Roots and tubers provide a substantial part of the world's food supply and are also an important source of animal feed. They are rich in energy, dietary fibre, minerals and antioxidants. A study was conducted to evaluate the neutraceutical components present in 5 types of minor tubers. Significant difference was observed among minor tubers for proximate, carbohydrate, and neutraceutical components. The protein, fat, carbohydrate, starch and energy content of the tubers ranged from 4.14 to 8.73 g, 0.07 to 0.67 g, 76.92 to 85.56 g, 33.97 to 69.18 g and 349 to 368 kcal per 100 g of sample respectively on dry weight basis. Estimated glycemic index of the tubers varied from 53.33 to 73.74. In vitro protein digestibility of the tubers ranged from 87.47 to 95.13, while polyphenols, tannins and antioxidant activity ranged from 87.04 to 245.5, 2.29 to 6.54 and 6.18 to 15.17%, respectively.
