【摘要】 本实验分别用斜率法和坐标法测定了人工栽培的富硒平菇、富硒香菇和富硒金针菇的硒生物利用率,结果表明:血硒、肝硒和血浆谷胱甘肽过氧化物酶活力在各组均随补硒浓度的增加而增加,3种人工富硒菌菇的硒生物利用率均与亚硒酸钠接近。说明3种人工富硒菌菇都是食物硒的良好来源。更多还原

【Abstract】 Bioavailability of selenium in 3 kinds of cultivated Se-enriched mushrooms, namely Plearstus ostreatus, Lentinus edodes and Collybia roltipes were assayed in rats in two separate experiments. Their bioavailabilities were calculated by either the for mula advocated by Combs (ratios of slopes) or by plotting method. Indicators of selenium status used in these experiments in cluded blood, liver selenium and serum glutathione peroxidase activity. The relative bioavailabilities of selenium in all 3 culti vated enriched mushrooms were very close to that of selenite according to criteria of above 3 indicators, it demonstrating that these cultuvated Se-enriched mushrooms are excellent Se food source.更多还原
