Abstract:
North eastern India is blessed with potential source of starch i.e., sweet potato, discoscorea, jackfruit seed and tapioca etc. Starch has numerous applications in various industries like food, textiles and pharmaceutical industries. So various non-conventional sources (sweet potato, discoscorea, jackfruit seed, buckwheat, taro and tapioca) were used to extract starch and their proximate analysis, yield and amylose content were analyzed in the present study. Yield of starch was highest in discoscorea i.e., 84% and amylase was highest for 26.1% for taro starch. Non-conventional sources of starch such as sweet potato, jackfruit seeds, dioscorea are good and have been less utilized as compared to conventional sources. So, it is necessary to utilize these underutilized crops for their use in many food and non-food applications. Non-conventional starches and their value addition have increasingly been gaining importance in recent years because of their potential application as functional ingredients in the development of new products.
