食用菌(Edible mushroom)由于其独特的风味和鲜嫩的肉质,在很多国家都被誉为佳肴。野生食用菌富含多糖、维生素和矿物质等,具有抗肿瘤和调节免疫等多种功能,是世界公认的不可多得的高营养兼药膳的"素中之荤"。和其他食物相比,野生食用菌富集重金属的能力强,由于矿物质和重金属会对人体产生积极和消极两种效应,近年来关于食用菌中矿物质和重金属含量的研究逐渐增加。本文对近年来野生食用菌的矿物质和重金属...
食用菌富集微量元素的研究进展
食用菌 微量元素 富集作用 研究进展
2016/6/28
微量元素是一类人体所必需的营养素,在自然界中多数以无机态形式存在,且分布不平衡,不易被人体吸收利用。近年来许多研究显示,食用菌对微量元素锌、硒、碘、铁等都具有富集和将无机态微量元素转化成有机态的功能。本文对食用菌富集微量元素的机理进行了归纳总结,概述了灵芝、香菇和金针菇等各类食用菌对微量元素的富集作用的研究进展。
