食用菌富集微量元素的研究进展

Research progress in bioaccumulation of trace elements in edible fungus

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。

Trace elements are a series of nutrition that needed necessarily by human beings. In nature,trace elements are existed in inorganic form,unevenly distributed and not easy to be absorbed by human body.In recent years,the trace elements such as zinc,selenium,iodine,iron could be accumulated and transformed their inorganic state into organic state by many kinds of edible fungus,which were indicated in many researches.In this paper,the mechanisms of accumulation of trace elements in edible fungus were generalized,the research progress in accumulation of trace element in Ganoderma lucidum,Lentinus edodes,lammulina velutipes and other kinds of edible fungus were summarized and the prospect were predicted.
