摘要
采用向平菇栽培料中直接添加无机硒的方法,可使无机硒转化为有机硒并在菇体中得到有效的富集。实验表明:当加硒浓度在10～20mg/kg时,可使菇体中硒的富集量达70～120μg/100g鲜重,菇产量可增产3成左右。硒的利用率达4.081%和3.493%。菇体中生物活性物质多糖含量可达146.7299mg/g干重,VC含量可达20～21mg/100g干重,且采收的鲜菇不需经特殊处理即可上市出售。
The Se was accumulated in the fruiting-body by adding the Se to the culture medium of Pleurotus ostreatus, The results shows that： when the Se in the culture medium was in 10-20mg/kg, the Se in the fruiting-body could get 70- 120μg in 100g fresh weight. The fruiting-body yield could increased 30%. The 4.08% and 3.49% of the added Se could be accumulated in the fruiting-body. The amylose could get 146.3mg/g dry weight, vitamin C could get 20-21 mg/100g dry weight. For the concentration of the Se in the fruiting-body was in low level, So the fruiting-body of P. ostreatus was safety to eat.
