摘要
为了科学指导坚果选购和膳食合理搭配,以福建地区5 个获全国农产品地理标志的花生品种("赖坊""衙口小琉球""朱口小籽""文亨红衣""洋后")为研究对象,以七大类营养素、必需脂肪酸、必需氨基酸和部分功能性营养因子共50 种营养素为评价指标,依次计算花生仁中营养素的多样度、匹配度和平衡度.在此基础上,计算综合评价指标偏离指数,获得 5 种花生仁营养价值的综合排序.结果表明:5 种花生仁营养素的多样度一致,均含有46 种营养素,但匹配度差异较大,"洋后""赖坊""朱口小籽""衙口小琉球""文亨红衣"的匹配度分别为0.933、0.671、0.449、0.440 和0.367;5 种花生仁营养素的平衡度比较接近,介于0.353～0.375 之间;5 种花生仁营养素的偏离指数从低至高排序为"洋后""赖坊""朱口小籽""衙口小琉球""文亨红衣".因此,5 种花生中营养价值最高的为"洋后",最低的为"文亨红衣".
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 0.353 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.
