对平菇、平菇、肺平菇和香菇的水分、蛋白质、总氨基酸、灰分和矿物质等营养成分进行了比较研究。蘑菇培养在相同的堆肥（小麦秸秆添加15%的甜菜），并在收获后立即分析，以避免任何干扰参数。还评估了限制性氨基酸，并计算了相关的蛋白质化学评分。所研究的食用菌的水分含量高（范围从85.2%至94.7%），灰分含量范围从6.9%至10.5%（以干基计）。钾是最丰富的矿物元素，其次是镁。总氮变化从3.47%至7.93%（干基），和P，ostreatus物种具有最大的变异性之间的样品分析。蘑菇中含量最丰富的氨基酸（以占总氨基酸的百分比表示）是谷氨酸（12.8-20.9%）、天冬氨酸（9.1-12.1%）和精氨酸（3.7-11.7%），但在分析的肺形菌和L.香菇中检测到特别低百分比的精氨酸（3.7%和5.7%）。化学评分通常为96 - 110%，限制性氨基酸为亮氨酸或/和赖氨酸。(C)1999爱思唯尔科技有限公司。保留所有权利。
A comparative study on various components of nutritional interest, such as water, protein, total amino acids, ash and minerals, in mushrooms of different species (Pleurotus ostreatus, Pleurotus eryngii, Pleurotus pulmunarius and Lentinula edodes) was carried out. Mushrooms were cultivated on the same compost (wheat straw added with 15% of sugar beet) and analysed immediately after harvest to avoid any interfering parameters. The limiting amino acid was also evaluated and the relevant protein chemical score was calculated. The moisture content of the edible mushrooms studied is high (ranging from 85.2 to 94.7%) and the ash contents range from 6.9 to 10.5% on a dry basis. Potassium is the most abundant mineral element followed by magnesium. Total nitrogen varies from 3.47 to 7.93% (dry basis), and P, ostreatus species has the largest variability among the samples analysed. The most abundant amino acids in mushrooms, expressed as percentages of total amino acids, are glutamic acid (12.8-20.9%), aspartic acid (9.1-12.1%) and arginine (3.7-11.7%), but in the analysed P. pulmunarius and L. entinus edodes a particularly low percentage of arginine (3.7 and 5.7%) has been detected. The chemical score generally ranges from 96 to 110%, the limiting amino acid being leucine or/and lysine. (C) 1999 Elsevier Science Ltd. All rights reserved.
