摘要: 应用模糊识别法和氨基酸比值系数法,以鸡蛋蛋白质为标准蛋白,以WHO/FAO氨基酸参考模式为评价标准,对乌饭树叶蛋白质营养价值进行了全面评价,并与4种植物叶蛋白质进行对照比较。结果表明:乌饭树叶蛋白质中总氨基酸含量为71.82%,蛋白质中氨基酸种类比较齐全,必需氨基酸(EAA)占总氨基酸量的40.30%,第一限制性氨基酸为赖氨酸,氨基酸比值系数分为77.05。

Abstract: Using egg protein and the WHO/FAO reference model on essential amino acid(EAA),4 plant leaf proteins were evaluated for their nutritional values.With them,the leaf proteins in Vacinium bracteatum were compared by applying the fuzzy pattern recognition and ratio coefficient of amino acid(AA).The results showed that 71.82% of the total amino acids of V.bracteatum was in the leaves.And,EAA comprised 40.30% of the total AA in the leaves.The greatest limiting AA in the protein was lysine.The ratio coefficient of amino acid was 77.05.V.bracteatum was,therefore,considered a potential protein source with high nutritional value.

Key words: Vacinium bracteatum, protein, amino acid, nutritional evaluation
