higher in H followed by D, G, C, A, F, C and E.
The data calculated for ME when subjected to ANOVA it reveals that groups E and F are significantly different with other groups and shows non significant difference among each other. Other groups A, B, C, D, G and H are showing no significant among each other. ME in groups D and G is equal to control group A which shows the action of enzyme or acid which results in more release of energy.

; Nature of contents: ; Literary form: Publisher: 2012Dissertation note: Anemia is abnormal condition in which there is drop in the number of red blood cells or the heamoglobin in them to lower than the normal blood cells and consequently there is less supply of oxygen to body and it gets less energy as compared to it needs for performing normal function (Bunnet al., 1995).The concentration of haemoglobin fluctuates with various factors that involves age, physiological condition, sex and person altitude from sea level below its normal value that is 14g/dL When iron that is absorbed from diet is unable to meet physiological related requirements of the body it leads to nutritional iron deficiency. Locally prepared iron fortified pasteurized milk may be helpful in increasing the haemoglobin status of anaemic patients in the same way as iron supplements.
Therefore present project was designed for preparation and characterization of iron fortified milk and its utilization against iron deficiency anemia. In first part of the study Iron fortified milk was prepared by adding different concentrations of iron sulphate (FeSO4) @ 0.00 (as a control), 0.04, 0.06 & 0.08%. In second part sensory evaluation and physicochemical analysis of iron fortified milk samples were performed. During the third part of the study, efficacy of iron fortified pasteurized milk was evaluated in Sprague Dawley Rats.Accordingly the significant outcomes of the present research are summarized hereafter.
Proximate analysis showed that the milk prepared from different level of iron are non-significant for fat content as well as for storage intervals (P?0.05) and also the interaction between treatment and storage level also showed non-significant effect.
The result for protein of milk fortified by iron at different levels is showed that they are statistically non significant (P?0.05). The storage of these treatments and the interaction between the treatments and storage intervals also showed non-significant effect on protein of different treatments.
Analysis of variance for SNF for different treatments of milk shows that they are statistically non significant (P?0.05).Data regarding mean values for storage study of SNF of different treatments showed that the mean values for control milk are 8.21 and there is no increase significantly with iron fortification at 0.04, 0.06 and 0.08% which showed 8.73, 8.66 and 8.82 respectively. As the storage progressed the SNF content not differ significantly from 8.50 to 8.81 at 0 and 4day respectively.
The statistical analysis regarding pH for milk fortified by iron at different levels showed that analysis of variance for pH of different treatments of milk, storage shows that they are statistically highly significant (P? 0.01) and the interaction between the treatments and storage intervals showed slightly significant effect on pH of different treatments
The statistical analysis pertaining to Total Solids for milk fortified by iron at different levels, storage and the interaction between the treatments and storage intervals also showed that they are statistically non significant (P?0.05).
The results for Vitamin C content showed that the values for different treatments for fortification of iron are highly significant (p?0.01).Mean values for storage study of vitamin C different treatments showed that the mean values for control milk are 4.50 and increases significantly with iron fortification at 0.04, 0.06 and 0.08% which is 25.68, 26.01 and 25.26 respectively. As the storage progressed the Vitamin C content decreases significantly from 22.7 to18.5 at 0 and 4day respectively. The interaction between treatment and storage level showed non-significant effect on Vitamin C of iron fortified milk (P?0.05)
Using statistical design for mineral Iron of different treatments of milk showed that the fortification of Iron at different levels in milk has significant effect (p?0.001).The results of Mean comparison of Fe showed that control has lowest score (0.06±0.00) and 0.06% and 0.08% had highest scores that is (0.11±0.001) and (0.155±0.001) respectively
The statistical analysis pertaining to flavor for milk fortified by iron at different levels , their storage for four days at 4°C and the interaction between the treatments and storage intervals showed that they are statistically non significant (P ?0.05).
The statistical analysis pertaining to sensory attributes of iron fortified milk prepared at different levels of FeSO4 and control for taste , colour , flavor, consistency and overall acceptability, their storage for four days at 4°C refrigeration temperature and the interaction between the treatments and storage intervals showed that they are statistically non significant (P?0.05).The statistical analysis pertaining to haemoglobin level w.r.t to groups of rats and study intervals is highly significant (P?0.01) The interaction between different groups and study intervals also showed highly significant (P?0.01) results. For haemotological measurements statistical analysis showed that mean data regarding Group A showed haemoglobin level at 0 day (9.68±0.435)g/dL which increase slightly at 14 and 28 day and then again decrease at 56 day (9.34±0.171) g/dL.

Publisher: 2012Dissertation note: Omega-3 polyunsaturated fatty acids which include linolenic acid, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) might reduce risk factors for heart disease through lowering total blood cholesterol, LDL, blood pressure, triglycerides and enhancing the level of blood HDL. Excellent sources of omega-3 fatty acids are fish, flax seed, olive oil etc. Recently the efforts had been successful to bio-fortify or improve the omeg-3 fatty acid contents of the products like eggs through feed manipulation. However, the information was lacking on extent of subsequent health benefits of such bio-fortified/ designer products. For the purpose, this project had been designed to test the efficacy of omega-3 enriched eggs against hyperlipidemia in hypercholesterolemia adult human subjects.
Omega-3 polyunsaturated fatty acid bio-fortified eggs improved the lipid profile in hypercholesterolemia humans. Omega-3 polyunsaturated fatty acids eggs (more than 200mg per egg); already bio-fortified through feeding management, were obtained from University of Sargodha. The eggs were analyzed for chemical composition; protein, carbohydrates, ash, fatty acids, cholesterol content and physical parameters color, weight, volume, density etc. Representative samples from bio-fortified lots and control eggs were boiled and evaluated for organoleptic acceptability through a 10-member panel of trained judges for parameters of taste, texture, flavor and overall acceptability. Finally, representative samples of bio-fortified and control eggs were used for efficacy studies against hypercholesterolemia in human subjects. Twenty- two hypercholesterolemia adult subjects with both sexes without complications were recruited after informed consent, divided into two groups having 11 in each group. We selected those patients whom cholesterol level was > 200mg/dl, triglycerides level also greater than 200 mg/dl, normal blood pressure and no heart problem. First group was provided with bio-fortified eggs whereas second group was not provided either of the eggs. The individuals in 1st group were asked to eat one egg per day in morning until 40 days whereas the individuals in 2nd group were advised to continue with their usual diets. The blood samples of the individuals were obtained at the start of the study, after this blood sample was obtained only weekly basis for 40 days. The blood was analyzed for blood lipid profile to assess the impact of omega-3 bio-fortified eggs against various blood lipid fractions.
The data thus collected was analyzed statistically to check significance (Steel et al., 1997). Means were compared for significant difference with t-test for physical and chemical composition parameters and with Least Significant Difference (Duncan, 1955) for efficacy studies.

Publisher: 2012Dissertation note: Wheat is one of the popular cereals that supply the basic nutritional and energy requirements of the population. More so, wheat flour is commonly consumed across the world. Complementation of wheat flour with Indian vetch will not only upgrade its protein quality but also will helpful in decreasing glycemic index because studies have shown effects of Indian vetch on glycemic index. Objectives of the present study are to develop low glycemic, nutritious composite flours and to assess the glycemic efficacy of selected composite flour based chapattisin normal adult human subjects.
The present study was conducted in two phases. During first phase composite flours were prepared and their chemical, functional and rheological properties were analyzed. In second phase the effect of sample chapattis on post- prandial glycemic response in healthy subjects was evaluated.
The composite flours were prepared by mixing various ratios of wheat flour and Indian vetch flour. The ratio of Indian vetch flour was 10, 20, and 30 g respectively with 90, 80, and 70g wheat flour. Chemical properties revealed that The results for the proximate composition of composite flour and wheat flour show that the moisture content of composite flours is lower than the wheat flour , which progressively decreased as the level of Indian vetch supplementation increased. The supplementation at different levels of Indian vetch flour (seed coat removed during milling) has a significant lowering effect on the crude fiber, ash and crude fat but a significant increase was observed in the protein content, which was due to high protein content of Indian vetch flour.
Mean square for bulk density of composite flour blends shows that bulk density was significantly affected by the Indian vetch flour addition (10-30Overall, bulk density ranged from 86.66±1.527 to 83.66±1.154 in all flour blends.
Water and oil absorption capacities are amongst the important functional properties for additives supplemented in food systems. Water and oil absorption are significantly affected with addition of Indian vetch). 30% Indian vetch Composite flour showed excellent water holding capacity 5.889±0.040% as compared to wheat flour 4.956±0.056%. The oil absorption capacity of composite flour was noted to be 5.64±0.032% that was significantly higher than that of wheat flour (T0). Therefore water and oil absorption capacities of flour blends were improved at all levels of Indian vetch flour addition.
Foaming capacity and stability were also significantly affected among different compositions of flours. T30 flour sample showed foaming capacity 9±0% and foaming stability 8.5±0%, whilst T0 wheat flour possessed 7.166±0.288% and 6.51±0.5% of foaming capacity and stability, respectively. The foaming stability of composite flours increased as the ratio of Indian vetch increased in present study. As expected, Indian vetch flour addition resulted a significant increase in the stability of foam in flour blends.
Gelling power of the flour dispersions increased with the level of Indian Vetch flour in flour blends. The highest gelling power was observed in T30 (30% Indian vetch flour). The partial gelation in T20 was observed at 4% flour suspension, whereas in T30 above 3% flour dispersion resulted in complete gelling. The lowest gelling properties were noticed in case of T0 (100% wheat flour).
It is evident from results that Indian vetch addition resulted in decreased redness ("a") and increased lightness ("L") . Hunter color values increased significantly with Indian vetch addition in composite flour , representing an increased yellowness of chapatti . The values for Chroma remained same while hue angle also increased momentously by adding up of Indian vetch.
Dough rheological behavior is mainly affected due to protein quantity and quality of flour. The rheological characteristics are the source for understanding the dough handling behavior in bakery. Consequently, dough properties play a key role in quality of finished products. Significant variations were observed among various flour samples for these traits.
On the basis of sensory evaluation two best chapatti samples T10 and T20 were selected for further efficacy studies.
A total of 10 healthy adult volunteers were recruited through flyers, emails and personal contacts. Eligibility for volunteers will be determined on the basis of age (20-50 years), health status, individuals having optimum BMI and free from any communicable diseases and gluten allergy. The study procedure was discussed with all volunteers and were asked to sign the consent to voluntarily participate in the study.
Predicted glycemic index was lower in chapattis added with 20% Indian vetch flour than in 10% composite flour and 100% wheat flour. So chapattis of composite flour might be a dietetic alternative forpeople with low-calorie requirements.

Publisher: 2013Dissertation note: Functional food does not only provide nutrition but works as defense against human nutrition related diseases (Menrad et al, 2000). Global market of functional foods industry has worth at least 33 billion US$ (Hilliam, 2000). Functional foods are the foods that provide health gains and can reduce the risk of diseases beside basic nutrition, including health care of gut. The first generation of functional foods involved supplementation of calcium (Ca) and vitamins for their recognized health attributes (Saarela et al, 2002). Among these additives, probiotics and prebiotics have acquired more interest as a major group of functional food additives (Gibson and Ziemer, 1998).
GOS present in commercial milk powder has the ability to promote the growth of bifidobacterium and lactobacilli in vitro reported by the studies (Cummings et al, 2001; Cummings, 1995).The market of GOS in infant formulae milk as a food ingredient and due to its bifidogenic properties is gaining popularity (Chow, 2002). GOS are chiefly used in infant milk formula and infant foods (Crittenden and Playne, 2009). Their remarkable thermostable properties allow them to be incorporated in large variety of foods and commercial products in addition to infant foods (Yang and Silva, 1995). Recently, they have been used in beverages (fruit juices and other acid drinks), meal replacers, fermented milks, flavored milks, and confectionery products (Affertsholt-Allen, 2007).
Laboratory scale reactions for GOS synthesis were carried out by dissolving 600mM lactose solution in phosphate buffer (0.1 M, pH: 6.8) to which £]-galactosidase at varying levels was added. As indicated by studies in the literature (Kim, 1997; Barbara et al, 2006; Playne et al, 2009), high lactose concentrations facilitate transglycosylation reactions.
Milk was procured from local market and concentrated for 15 min and milk was stored at refrigeration temp for further analysis. 5ml of milk samples was taken for enzyme analysis 0£gl, 100£gl, 200£gl, 300£gl and 800£gl respectively samples was collected at 30min
_____________________________________________________________SUMMARY

Publisher: 2013Dissertation note: Tea whitener is now become a popular trend in Pakistan with 01 billion tons consumption annually according to my personal information and its consumption is increasing day by day. The replacement of hydrogenated palm oil used traditionally is necessary as they contains 49.3% saturated fatty acids, the majority of which are palmitic acid, myristic acid and lauric acid which are proved to be most injurious for human health, raises the total and LDL cholesterol (Bonanome et. Al, 1998). Canola oil is known for its low level of saturated fatty acids, a relatively high level of monounsaturated fatty acids, and a very good amount of the n-3 fatty acid a-linolenic acid. Canola oil consists of an appreciable amount of a-linolenic acid which amounts for almost 10 percent which is a fairly good quantity. In addition, 1:2 is the ratio balance between linolenicacid and linoleic acid which is favorable and well balanced. Canola oil is a relatively rich source of tocopherols,60-70 mg/100g, contains high level of phytosterols (892 mg/100 g. Keeping in mind the above mentioned nutritional aspects, canola oil based tea whitener is developed.
The research was conducted in two phases. During 1stphase the HLB requirement of the canola oil and partially hydrogenated palm oil was determined which are determined as 08 and 06 respectively. Then the emulsifier's percentages are calculated according to their standard HLB values and the doses of the emulsifiers "DATEM" and "GMS" are adjusted according to the ratios of hydrogenated palm oil and canola oil in all the formulations. During second phase the proximate, chemical, physical and sensory analysis are done for all the emulsions so as to determine their resemblance with the control formulation S1.
Different graph analysis regarding proximate analysis of canola oil based tea whitener showed that the results for moisture percentage are (85.69 ± 0.089), for crude protein the values are (1.66±0.22), for dry matter its (14.32±0.04) for crude fat the result shows (7.01±0.03). The variation in all the emulsions were negligible, as the ingredients except fat source is almost the same in all the formulations.
The results for acidity of tea whitener emulsions on the 2nd day which is 0.09± 0.02 which shows the acceptable range, while on the 6th day the mean value of the acidity is also in the acceptable range which is 0.14± 0.01 which means acidity increases to some extent on the 6th day of storage. The mean of the acidity on the 8th day is 0.16± 0.01. The trend shows the acidity increases from 0.09±0.02 to 0.16±0.01 in 08 days. The variation was observed in all the emulsions with the passage of time, but there is not a very significant difference among all the emulsions as compared to control S1.
Mean values for pH on the 2nd day is 6.79±0.03 while the control sample S1 has the pH value of 6.82 on the 2nd day and the treatment which has the lowest pH values on day 2nd is S6 with pH 6.75. The observations on 6th days are shown in pH chart which shows slight decrease in pH in the 6th day with the mean value 6.71±0.02. The mean value of pH on the 8th day is 6.61±0.02. The results showed that pH of tea whitener emulsionsdecreases as storage progressed. A very interesting point raised during study that the pH values of the standard emulsion S1 is higher among all the emulsions on the 2nd day, but as the days proceeds, the pH of the emulsions with different rations of canola oil retains their pH and the pH becomes almost the same as standard on the 8th day. This may concludes that the emulsions containing canola oil retains their ph more as compared to palm oil based emulsion.
The mean value of density of the tea whitener emulsions 1.12±0.02. So overall the results variation is not significant. The little difference may be due to the fact that palm oil has density of 0.89 L/kg at 25 C while the density if canola oil is 0.91 L/kg on the same temperature. The density of all the formulations are comparable with the control emulsion S1.
The results depicted that 'L" value was decreaseswith increase in the ratio of canola oil. Mean comparison for color "L" parameter showed that highest value for S1 which is 90.45 and least value for S8 which is 89.29. The variation is very slight but the palm oil based emulsions are slight whiter in the appearance.The mean value of a* is -0.285 ± 0.095 which shows a very little variation. The level of greenness decreases slightly as the ratio of the canola oil increases from S1 to S8. The degree of yellowness in the emulsion increases as the ratio of canola oil in increases in the emulsions. The mean value of b* is 2.94±0.27 which shows a slight variation as we go from S1 to S8.
The sensory attributes scores obtained from sensory evaluation by trained panelists varies a lot. Addition of canola oil in place of palm oil significantly alters the flavor, After taste and over all acceptability of the tea made with tea whitener emulsions from S1 to S8, the scores are almost the same up to S4 as compared to control formulation S1 for all the attributes mentioned above. Score decreases from S5 to S8 which is definitely due to the addition of canola oil in the formulations. The sensory attributes like fat separation and color get the same scored almost for all the formulations.
Flavor scores are almost the same up to S5 but the scores decreases significantly from S6 to S8, for the sensory attribute of "after taste" the formulations from S1 (standard) to S4 get good scores means the after taste if the S2, S3 and S4 are comparable to the control emulsion S1 while S5 to S8 get lower scores, For "overall acceptability" S2, S3 and S4 are nearly equivalent and good scores as compared to control formulation with 100 percent palm oil formulation with the mean value of 90±02 which gives a green signal that we can partially replace hydrogenated palm oil with canola oil. The formulation S5 get a little lower score as compared to control one. The formulations from S6 to S8 get lower scores in overall acceptability.
Finally it is concluded that the formulation S4 is the one which can be replaced with the control emulsion S1 for making of tea which means 42.5 percent of the total fat in tea whitener can be replaced successfully with canola oil without compromising the physical, chemical and sensory properties of the tea.
Recommendations
The main aim of this project was to make a tea whitener which is based on healthier and heart friendly oil (canola oil) instead of palm oil. Canola oil has been used as a cooking oil and also in nutritional products like "Ensure Plus" and "Glucerna" due to its health friendly composition. The idea is drawn from the nutritional products compositions whose fat part is mostly consists of canola oil.
In Pakistan, keeping in mind a very huge consumption of tea whitener of 01 billion annually according to my personal information. The production may be much higher as my information may be limited. Keeping in mind the annual production or consumption of liquid tea whitener in Pakistan, the delivery of more healthy oil to the consumers by incorporating it in the liquid tea whitener product seems to be a pretty good idea. It is not only the matter of incorporation of healthy canola oil but also the matter of replacement of saturated fatty acids rich palm oil. Keeping in mind the chemical, physical and sensory properties of tea whitener emulsions S4 with 42 percent canola oil of the oil phase gives similar physical, chemical and sensory properties when compared to control formulation tea whitener S1 with 100 percent palm oil as oil phase. Keeping in mind the composition of the canola oil, if tea whitener is made with 07 percent fat level, in case of S4 (The formulation with resemblance to control up to maximum canola oil extent) canola oil percentage if the total fat is 42.5 percent of the total fat, it will give 0.7 grams of omega-3 as ALA per 250 ml of the tea whitener which means that it will provide 2.8 grams of omega-3 per liter of tea whiteners which can help us to meet up to some extent the ADA recommendations which is 1.3 to 2.9 grams based on 2000 Kcal diet (ADA, 2007)
The real challenge in the making of tea whitener formulations with different ratios of canola oil and palm oil is to make a successful emulsions without fat separation, thanks to HLB system for successful making of emulsions. Another challenge is to mask the after taste of the canola oil which can be prominent in the tea whitener, the after taste of canola oil is masked by milk flavor due to which the successful replacement of palm oil with canola oil up to 42 percent becomes possible. The purpose of the product development of making it a source of omega-3 was successfully met as the results shows the partial replacement of palm oil with canola oil is possible.
From the present study it can be concluded that canola oil can be incorporated in liquid tea whitener up to the percentage of 42.5 percent of the total fat without any persistent change in chemical, physical and sensory properties of the tea whitener. The concluded value of omega-3 which it gives per 250 ml is 0.7 grams according to fatty acid profile given by ADA reports (ADA, 2007). They do not affect the taste or texture of the product. My study showed that the replacement of palm oil with canola oil up to 42.5 percent in tea whitener formulation was acceptable among consumers and also the tea whitener retained its quality and sensory properties after storage for 08 days at 04 C. The tea prepared from S4 has the same sensory properties as the tea made with the control formulation. It is recommended that canola oil based tea whitener should be a introduced in the market for creating awareness among the general population about the role of omega-3 n human health and threats of consuming saturated fatty acids. There are need of studies forefficacy of developed tea whitener whether it beneficially transmit the omega-3 to human body or not and what are the health benefits among the subjects. More research work is required to testify the product under UHT treatment to find out what are the changes in physical and chemical properties of the product up to 03 months, it's emulsion stability and it's sensory properties during and after 03 months of shelf life in tetra packaging.

Publisher: 2013Dissertation note: Lactose is milk sugar. It is found in milk and dairy products. Lactase (Betagalactosidase lactase-phlorizin hydrolase) is the enzyme present in the enterocytes of small intestinal brush border and it is responsible for the breakdown of lactose into its monosaccharide components glucose and galactose that are absorbed into the bloodstream. Lactasedeficiency leads to lactose mal-absorption and resulting gastrointestinal symptoms of intolerance.Lactose intolerance is defined by symptoms of mal-absorption such as abdominal pain,bloating, distention, flatulence and diarrhea due to partial digestion of lactose. This study was conducted in following phases. Lactose intolerance test was performed to diagnose lactose intolerance. In 1st phase lactose solution was prepared by dissolving 25grams of synthetic lactose in 250ml water and in this way 10% lactose solution was prepared and fasting blood glucose level of students was recorded first by using Glucometer. During 2nd phase lactose solution was given to each student and time was noted.During 3rd phase after giving lactose dose blood glucose level of each student was recorded at 30, 60 minutes.
Test was consider positive ifafter lactose solution dose the rise in fasting blood glucose level was less than 20mg per deciliter and if rise in fasting blood glucose level was more than 30mg per dl within 1 hour of lactose solution consumption, test was considered negative. If rise in blood glucose level was between 20 and 30mg/dl then on the basis of sign and symptoms of intolerance, it was decided either a person was lactose intolerant or not. According to the criteria mentioned above significant outcomes of the present research are summarized as following:
Out of 300(100.0) %, 213(71.0) % had positive lactose intolerance test and 87(29.0) % had negative lactose intolerance test.This study determined that prevalence of lactose intolerance in the UVAS, Lahore students was 71.0%. Correlation of lactose intolerance with gender, age, height, BMI, dietary food preferences was determined using chi square test and Phi Cramer's V, p value was considered significant at p <0.05. Chi square results were significant for age, height and weight. On the basis of finding of this study it can be stated that prevalence of lactose intolerance increases with increase in age, increase in weight and height.Chi square results were insignificant for gender, BMI and dietary food preferences, so prevalence of lactose intolerance is independent entity for gender, BMI and dietary food preferences.
Chi square test of independence was calculated comparing the frequency of lactose intolerance for dietary food preferences of subjects. No-significant relationship was found, X2 (2) =3.696, p = 0.158, so p >0.05. There was no correlation between the dietary food preferences of subjects and the lactose intolerance. Phi Cramer's V was used to determine strength of association between lactose intolerance anddietary food preferences of subjects.No significant relationship was found between frequencies of lactose intolerance dietary food preferences.Phi=0-.111, Cramer's V=0.111,p >0.05
There was no difference in results of the dietary food preferences of subjects and the prevalence of lactose intolerance and we can conclude that people who consumed milk products compared to those who did not consume milk/ milk products were equally affected by lactose intolerance as the non-milk product consumers and use of lactose containing milk products does not affect the prevalence of genetically inhered hypolactasia and this is in accordance with Troelsen (2005) findings, Enattah et al. (2002) findings on adult-type hypolactasia and also in accordance with Lisker et al. (1975) and Sahi et al. (1973) findings on recessive inheritance of adult type of intestinal lactase deficiency and recessive inheritance of adult-type lactose malabsorption respectively.

Publisher: 2013Dissertation note: Prebiotics are considered as selectively cultured food ingredients that impart typical improvements in the activity of the gastrointestinal micro flora that are beneficial to the host well-being and health e.g. Galacto-oligosaccharide (GOS), Fructo-oligosaccharides (FOS) and Inulin. These are different types of prebiotics used in food based product. During the last decade consideration for prebiotics in diet is getting popular due to their benefits for human health. The GOS were reported to be beneficial prebiotics for human health.
Yoghurt is a fermented milk product, which is produced by the bacterial fermentation of milk. It is a rich source of calcium, protein and vitamin B-complex. Lactose-intolerant people can eat yoghurt without any harm as lactose is converted into lactic acid by the bacterial culture. Yoghurt is more nutritive then milk and possesses better digestibility. The benefit of yoghurt depends upon the presence of beneficial viable bacterial culture in adequate number. The bacterial cultures are used in the fermentation process to metabolize the lactose, secondly the proteolysis of protein for improving bioavailability and thirdly lactic acid bacteria for production of some B-complex vitamins and vitamin K. Yoghurt culture are responsible for the production of aromatic flavor compounds.
In Pakistan manufacture of probiotic yoghurt and prebiotic yoghurt is not common and there is not consumer awareness for such kind of products. Therefore, this study was designed to develop prebiotic yoghurt from prebiotic milk and compare it with control yoghurt.
First of all milk was pastuerised and then cool to 45°C. After that ?-galactosidase was added. Transgalactosylation was carried out at 45oC with 3 hr reaction time. Enzyme was
denatured by applying heat and starter culture was inoculatedand 4-5 hours were given for fermentation.
During storage the prepared control and prebiotic yoghurt was evaluated for its physiochemical analysis and sensory qualities. Mean values of fresh yoghurt and prebiotic yoghurt are presented in tables 4.4 to 4.8 show that lactose (1.44±0.03) while for fat, protein, pH and acidity (3.43±0.15), (4.2±0.1), (4.47±0.05) and (0.92±0.01) respectively.
A panel of 10 judges evaluated the yoghurt samples for appearance, taste, color and overall acceptability on 15cm unstructured lines (15 = like extremely; 1 = dislike extremely). The sensory evaluation of the product at 0, 7, 14, 21 and 28 day was carried out in the Department of Food Science & Human Nutrition, University of Veterinary and Animal Sciences, Lahore.
Fat, pH and ash contents were continuous decreased while protein, total solid and acidity values show continuous increase in of all treatments.
All the results obtained were analyzed through Analysis of Variance Technique (ANOVA) by using Costat software.
Prebiotic milk and prebiotic yoghurt can be prepared on industrial scale because it is highly acceptable. This could be a value added product in which we can produce prebiotic economically.

Development Of Cottage Cheese Containing Prebiotic Galactooligosaccharides Through The Process of Transgalactosylation
by Muhammad Usman | Dr. Sanaullah Iqbal | Dr. Imran Javed | Prof. Dr. Anjum Khaliq.
Material type: ; Format:

Publisher: 2013Dissertation note: GOS are the prebiotics, indigestible by human, feed for the intestinal microbiota that confers the host's wellbeing and health. GOS, are prebiotics produced from the lactose through a machanistic reaction known as trans-galactosylation. GOS are generally abrevated as GOS and used to relive gastrointestinal problems including prevention of constipation, diarrhea, lowering of blood cholesterol, blood pressure, and colon cancer prevention. They have stability at pH 2 on 37°C for various months so can be fortified in non refrigerated fruit juices, while in the presence of single type of linkages ingredients have resistance in acidic medium. They are not affected on treating for 10min at 160° C pH 7, after treatment for 10min at 120°C pH 3 or for 10min at 100°C pH 2, hence have wide range of food applications. Their sweetness is 0.3 to 0.6 times the sucrose sweetness so are mildly sweet and can be utilized in very sweet food to enhance food flavors.
This study was conducted in three stages. 1st phase was the conversion of lactose, milk sugar, into GOS by the action of enzyme known as ?-galactosidase, through the process of transgalactosylation in the milk after pasteurizing the milk and was followed by heating of milk at 90 oC to denature the enzyme. 2nd stage will be preparation of cottage cheese having galacto-oligosacchrides from the prepared prebiotic milk by citric acid coagulation. 3rd phase will be consist on the physico-chemical analysis including Protein determination, Fat percentage, Moisture percentage, Glucose, Galactose, Lactose, GOS, ?-galactosidase test and sensory evaluation for the parameters i.e. appearance, taste/flavor and over all acceptability by using 9 point hedonic scale.
It was concluded that cottage cheese prepared from the milk containing prebiotics GOS also have GOS and after conducted sensory evaluation prebiotic cheese is more acceptable than cheese having no GOS.
Recommendations
Cheese is a dairy product very healthy and nutritive product as it contain casein protein, calcium and many vitamins. We produce prebiotics cheese by transgalactosylation in Pakistan. Prebiotics is non-digestible fiber contents which have beneficial effects by stimulating the growth of probiotics in colon. After having results of sensory evaluation and storage analysis it is recommended prebiotics cheese is more nutritional effects and more consumer acceptance. It must be manufactured on industrial scale.

Publisher: 2013Dissertation note: In this research work the prebiotic was prepared by using the enzyme from Kluyveromyces lactis and different doses were fed to the rats to check the growth of lactobacillus, bifidobacterium and E. coli. Firstly the enzyme activity was checked at different concentrations at different time intervals by using 20g/l lactose solution. The glucose, galactose and lactose and their mixture were used as a standard in the same concentration. After many thin layer chromatography analysis the 10µl enzyme for 45 min was enough to convert 1ml of the lactose solution.
Then, by using the same concentrations of the enzyme prebiotics galactooligosaccharides were synthesized by transgalactosylation and were fed orally to group 1 for 10 days, group 2 for 20 days and group 3 for 30 days at concentrations of 1g/day, 2g/day and 3g/day respectively. After 10, 20 and 30 days the fecal samples from all the groups were collected aseptically to check the growth of lactobacillus, bifidobacterium and E. coli. Colony counting was done to count the colonies.
In the study different doses of prebiotics GOS were given @ 1g/day, 2 g/day and 3 g/day. The plates were incubated at 37 ºC and numbers of colonies were counted on digital colony counter. The effect of different concentrations of dose of galactooligosaccharides and the effect of time duration was calculated. The P-value used was 0.05. The P-value obtained by the two way ANOVA for the effect of dose of different concentrations is 0.354521 which is more than 0.05. This value indicates that the effect of dose on lactobacillus growth is insignificant as for as the concentration is concerned. As the concentration is increased there is no effect on growth. While the other factor was the time duration i. e 10, 20 and 30 days so its effect is calculated. P-value obtained for the effect of time is 0.029958. It shows that the result is significant. As the time interval is increased the CFU/ml of lactobacillus also increased.
The consequence of different concentration of dosage of prebiotic galactooligosaccharides (GOS) and the effect of time period is determined. 0.05 P-value used. The P-value deducted by using two-way ANOVA for the effect of dose of different concentrations is 0.032328 which is less than 0.05. This value indicates that the effect of dose on bifidobacteria growth is significant. As the concentration is increased there is increasing effect on growth. While the other factor was the time duration i. e 10, 20 and 30 days so its effect is determined. P-value obtained for the effect of time is 0.014286. It shows that the result is significant. As the time interval is increased the CFU/ml of bifidobacteria also increased. The consequence of different concentration of dosage of prebiotic galactooligosaccharides (GOS) and the effect of time period is determined for E. coli. The P-value obtained 0.03984 which is less than 0.05. This value indicates that the effect of dose on E. coli growth is significant. As the concentration is increased there is increasing effect on growth. P-value obtained for the effect of time is 0.004848. It shows that the result is significant. As the time interval is increased the CFU/ml of bifidobacteria also increased.
