黄皮种子蛋白质营养价值的评价研究

在对黄皮种子氨基酸的组成及蛋白质的含量进行分析的基础上,应用模糊识别法和氨基酸比值系数法,对其营养价值进行了全面评价,并与8种植物种子蛋白质进行对照比较。结果表明:黄皮种子(干品)蛋白质含量为8.625%,含有17种氨基酸,种类齐全,其含量为762.2 mg.g-1蛋白质,必需氨基酸(EAA)占总氨基酸量的35.5%,第一限制性氨基酸为含硫氨基酸(M et+Cys),贴近度为0.8536,营养价值与高粱米、西瓜子等接近。

Evaluation of the Nutritional Value of Seed Protein from Clausena lansium ( Lour. ) Skeels

Based on the analyses of the amino acid compositions and contents of seed protein from Clausena lansium（Lour.） Skeels and putting 8 kinds of seed proteins of plants as a series of contrast,this paper evaluated their protein nutritional value by methods of fuzzy discernment and ratio coefficient of amino acid.The results show that contents of seed protein from Clausena lansium（Lour.） Skeels（dry sample） are 8.625%,containing 17 kinds of amino acids which accounted for 762.2 mg·g-1 protein.The essential amino acids take up 35.5% of total amino acids.The first limiting amino acid is sulfur-containing amino acids,Met and Cys.The close degree is 0.8536.The protein quality of seed from Clausena lansium（Lour.） Skeels have similar nutritive values to those seeds proteins from Sorghum vulgare and Citrullus lanatus（Thunb.） Mansf.
