    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

    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.

    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) Agarwal, Garvita; Dutta, Anuradha
    The present study entitled, “study of overweight/obesity among adolescents of Nainital district and use of IEC module to tackle the problem” was undertaken with a view to assess thepresence of overweight and obesity in Nainital district among adolescents identify dietary and lifestyle factors responsible for overweight/obesity and evaluate an IEC module that had been developed as a management tool to reduce the problem. In phase I, a study was conducted among 357 adolescent from Haldwani and Ramnagar blocks of Nainital district, Uttarakhand. In phase II, an IEC (Information, Education and Communication) module was developed. The IEC module was aimed to improve the knowledge status and bring healthy lifestyle changes of adolescent in the study. The effectiveness of IEC module was also assessed through an intervention study in a group of adolescents (30 experimental and 30 control) pre and post intervention knowledge in test was done and anthropometric indicators were also assessed. The results of the study showed that age, education status of respondents, father and mother education status had a positive correlation with respect to BMI, and family size of the respondents had a negative correlation with respect to BMI. Exercise time per day, mobile playing per day, T.V watching per day had a positive correlation with respect to BMI and sleep per night and sleep after school had a negative correlation with respect to BMI. Number of meals per day and drinking water per day had a positive correlation. Only the consumption of fruits, and nuts and oil seeds had a negative correlation with respect to BMI. When IEC module exposure was shown at intervals then a significant difference in knowledge score was observed at all the stages in experimental group. A statistically significance difference in knowledge score was only observed in the last exposure between the two groups. A statically significant difference in weight was observed in the experimental group after each exposure which was statically non-significant in the control group at all durations of IEC exposure. A statically significant difference was seen in the BMI of the experimental group in all the stages of exposure. A statically significant difference was found between the BMI of experimental and control group of respondents on 1st day and at 3rd exposure (after 9 week). The data revealed that the increase in height of the experimental group exposed to IEC module at regular intervals was greater than the control group, and decrease in weight of the experimental group exposed to IEC module at regular intervals was greater than the control group indicating that motivation to the adolescent for leading a healthy life style may have a positive impact on their overall health and nutritional status. Overall a significant positive impact of IEC module exposure was observed on the respondent’s height, weight, BMI, and knowledge score. The IEC module developed in the present study proved to be effective in improving knowledge pertaining to overweight and obesity among adolescent. Result also showed good retention of knowledge gain. So, the module may be implemented to a larger extent with multiple exposures to bring a change in overweight and obesity presence among adolescent.
