ThesisItem Open Access Assessment of nutritional status of pregnant women with special reference to anaemia and obesity in district Hisar ( Haryana)(CCSHAU, 2016) Sethi, Divya; Dahiya, SarojThe present study was conducted in Hisar district of Haryana state to assess the nutritional status of pregnant women and impart nutrition education to the selected pregnant women. A total of 250 subjects having pregnancy of third trimester selected randomly from different hospitals of district Hisar. Respondents from both govt. and private hospitals selected so as to draw a sample of both urban and rural women.Nutritional status of pregnant women was assessed in terms of dietary assessment, anthropometric measurement (height, weight and skin fold thickness) and clinical assessment of signs and symptoms of various nutrient deficiency diseases. Dietary assessment was done by 24 hour dietary recall method for three consecutive days of 100 respondents. The results of the study revealed that consumption of all food stuffs like cereals, pulses etc were lower in the diets of pregnant women. Nutrients like energy, fat, β- carotene, B-complex vitamins, Vitamin C, Iron and Calcium were found limiting in the diets of pregnant women. It was found that caste, family size, income, working status and education of respondents and husband‘s education had significant (P<0.05) effect on food intake of selected pregnant women. Effect of caste, family size,family type, income, respondent‘s occupation and education, husband‘s occupation and education were found to be significant (P<0.05) on nutrient intake of the pregnant women. Result indicated that out of 250 pregnant women 79.2 per cent pregnant women were anaemic while 20.8 per cent were non anaemic. Effect of type of family and income were significant (P < 0.05) on prevalence of anaemia. Majority 47.2% women were overweight, 25.2 percent obese, 22.8 percent normal weight and 4.8 percent underweight.Nutrition education was imparted to 50 selected pregnant women. It was found that majority of the responents had inadequate knowledge regarding nutrition before imparting nutrition education. After imparting nutritional education there was significant (P<0.01) improvement in knowledge of pregnant women in all the characteristics.ThesisItem Open Access Nutritional evaluation and utilization of okara (Soybean milk residue) for developing probiotic fermented food products(2016) Suman; Khetarpaul, NeelamThe present study was carried out with the objectives to develop naturally and probiotic (Lactobacillus acidophilus) fermented okara based food products, to evaluate sensory characteristics, nutrient composition and shelf life of developed products. The study revealed that soaking of soybean seeds significantly (P<0.05) increased the grain dimensions and diameters while decreased the sphericity.The water absorption and swelling capacity were significantly higher, whereas, oil absorption capacity and bulk density of okara were lower as compared to those of soybean. Okara had 24.79 g protein, 10.52 g fat and 19.83 g crude fibre per 100 g. The total, soluble and insoluble dietary fibre contents of okara were 58.21, 11.57 and 46.64 g/100 g, respectively. Okara had lower phytic acid content and higher in vitro protein digestibility as compared to soybean. Okara contained good amount of minerals, higher mineral availability and antioxidant activity. A significant (P<0.05) decrease in pH with corresponding increase in titratable acidity occurred when okara slurries were fermented naturally and with L. acidophilus probiotic curd (108 cells/ml) for varying time periods as compared to raw okara. Microbial cell counts of okara increased with the increase in period of fermentation. The fat, crude fibre, total and insoluble dietary fibre and phytic acid contents of okara decreased significantly (p<0.05), whereas, soluble dietary fibre, availability of minerals, in vitro protein digestibility, total phenolic and DPPH free radical scavenging activity of okara improved significantly after natural and probiotic fermentation over unfermented raw okara control. Among the various naturally and probiotic fermented food products developed idli and dhokla prepared by incorporating 10% okara powder and wadi and rabadi containing 20% okara powder were found to be organoleptically most acceptable. Probiotic banana yoghurt containing 2.5 g okara powder had higher organoleptic scores than those containing 5 and 10 g okara powder. Naturally and probiotic fermented idlis containing 10 per cent okara powder had the lowest hardness. Hardness of both naturally and probiotic fermented dhokla increased whereas that of wadi decreased as the level of okara powder supplementation increased from 10 to 30 per cent. Microbial count of all the products increased at the end of fermentation. Supplementation of 10 per cent okara powder in idli and dhokla and 20 per cent okara powder in rabadi and wadi improved the protein, fat, crude fibre, dietary fibres, total minerals and antioxidant activity. On the other hand, in vitro protein digestibility and available mineral contents were significantly lower and phytic acid contents were higher in okara supplemented products than those of fermented products without okara. Fermented instant mix powders of idli, dhokla and rabadi were organoleptically acceptable when stored for three months. Lactobacilli counts of instant mix powders were within the minimum requirement limit for probiotic activity during storage.ThesisItem Open Access Development and evaluation of malted sorghum based weaning foods(CCSHAU, 2016) Varsha Kumari; Sindhu, Sangeeta ChahalIn the present study, malted sorghum based composite flours were developed using blanched mungbean/soybean flours and blanched banana flour.

Total lysine content varied from 5.50-6.88 g/16g N. In sorghum-soybean-banana composite flours, the moisture content varied from 3.70-4.38 per cent; crude protein varied from 15.52-18.50 per cent; crude fat varied from 3.45-5.31 per cent; crude fibre varied from 2.08-4.04 per cent; ash varied from 2.39-2.52 per cent; total carbohydrate varied from 70.78-76.56 per cent and energy content varied from 399.37-403.29 Kcal. Total soluble sugars varied from 1.51-4.15 per cent; reducing sugars varied from 0.86-1.10 per cent; non reducing sugars varied from 0.68-3.05 per cent and starch varied from 23.86-28.04 per cent. The in vitro protein digestibility varied from 34.53-36.03 per cent, while the starch digestibility varied from 26.61-38.56 mg maltose released/g. The per cent extractability varied from 70.29-79.33 per cent for phosphorus; 77.97-83.38 per cent for calcium; 75.02-81.83 per cent for iron and 73.70-77.31 per cent for zinc. Total lysine ranged from 6.45-9.32 g/16g N.The developed composite flours were found to be acceptable to judges during the storage period of 60 days with total microbial count ranging from 5.2×10 3 to 9.9×10 3 cfu/g .To study the effect of sorghum malt, composite flours of similar composition incorporating unprocessed sorghum were simultaneously evaluated. Incorporation of malted sorghum flour resulted in reduced bulk density and water absorption capacity in all the composite flours. It brought significant reduction in moisture, protein and fat content of all the composite flours. A non significant increase was observed in crude fibre content. The ash content also depicted a non significant decrease (p≤0.05).A significant (p≤0.05) increase in total soluble sugars, reducing sugars and non-reducing sugars along with a significant (p≤0.05) decrease in starch content was observed. It significantly (p≤0.05) improved the in vitro protein as well as starch digestibility. Though no significant changes were observed in total mineral content for phosphorus, calcium, iron and zinc; the extractability improved significantly (p≤0.05).The developed composite flours were used as base to develop weaning foods. It was found that 80 g of either skim milk powder/whole milk powder and 48 g of sugar per hundred gram of each of composite flour when cooked in 800 ml of water resulted in weaning foods of acceptable consistency and taste. The weaning foods thus obtained were found to be acceptable to judges. On the basis of mean scores of sensory evaluation obtained, two weaning foods, one each incorporating mungbean and soybean were selected for further analysis and coded as SMBWF (sorghum-mungbean banana-weaning food) and SSBWF (sorghum-soybean banana-weaning food). Both SMBWF and SSBWF were found to be acceptable to lactating mothers with a good nutrient profile.ThesisItem Open Access Utilization of amaranth seeds for development of products(CCSHAU, 2016) Akanksha Singh; Punia, DarshanThe present investigation was carried out to analyze the physic-chemical properties and nutritional composition of maranth and their utilization for product development. The products prepared using amaranth included chapatti, porridge, ladoo, sev and kheer. The developed products were evaluated for sensory and nutritional parameters.The results on physico-chemical properties of amaranth revealed that bulk density of amaranth was 6.06g/ml, water absorption capacity 9.40 ml/g and fat absorption capacity 58.16%. Swelling capacity of amaranth was 2.54 ml/g.The results of proximate composition revealed that Amaranth had moisture 10.33%. 14.29% protein, 5.80% fat, 2.84% ash and 4.91% crude fibre. Albumin, globulin, prolamin and glutelin fractions of amaranth were 9.82, 9.50, 1.42 and 1.28 per cent, respectively. The total, soluble and insoluble dietary fibre content of amaranth was 27.34, 9.40 and 17.95%, respectively. Calcium, zinc, iron and potassium contents were 272.03 mg/100g, 5.81 mg/100g, 13.76 mg/100g and 329.87 mg/100g, respectively. Five products namely chapatti, porridge, ladoo, sev and kheer were prepared using amaranth and were evaluated organoleptically using nine point Hedonic scale by a panel of ten judges. Mean scores of organoleptic parameters indicated that all the products were acceptable in terms of their colour, appearance, aroma, texture and taste. Overall acceptability scores of the five products revealed that chapatti, salty porridge, sev, ladoo and kheer were “liked moderately” and sweet porridge was „liked very much‟ by the judges. Sensory evaluation of products showed that amaranth could be incorporated up to 60% in chapatti and 40% in ladoo, 50% in porridge and sev and 100% in kheer. Results of the study on Proximate composition of products showed that after incorporation of different levels of amaranth in chapatti, porridge and kheer, the content of crude protein, fat, and crude fibre increased significantly. It was observed that addition of 20% amaranth flour to wheat flour (Type I chapatti) did not bring any change in its ash content, whereas addition of 40% (Type II) and 60% (Type III) amaranth flour significantly increased ash content from 1.58 (control chapatti) to 1.75 and 1.81%, respectively. With the increase in the level of amaranth in porridge and kheer, ash content increased significantly. The results of the study indicated that with the increase in incorporation level of amaranth flour in various products the amount of total dietary fibre, insoluble and soluble dietary fibre increased significantly. In the present study, the mineral determinations revealed the presence of good amount of essential minerals like calcium, zinc, iron and potassium in the formulated products. It was found that all minerals studied increased to a significant extent after incorporation of amaranth flour to various products.ThesisItem Open Access Development of baked products using wheat-soybean flour blends and pomegranate peel powder(CCSHAU, 2016) Tharshini, Ganeshan; Sangwan, VeenuThe present study delineates information pertaining to the nutritional evaluation of wheat variety (WH-1142), soybean flour and pomegranate peel powder and development, nutritional evaluation and study of shelf life of cake, bread, cookies and nankhatai prepared using wheat and soybean flour blends and pomegranate peel powder.
