食用菌富集重金属因素及其控制技术研究进展

食用菌是一类大型真菌,具有生长快、生物转化率高等特性,可将无机物高效、快速转化为有机可利用的功能性食物资源,富硒、富锗、高氨基酸等功能食用菌产品愈来愈风靡世界,但研究发现食用菌在快速转化生物质的同时,也大量富集了对人体有害的重金属、毒素等物质。论文综述了食用菌吸收和富集重金属基本原理、影响重金属在食用菌中富集的主要因素及控制和减低食用菌富集重金属的主要措施,这对进一步认识食用菌转化生物质过程、富集有害重金属的机理有理论指导意义,也对生产功能性食用菌,为人类提供健康食品具有实践价值。

Research Progress of Factors Accumulating Heavy Metals in Edible Fungi and Their Control Techniques

Edible fungi is a kind of large-scale fungus,which has the characteristics of fast growth and high bioconversion rate. It can efficiently and quickly convert inorganic substances into functional organic food resources. The edible fungi is rich in selenium,sputum and high amino acid and has become more popular in the world,but the study finds that when the edible fungus is rapidly transforming biomass,it also enriches heavy metals,toxins and other substances harmful to the human body. The paper reviews the basic principles of absorption and enrichment of heavy metals by edible fungi,the main factors affecting the enrichment of heavy metals in edible fungi,and the main measures to control and reduce the enrichment of heavy metals by edible fungi,which has theoretical guiding significance for further understanding the transformation process of edible fungi into biomass and the principle of enriching harmful heavy metals,and it also has practical value for producing functional edible fungi and providing healthy food for human beings.
