| Abstract: |
| In order to scientifically guide the selection of nuts and dietary rationing, five peanut varieties of Lai Fang (LF), Yakou Xiaoliuqiu (YK), Zhukou Xiaozi (ZK), Wenheng Hongyi (WH) and Yang Hou (YH) with national geographical indications of agricultural products in Fujian were selected as the research objects, a total of 50 nutrients including seven types of nutrients, essential fatty acids, essential amino acids and some functional nutrition factors were used as evaluation indexes, and the degree of diversity (DD), degree of match(DM) and degree of balance(DB) of nutrients in peanut kernels were calculated. On this basis, the deviation index of the comprehensive evaluation index was calculated to obtain the comprehensive ranking of the nutritional value of five varieties of peanut kernels. The results showed that the DD of the five varieties of peanut kernels were the same, all containing 46 nutrients, but the MD were different. The MD of YH, LF, ZK, YK and WH were 0.933, 0.671, 0.449, 0.440 and 0.367, respectively. The DB of five varieties of peanut kernel nutrients were close, ranging from 0353 to 0.375. The deviation index (DI) of five varieties of peanut kernels was ranked from low to high as YH, LF, ZK, YK and WH. Therefore, among the five peanut varieties, the highest nutritional value is YH, and the lowest is WH. |
