对桑枝杆为主原料栽培的秀珍菇(Pleurotus pulmonarius)鲜菇的有益与有害成分(农药残留、重金属)进行了初步分析,结果表明:鲜菇含水分88.4%、蛋白质4.23%、多糖0.35%、粗脂肪0.08%,含鲜味氨基酸谷氨酸(Glu)0.43 g/100g、门冬氨酸(Asp)0.29 g/100g,共计为0.72 g/100g;含甜味氨基酸丝氨酸(Ser)0.14g/100g、甘氨酸(Gly)0.15 g/100g、丙氨酸(Ala)0.15 g/100g、脯氨酸(Pro)0.14 g/100g,共计为0.58 g/100g。有害成分砷0.003 mg·kg-1、铅0.011 mg·kg-1、汞0.001 mg·kg-1;未检出农药六六六、滴滴涕,残留均低于《绿色食品食用菌》标准的规定。此外,蛋白质含量折干值达36.47%,多糖含量折干值达3.02%,即蛋白质、多糖含量较高;粗脂肪折干值为0.69%,即粗脂肪较低。因此,以桑技杆栽培的秀珍菇味道鲜美、清甜,营养、保健价值高,是一种优质菇品,值得大力生产开发。
The beneficial and harmful components (pesticide residues, heavy metals) of fresh mushrooms of Pleurotus pulmonarius cultivated with mulberry branches were primarily analyzed. The results showed that the fresh mushrooms contained 88.4% of water, 4.23% of protein, 0.35% of polysaccharides, , 0.08% of crude fat, 0.43 g / 100 g of glutamic acid (Glu), 0.29 g / 100 g of aspartic acid (Asp), 0.72 g / 100 g in total; 0.14 g of sweet amino acid serine (Ser) / 100g, glycine (Gly) 0.15g / 100g, alanine 0.15g / 100g, proline 0.14g / 100g, totaling 0.58g / 100g. Harmful components arsenic 0.003 mg · kg-1, lead 0.011 mg · kg-1, mercury 0.001 mg · kg-1; pesticides not detected BHC, DDT, residues are lower than the “green food edible mushrooms” standards. In addition, the protein content of dry fold value reached 36.47%, polysaccharide content of dry value of 3.02%, that is, protein, polysaccharide content; crude fat dry value of 0.69%, that is, low fat. Therefore, the mushroom cultivation with mulberry bar taste delicious, sweet, nutritious, high health care value, is a high quality mushroom products, it is worth vigorously production and development.
