梁河县滇皂荚的皂角米营养成分分析
|
摘要
采用国标和农业部部颁标准的方法,对云南省梁河县不同单株滇皂荚的10个皂角米样品中的一般营养成分、氨基酸和矿质元素含量进行了测定,并用灰色关联度分析法进行分析。结果表明:供试皂角米样品蛋白质含量2.37%~3.64%,总糖及粗纤维含量均低于1%;氨基酸种类齐全,包括8种必需氨基酸及9种非必需氨基酸,且氨基酸的E/T和E/N均符合FAO/WHO理想模式;富含K、P、Ca、Mg、Na、Fe、Zn、Mn、Cu等9种矿质元素,因此梁河县产皂角米是一种高蛋白、低糖、氨基酸齐全和矿质元素丰富,符合高K低Na饮食结构的营养保健食物。滇皂荚单株树龄与皂角米各类营养成分之间的关联序为氨基酸总量>蛋白质百分含量>粗纤维百分含量>矿物质元素总量>总糖百分含量。
Using GB/T and NY/T methods,the general nutrients,amino acids and mineral elements of 10 perisperm samples of different individuals of Gleditsia japonica var.delavayi from Lianghe County in Yunnan Province were determined.The results showed that all samples contained higher contents of proteins with 2.37-3.64%and lower content of total sugar and crude fibers under 1%.There are 8 essential amino acids and 9 non-essential amino acids contained in the all samples,and the 2 indexes E/T and E/N in all samples are according with FAO/WHO ideal model.In addition,the mineral elements such as K,P,Ca,Mg,Na,Fe,Zn and Mn are rich in the all samples.It is indicated that the G.japonica var.delavayi in Lianghe County is a kind of nutrition and health food with higher protein,lower sugar,rich in amino acids and mineral elements with high K and low Na.The grey correlation analysis showed that the correlation degree between plant age and various nutrients of G.japonica var.delavayi in order of total amino acid,protein content,crude fiber content,mineral elements,and total sugar content.
