| Abstract: | The nutritional potential of short-horned grasshopper, Chondacris rosea (Acrididae) and mole cricket, Brachytrupes orientalis (Gryllidae), two common species of Orthoptera used as food by tribal people of Arunachal Pradesh (NE India), was assessed. C rosea and B. orientalis contain 68.88 and 65.74% crude protein, 7.88 and 6.33% fat, 12.38 and 8.75% crude fiber, 4.16 and 4.33% ash, and 6.69% and 15.18% carbohydrate, respectively. The protein in both species is composed of 18 amino acids, including all of the essential ones, which except for methionine, satisfy (scores > 100) the recommended dose suggested by FAO/WHO/UNU. The predominant fatty acids in C. rosea were: palmitic, stearic, oleic, linolenic and linoleic acid viz. 17.2, 12.4, 21, 24.5 and 16.4%, respectively. In B. orientalis palmitic (50.3%) and stearic acids (32%) were dominating. Mineral content was generally higher than that of conventional meat types. B. orientalis fulfilled the RDA (88–109%) for Fe and both species fulfilled the RDA for Zn (70 to 108%) and Cu (> 100%). Based on 100 g of fresh insects the calorific values of C. rosea and B. orientalis were 373.24 and 380.65% kcal. We conclude that these insects can be recommended as a replacement of vertebrate animal food items as and when required. |
