Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Comparative study on nutritional composition of raw and germinated quinoa (chenopodium quinoa) flour and development of ready-to-eat (RTE) snack
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-09) M. Anuhya; Dobhal, Neetu
    Quinoa (Chenopodium Willd.) is a gluten-free nutrient-dense pseudocereal. In the present study, quinoa was germinated to observe its effect on physical and functional properties, nutritional and antinutritional content and total antioxidant activity. The results showed that germinated quinoa possessed good functional properties like water absorption capacity, oil absorption capacity, emulsion capacity and stability, foaming capacity and foam stability, which are beneficial in product development. Proximate analysis revealed that the crude protein and crude fiber content of germinated quinoa flour (13.6 and 7.16%) was higher than raw quinoa flour (13.4 and 4.01%). Moisture, total ash, crude fat and carbohydrate content of raw quinoa flour (11.01, 2.22, 5.2, and 64.15%) was higher than germinated quinoa flour (9.03, 1.55, 4.3 and 64.34%). Data on mineral composition revealed that germination of quinoa led to significant increase of 49, 33.87, 18.38 and 13% in iron, calcium, potassium and phosphorus, respectively. Dietary fiber and in-vitro protein digestibility of germinated quinoa flour was significantly higher than raw quinoa flour. The findings showed that all antinutritional factors decreased significantly on germination while antioxidant activity increased. Among the different combinations of whole wheat flour and quinoa flour for developing waffles, the waffles developed with 100% raw quinoa flour and 60% germinated quinoa flour were found most acceptable on the basis of sensory evaluation. One serving of 100% raw quinoa flour waffles and 60% germinated quinoa flour waffles provided around 9-13 % of RDA of energy and 17-26 % of RDA of protein for children of age 7-12 years. Therefore, it can be concluded that this nutrient-dense snack can be considered a healthy alternative in the fast changing world, where lifestyle disorders, especially in the children are becoming a major problem

    Study on nutrition and health related practices of schools in association with nutritional status and knowledge of early adolescents in Dehradun district
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-04) Belwal, Ekta; Kushwaha, Archana
    Adolescence is the period of transition between childhood and adulthood. healthy lifestyle habits acquired at this age prevent childhood alnutrition and also reduce risk of developing ncds in adult life. in this regard, school can act as a place which not only serve as an easy access point to target actions oriented towards improving child malnutrition but can also bring together all the stakeholders of the society associated with children health. therefore, a cross sectional study was conducted to assess the nutrition and health related practices followed in schools (n=60, 30 government and 30 private) of dehradun district and to identify which nutrition and health related practices followed in schools are predictors of malnutrition and good nutrition knowledge among school going early adolescents. schools were scored based on the nutrition and health related practices followed therein to categorise them as ‘average’, ‘above average’ and ‘below average’ schools. a validated tool with optimal reliability (cronbach's α =0.729 and test-retest reliability coefficient =0.79) was developed to assess the nutritional knowledge (n=397) of early adolescents (10-14 years) selected from ‘above average’ and ‘below average’ schools. also, their nutritional status was assessed through anthropometry, dietary assessment and presence of signs and symptoms of nutritional deficiency. apart from school category (‘above average’ and ‘below average’) results were also analysed based on gender (boys and girls) and school type (government and private). Univariate logistic regression analysis were performed to find association between nutrition and health related practices of schools (independent variables) with nutritional status (wasting, stunting and overweight) and nutritional knowledge of early adolescents. independent variables which were found to be significantly associated were further analysed through multivariate regression analysis to find predictors of wasting, stunting and obesity and good nutrition knowledge among early adolescents. based on performance of schools for nutrition and health related practices followed in them and their practices score, 70 per cent were in ‘average’ category whereas rest of the schools were equally distributed in ‘above average’ and ‘below average’ categories (15% each). both in ‘above average’ and ‘average’ categories percentage of government schools was higher (76.67% and 20% respectively), but in ‘below average’ category of schools percentage was higher for private schools (26.67%). average nutritional knowledge score of school going early adolescents was 34.02 ±4.67 (total score=48) and majority of early adolescents (88.7%) had fair to good nutrition knowledge level (>60% score). girls (or=2.35) and early adolescents from private schools (or=2.82) had better nutrition knowledge but school category wasn’t found to be associated. overall prevalence of stunting, wasting, obesity (overweight and obese) and abdominal obesity among early adolescents was found to 7.05, 23.43, 9.32 and 8.31 per cent respectively. under-nutrition (stunting & wasting) was predominant in government schools. while provision of an adequate eating environment (or=0.45) and presence of physical education teacher (or=0.54) in schools were found to be as predictors having protective effect on underweight prevalence, likelihood of stunting was less if early adolescents were studying in a private school (or=0.20). on the other hand over-nutrition (obesity & abdominal obesity) was high in private schools, and per week allocation of physical activity period (of 30-45 min) was found to as best predictor of overweight prevalence among early adolescents (lowest odds in schools providing daily physical activity period). abdominal obesity was prominent in boys (11.11%) compared to girls (5.26%). none of the anthropometric indices (bmi-for-age, height-for-age and waist-height-ratio) were found to be associated with the category of schools. clinical examination revealed the presence of anaemia, pem and b-complex deficiencies being more prevalent in early adolescent girls than boys. school practices such as involvement of school in any nutrition/health promotion program, presence of health committee in school, provision of school meals in an adequate eating environment, regular growth and health monitoring of children and conducting of health monitoring by medical practitioners, presence of physical education teacher (pet) in staff, and ifa supplementation at schools were also found to be associated with the nutritional status and nutritional knowledge of early adolescents on univariate analysis. in schools, existence of a health and nutrition policy, delivering appropriate physical and nutrition education, regular health monitoring, and provision of a safe and hygienic environment at school can be promising for improvement of nutritional status of early adolescents.

    Development and quality evaluation of ready to cook snack vadiyalu from black rice (Oryza sativa L.)
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-07) Inumala, Chandini; Kushwaha, Archana
    Black rice is a pigmented rice variety which is nutritionally superior over other rice varieties. Even it’s packed with many nutrients, it’s consumption is low in India due to the lack of awareness among people. Two black rice varieties BPT2841, Kalabati and one white rice MTU1121 grown in Andhra Pradesh were used for the study as the scientific data regarding nutritional and phytochemical profile of these varieties is limited. Rice varieties were subjected for the evaluation of their physical, milling, cooking, chemical and phytochemical properties using standard methods. Vadiyalu, a popular traditional snack of Andhra Pradesh was prepared out of these varieties and subjected to the nutritional and organoleptic evaluation. Rice grains under study therefore stand a good chance to be preferred by Indian consumers as they long slender type.The bulk density of paddy of both black rice varieties was lower than that of MTU1121 and hence they may require larger silo space as compared to MTU1121 for the same weight.Only local black rice variety Kalabati(23.82g) could qualify as desirable on the basis of thousand grain weight as value below 20g indicated the presence of immature, damaged or unfilled grains.Hulling and milling recovery percentage are found to be maximum in Kalabati (77.89 and 73.94%, respectively). The head-rice recovery percentage was found to be maximum in both black rice varieties (54.94 to 56.47%) when compared to white rice variety (52.31%). Milling efficiency percentage was also found to be maximum among black rice varieties (57.84 to 57.88%). Cooking time was maximum for BPT2841 (40.35min) and minimum for Kalabati (32.25min). Water uptake ratio was maximum for white rice (3.00) and minimum for Kalabati (2.17) which is the main reason that Kalabati required less water to make a soft dough during product development when compared to other rice varieties. Gruel solid loss was maximum in Kalabati because of its shape which could be lead to the leaching out of nutrients during cooking. Volume expansion ratio was found to be maximum in white rice (2.97) whereas similar in black rice varieties (1.71 to 1.76). Crude fat content of black rice varieties (1.47 to 2.54%) was comparatively high than white rice (0.75%). Crude protein content was found to be 1.6 times more in black rice than white rice. Crude fiber was found to be 2.5 to 3.9 times more in black rice than white rice. Total ash was found to be two times more than white rice. Starch content of white rice was found to be maximum in white rice (84.75%) than black rice varieties (76.53 to 80.89%). Dietary fiber content of black rice was found to be 4 times more than white rice (2.18%). Energy provided by white is comparatively more than black rice. Both black rice varieties were significantly superior over white rice in nutritional and phytochemical composition. Vadiyalu made of BPT2841scores maximum in sensory evaluation over white rice. Nutritionally, products made of black rice were superior over product made of white rice. Siginificant loss of anthocyanin after cooking was observed which needs to be stabilized for better nutritional quality. Dietary fiber, mineral content, total phenolic content, total flavonoid content, DPPH radical scavenging activity and anthocyanin content of both black rice varieties were much higher than control. Even though both black rice varieties were nutritionally rich, BPT2841was more feasible for the preparation of Vadiyalu because of its intermediate amylose content. Kalabati, because of its sticky nature made it difficult to formulate the product after cooking. Even though black rice existed since ancient times, due to urbanization food diversity has reduced greatly and leads to several non-communicable diseases. India has already achieved the better food security but nutritional security needs to be attained yet. As India is a country where people includes rice atleast once in a day, if they consume rice/rice products which is rich in micronutrients as well as phytochemicals, the health of the people can be promoted in long run. Inclusion of black rice in daily diets of people may help to attain sustainable nutritional security across nation.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-12) Anugya Bharti; Kushwaha, Archana
    The present study was undertaken for determining the prevalence of obesity among school going adolescents and to assess the dietary intake and its adequacy and level of physical activity among adolescents. The study also aims to determine the simple screening measure for identifying adolescents with overweight and obesity. A school based cross-sectional study was done in Rudrapur city. The prevalence of overweight and obesity was found to be 10.4% and 4.1%, respectively considering IAP reference standards as cut – offs with higher prevalence among boys than girls. Result of multivariate analysis showed that type of school and mother’s educational level were the factors that were found to be significantly associated with overweight. Only type of school was found to be significantly associated with prevalence of obesity. The odd of overweight and obesity was almost 1.7 times and 2.2 times, respectively higher in private school in comparison to government school. Energy, carbohydrate, sugar and fat intake was significantly higher in obese subjects in comparison to their overweight and normal weight counterparts. On comparing the nutrient intake of subjects with the RDA suggested for Indian adolescents, the adequacy of CHO and protein intake was found in more than 80% of the subjects whereas the adequacy of ascorbic acid and magnesium intake was found in 77.7% and 67.2%, respectively of the study population. The inadequate intake of iron and zinc was found in more than 40% of the study population. More than 50% of the subjects had inadequate intake of calcium, thiamine, riboflavin and niacin. Boys were having significantly higher physical activity in comparison to girls. In comparison to active child, inactive child (>60 min/day of MVPA) had 1.5 times more chance to become overweight. Similarly, in comparison to active child, inactive child had 2.4 times more chance to become obese. ROC curve analysis was done and on the basis of Youden index (sensitivity + specificity -1), Tri ponderal mass index (TMI) was found as best screening measure for identifying overweight and obesity among adolescents. The optimal TMI cut off value for screening overweight among adolescents were >12 kg/m3 and >13 kg/m3 for boys and girls, respectively. The optimal TMI cut off value for screening obesity among adolescents were >14 kg/m3 and >16 kg/m3 for boys and girls, respectively.

    The present study was conducted to analyze the physical characteristics, functional properties and nutritional composition of garden cress seeds. Physical characteristics included thousand seed weight, seed volume, seed density, bulk density, hydration capacity, hydration index, swelling capacity and swelling index. Functional properties included water and oil absorption capacity, gel consistency, gelation capacity and flour solubility of garden cress seeds flour. In nutritional composition, proximate composition, physiological energy, minerals, dietary fibre, in-vitro iron availability and in-vitro protein digestibility, antinutritional factors and antioxidants were analyzed. The findings of the study showed that thousand seed weight, volume and seed density of garden cress were 1.95g, 2.6 ml and 0.77 ml/g, respectively. The water and oil absorption capacity of garden cress seeds flour was 4.8 and 2.69 ml/g, respectively. The gel consistency, gelation capacity and flour stability of garden cress seeds flour was estimated as 48.78 mm, 7.90 per cent and 21.20 per cent, respectively. Moisture, total ash, crude protein, crude fat, crude fibre and total carbohydrate of garden cress seeds flour were estimated as 6.25, 4.89, 23.9, 12.68, 8.09 and 44.19 per cent, respectively. The physiological energy of garden cress seeds flour was found to be 386.28 kcal/100g. In-vitro iron availability and in-vitro protein digestibility of garden cress seeds flour was found to be 12.30 and 52.56 per cent, respectively. After nutritional analysis, sweet and savoury cookies were prepared by incorporating 10, 15 and 20 per cent of garden cress seeds (GCS) flour, in which cookies with 10 percent incorporation were found most acceptable on the basis of sensory evaluation. The nutritional composition analysis was done for most acceptable sweet and savoury cookies. Results obtained revealed that GCS incorporated sweet and savoury cookies were more nutrient dense than the control cookies. All the nutrients viz. crude protein, crude fibre, crude fat and minerals along with the antioxidants, in-vitro iron availability and in-vitro protein digestibility were significantly higher in cookies developed with 10 percent incorporation of garden cress seeds. Therefore, it can be concluded that products developed with incorporation of garden cress seeds flour are nutrient dense foods which may be used to manage the nutritional deficiency disorders.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-02) Suri, Shweta; Dutta, Anuradha
    The present study was undertaken to determine the prevalence of anaemia among children aged 3-6 years in U. S. Nagar district of Uttarakhandand develop an Iron-rich Ready to Eat (RTE) extruded snack, evaluate its quality characteristics and assess its in vitro iron bioavailability. Barnyard millet, defatted soy flour, amla (Indian gooseberry) powder and rice flour were used for development of the extruded snack. Results showed that prevalence of anaemia among subjects in the study area was 70.51 % with a mean haemoglobin level of 9.91g/dl (±1.9g/dl). Majority of subjects were moderately anaemic (59.28 %), followed by mildlyanaemic (31.27 %) and severelyanaemic (9.45 %). Cross-sectional survey showcased that majority of the subjects belonged to lower middle-class families having per capita income of 1130-2259 Rs./month (36.93 %). About 84.36 % of subjects belonged to nuclear familyand majority of families (47.18 %)had 3-4 children. Anthropometric assessment revealed that mean weight and height of the subjects was 16.62 ±4.02kg and 106.18±11.33cm. About6.41% subjects were underweight (low weight for age), 7.95% were stunted (low height for age) and 4.10% subjects were wasted (low weight for height). Dietary assessment revealed that majority of subjects were non-vegetarian (51.03%) and consumed three meals a day (73.33 %). Around 72.82% subjects consumed eggs and 71.79 % consumed milk regularly. About 32.31 % of the subjects had the habit of skipping meal. Clinical assessment showed that majority of subjects had normal hair, eyes, lips, tongue, teeth, gums, skin and nails. Personal hygiene data revealed that 88.21% subjects bathed daily. Majority of subjects used to walk barefoot (53.59%) and 30.51% subjects had intestinal worm infestation. Factors such as mother's illiteracy, monthly income of the household, history of anaemia among mothers, child barefoot walking, history of worms in child's stool, and lack of habit of hand washing were closely associated with the increased risk of anaemia among children as assessed inmultivariate regression analysis. Nutrient estimation of raw materials used for development of extruded snack revealed that defatted flour had the highest crude protein (48.34g/100g), crude ash (6.85g/100g), and calcium (157.74mg/100g) content. Barnyard millet showed highest crude fibre (11.25g/100g), crude fat (2.15g/100g), iron (16.49 mg/100g), total dietary fibre (28.00g/100g), total flavonoid (163.08mg RE/100g),and total antioxidant activity (60.54%).Amla was observed to have highest ascorbic acid (488.29mg/100g) and total phenol (208.04mg GAE/100g) content. BoxBehnken design of Response Surface methodology was used for optimization of process variables. Optimization revealed that blend ratio (6:1), barrel temperature (115°C) and amla (12.25g/100g of the total flour) was found to be highly acceptable combination for preparation of extruded snack. Optimized extruded snack was significantly superior than the control rice based extruded snack in terms of crude protein (18.91g/100g), crude fibre (2.33g/100g), crude ash (1.89g/100g) and crude fat (1.55g/100g). However, control snack had significantly higher carbohydrate (86.86g/100g) and physiological energy value (380.67Kcal/100g). Iron (15.71mg/100g), calcium (68.80mg/100g) and ascorbic acid (30.61mg/100g) content of optimized snack was significantly higher. Total phenol, total flavonoid and total antioxidant activity of optimized snack were significantly higher than the control snack. Physical parameters (length, diameter &volume) and textural property (crispiness) of control snack were better than the optimized snack. A non-significant difference was found between sensory properties of optimized and controlsnack. Keeping quality results of optimized extruded snack showed that microbial quality, moisture, free fatty acid, peroxide value and sensory quality were under acceptable limit for over 2 months storage at ambient temperature in both aluminum laminated and LDPE packets. Optimized extruded snack showcased significantly high in vitro iron bioavailability (42.61 per cent) as compared to control snack and composite flour. Therefore, it can be concluded that blend of barnyard millet, defatted soy flour, amla powder and rice flour can be successfully utilized for the development of iron rich Ready to Eat (RTE) extruded snack for improving the iron status of the population.
