【中文摘要】 通過在100℃和126℃下滅菌及堆積發(fā)酵等處理的含87%棉籽殼的培養(yǎng)料來栽培平菇,然后測定平菇子實體中棉酚的含量,結(jié)果發(fā)現(xiàn)棉酚含量均在國家安全標(biāo)準(zhǔn)(?0.02%即200mg/kg)以內(nèi),其中以堆積發(fā)酵18d的培養(yǎng)料栽培得到的平菇子實體棉酚含量最低,只有24.00mg/kg。

【英文摘要】 Gossypol levels were determined in Pleurotus ostreatus fruit bodies grown on a substrate containing 87% cotton seed hulls that had been fermented for 18 d,or fermented for 3 d and then sterilized by autoclaving at 100 ℃ for either 240 or 600 min or at 126 ℃ for either 20 or 40 min. All samples contained gossypol levels that were below the National Security Standard (Q0.02%;200 mg/kg),with the lowest value (24.0 mg/kg) recorded in fruit bodies grown on the substrate that had been fermented for 18 days.
