摘要: 选取5个在形态特征和营养价值上具有代表性的毛木耳菌株——川耳1967、琥珀、川耳1985、川耳781和上海1号,测定其子实体蛋白质、氨基酸、粗多糖、灰分、维生素B2、钙、钾、铁、硒的含量,并基于国际氨基酸模式谱,采用氨基酸评分(AAS)、美国医学研究院(IOM)模式评分、氨基酸比值系数分(SRC)、化学评分(CS)、必需氨基酸指数(EAAI)以及蛋白质消化率校正氨基酸评分(PDCAAS)等多种指标,对这些品种的氨基酸营养价值进行综合评价。结果显示,5个毛木耳品种的营养成分多样,氨基酸种类丰富,必需氨基酸总含量为443.87~478.03 mg·g-1蛋白质,高于世界卫生组织/联合国粮食及农业组织/联合国大学(WHO/FAO/UNU)2007年推荐的平衡模式参考值、IOM推荐的模式参考值以及FAO推荐的鸡蛋蛋白改良模式值,可以作为机体蛋白源的有益补充。AAS、IOM模式评分、CS、EAAI和PDCAAS的综合评价结果显示,川耳781在氨基酸营养价值方面的表现最佳,是5个供试品种中的最佳蛋白质来源。本研究为毛木耳营养品质评价提供了一定的数据支持和方法。

Abstract:

In this study, five varieties of Auricularia cornea Ehrenb with representative morphological characteristics and nutritional value-Chuan’er 1967, Amber, Chuan’er 1985, Chuan’er 781 and Shanghai NO.1 were selected to determine the contents of protein, amino acid, crude polysaccharide, ash, vitamin B2, calcium, potassium, iron and selenium in the fruit body. Amino acid score (AAS), Institute of Medicine (IOM) model score, amino acid ratio coefficient score (SRC), chemical score (CS), essential amino acid index (EAAI) and protein digestibility corrected amino acid score (PDCAAS) were used to evaluate the nutritional value of these varieties. The results showed that the nutrients of these five varieties were diverse and the amino acids were rich, and the total essential amino acids contents were between 443.87 and 478.03 mg·g-1 protein. It exceeds the balance model reference values recommended by the World Health Organization/Food and Agriculture Organization of the United Nations/United Nations University (WHO/FAO/UNU) in 2007, the model reference values recommended by the IOM and the egg protein improvement model values recommended by FAO, which can be used as a beneficial supplement to the body’s protein source. According to the comprehensive evaluation results of AAS, IOM model score, CS, EAAI and PDCAAS, Chuan’er 781 was the best protein source among the five varieties in terms of amino acid nutritional value. This study provided some data support and methods for the nutritional quality evaluation of Auricularia cornea Ehrenb.

Key words: Auricularia cornea Ehrenb, nutrients, amino acid, nutritional value evaluation
