絮缘蘑菇子实体营养成分分析及蛋白质营养价值评价

比较分析絮缘蘑菇开伞（简称K型）和不开伞（简称T型）两种子实体的氨基酸、矿物质、维生素、蛋白质、脂肪、碳水化合物等成分，在现行国际氨基酸模式谱的基础上，通过氨基酸评分（AAS）、氨基酸比值系数（RC）、美国国家科学院医学研究所IOM模式评分、化学评分（CS）等多个指标进行分析和评价。结果表明：絮缘蘑菇富含多种营养成分、维生素和矿物质元素，含16种氨基酸，7种必需氨基酸和9种药效氨基酸。其中絮缘蘑菇（T型和K型）蛋白质含量（分别是32、29.2 g/100 g）是鸡蛋的2倍以上；矿质元素Zn(68、45.3 mg/kg)和Se(0.262、2.49 mg/kg)含量丰富，重金属元素含量符合国家标准；总氨基酸和总必需氨基酸含量高于香菇和鸡蛋，絮缘蘑菇T型较K型蛋白营养价值更高；9种药效氨基酸含量均达到总氨基酸含量的62%以上，鲜味氨基酸（F）和甜味氨基酸（S）含量丰富，F/S比值在1.8以上，高于香菇和双孢菇；必需氨基酸除甲硫氨酸外均符合国际推行的氨基酸平衡模式谱（AAS值均高于125.25%,IOM模式评分高于105%,RC系数在0.73～1.5,CS评分系数均优于鸡蛋）。综上絮缘蘑菇属...

Niutritional Component Analysis and Nutrition Value Evaluation of Agaricus subfloccosus Fruiting Bodies

In order to investigate the nutritional components and application value of Agaricus subfloccosus in the Qilian mountains. The amino acids, mineral elements, vitamins, protein, fat and carbohydrates of early-harvested (K type) and late-harvested (T type) were determined, and which were compared with Lentinus edodes, Agaricus bisporus and eggs. Based on the latest version of international amino acid reference patterns, amino acid score (AAS), ratio coefficient of amino acid (RC), IOM (Institute of Medicine) pattern score and chemical score (CS) were used to evaluated their nutrition value. The results showed that the fruitbody of Agaricus subfloccosus contained a considerable amount of nutrients, vitamins, mineral element and 16 free amino acids including 7 essential amino acids and 9 pharmacodynamic amino acids. The protein contents (32 and 29.2 g/100 g) of Agaricus subfloccosus (K type and T type) were more than twice of eggs, and the contents of mineral elements Zn (68, 45.3 mg/kg) and Se (0.262, 2.49 mg/kg) were higher, which were fit for the national standard, and the contents of total amino acids and total essential amino acids were higher than those of Lentinus edodes and eggs. The nutritional value of T-type protein was higher than that of K-type protein. The contents of 9 pharmacodynamic amino acids reached more than 62% of the total amino acids, the contents of delicious amino acids (f) and sweet amino acids (s) were rich, and the F/S ratio was more than 1.8, which was higher than that of Lentinus edodes and Agaricus bisporus. All the essential amino acids except methionine were accord with the internationally implemented amino acid balance model spectrum (AAS value higher than 125.25%, IOM model score higher than 105%, RC coefficient between 0.73~1.5, CS scoring coefficient better than that of eggs). In conclusion, Agaricus subfloccosus could be a delicious and high-quality edible and medicinal fungus. The results of this study would provide a scientific basis for further cultivation and promotion of Agaricus subfloccosus.
