Abstract

The chemical composition of three Mexican strains of Pleurotus ostreatus (INIREB-8, CDBB-H-896 and CDBB-H-897), were determined. The mushrooms were cultivated on wheat straw in a greenhouse (22-28 degrees C temperature and 80 +/- 5% of relative humidity). Fruits bodies of P. ostreatus contained (all values are expressed in g/100 g dry wt.), protein (N x 6.25): 24.64 +/- 0.21-28.50 +/- 0.26; lipids: 1.10 +/- 0.16-1.85 +/- 0.22; mineral matter: 7.66 +/- 0.23-8.79 +/- 0.25; dietary fibre: 32.14 +/- 0.14-36.81 +/- 0.40; and available carbohydrates: 26.33 +/- 1.04-30.46 +/- 0.21. They contain vitamins (mg/100 g dry wt): riboflavin: 3.31-3.7, thiamin: 1.92-1.96, niacin: 35.98-36.56 and ascorbic acid: 28-35. The main fatty acid was linoleic (0.70-1.19 g/100 g dry wt), it was also reported a low calcium and phosphorus content. Concluding the Pleurotus ostreatus could be a source of some of the complex B vitamins, dietary fiber, protein and linoleic acid.

摘要

测定了三株墨西哥平菇菌株（INIREB - 8、CDBB - H - 896和CDBB - H - 897）的化学成分。这些蘑菇在温室中以麦秸为培养基进行栽培（温度为22 - 28摄氏度，相对湿度为80±5%）。平菇子实体含有（所有数值均以g/100g干重表示）：蛋白质（N×6.25）：24.64±0.21 - 28.50±0.26；脂质：1.10±0.16 - 1.85±0.22；矿物质：7.66±0.23 - 8.79±0.25；膳食纤维：32.14±0.14 - 36.81±0.40；以及可利用碳水化合物：26.33±1.04 - 30.46±0.21。它们还含有维生素（mg/100g干重）：核黄素：3.31 - 3.7，硫胺素：1.92 - 1.96，烟酸：35.98 - 36.56，以及抗坏血酸：28 - 35。主要脂肪酸为亚油酸（0.70 - 1.19g/100g干重），同时还报道其钙和磷含量较低。结论是平菇可能是某些复合B族维生素、膳食纤维、蛋白质和亚油酸的来源。
