Furthermore, consumers are increasingly aware of diet related health problems, therefore demanding natural ingredients which are expected to be safe and health-promoting. The agricultural processing industries produce substantial quantities of by-products, which are generally treated as waste of industry. This practice is not only a waste of resource, but also causes environmental pollution. In the present study corn silk, one of the byproducts of maize cultivation has been studied for its nutritional qualities to provide health benefit for the community and to enhance farmer’s income. In this study functional properties, nutritional composition and phytochemical analysis of processed corn silk powder of three corn varieties VL Baby Corn-1, CMVL Sweet Corn-1 and Hybrid Pant DH-291 were done. As per the results of nutritional composition corn silk powder reported to have good protein, crude fiber and mineral content especially calcium and iron. Corn silk showcased appreciable phytochemical composition in terms of total antioxidant activity and dietary fiber content. V.L Baby corn-1 reported highest antioxidant content whereas dietary fiber content especially insoluble dietary fiber was found in abundance in CMVL Sweet corn-1 in comparison to other two varieties. All the above-mentioned verities of corn silk have their individual significance which plays an important role in designing functional products. On the basis of result on analysis of corn silk powder of VL Baby Corn-1 was used in formulation of different flavoured herbal corn silk tea and corn silk powder of variety CMVL Sweet Corn-1 was for in (5 and 10 percent level along with control) development of various functional food items namely Chapatti, Parantha, Dal, Raita and Laddoos (Rice flour Laddoo, Papaya Laddoo, Sesame seed Laddoo). Results of sensory parameters showed upto 10 percent level of corn silk in all products were acceptable, also eight combination of corn silk tea along with control corn silk tea were accepted. Computed nutritive value of developed products got increasing trend in its nutritional value mainly protein, ash, fiber and mineral content with the increased level of corn silk powder upto 10 percent. Total antioxidant activity analysis of all teas combination showed blends with with Clove, Timur and Gandhraini found higher value than other blend of teas with corn silk..Result of prevalence study in U.S. Nagar showed 24% adult population was constipated among 995 subjects and females had more prevalence than males, contributing factors like insufficient intake of water, fiber and less physical activity were also associated with constipation. A fiber supplement in the form of corn silk powder sachets of 5 and 10 g were used in selected experimental groups of constipated subjects for 2 weeks to check suitability of corn silk powder for constipated population. During the dietary intervention, continuous monitoring was done daily by using Bristol Stool Form Scale upto 15th day. Result showed supplementation of corn silk fiber in the quantity of 5g and 10g was found beneficial. In case of 5 g supplement. symptoms got relieved between 48-72 h of consumption where as in case of 10g symptoms improved in 24-48 hours has therefore fiber supplement could be good strategy for treatment of constipation. Thus, it can be concluded that corn silk fiber has ameliorative characteristics towards improvement of defecation pattern and has potential for utilization as functional ingredient in health foods constipated population without additional input corn silk price may be added income for farmers.EnglishThesis
