【摘要】：為了明確薏苡飼用部位的氨基酸營養(yǎng)情況,以9個薏苡(Coix lacryma-jobi)資源的飼用部位為研究對象,測定其根、莖和葉的營養(yǎng)成分和氨基酸含量,并進行評價分析。結(jié)果表明:薏苡的根、莖、葉中均含有7種必需氨基酸和10種非必需氨基酸,各部位間氨基酸含量差異顯著,總體趨勢為葉根莖,其中臺灣紅衣薏苡葉的氨基酸含量顯著高于其他供試資源。薏苡飼用部位功能性氨基酸特別是藥用氨基酸含量豐富,占總氨基酸含量的59.34%~69.27%。通過氨基酸評分明確了(蛋氨酸+胱氨酸)是薏苡飼用資源的第一限制氨基酸,并通過分部位聚類篩選出2份氨基酸含量高的薏苡葉資源(臺灣紅衣薏苡和北峰野生薏苡),為薏苡飼用提供數(shù)據(jù)參考。
[Abstract]:In order to determine the amino acid nutrition of Coix lacryma-jobi (Coix lacryma-jobi) in Coix lacryma-jobi, the nutrient components and amino acid contents in roots, stems and leaves of Coix lacryma-jobi were determined and evaluated. The results showed that there were 7 essential amino acids and 10 non-essential amino acids in the roots, stems and leaves of Coix. The content of amino acids in Coix leaf was significantly higher than that in other resources. The content of functional amino acids, especially medicinal amino acids, in the feeding parts of Coix lachryma was rich, accounting for 59.34% of the total amino acids and 69.27% of the total amino acids. The amino acid score indicates that methionine cystine is the first limiting amino acid in the feed resources of Coix. Two species of Coix leaf resources with high amino acid content were selected by cluster analysis, which provided data reference for the feeding of Coix lacryma.
