富马酸二甲酯(DMF)是二十世纪八十年代开发出来的一种新型防霉剂,分子式为C6H8O4,为白色片状或粉结晶,微溶于水,易溶于甲醇、乙酸乙酯、氯仿、丙酮等有机溶剂。富马酸二甲酯具有广谱高效的抗菌特性,对30多种霉菌、酵母菌和细菌都有很好的抑菌效果,因此,曾广泛应用于食品、化妆品和皮革等产品的防霉[1]。科学证实,食品中的富马酸二甲酯易 Dimethyl fumarate (DMF) is a new antifungal agent developed in the 1980s. Its molecular formula is C6H8O4, which is white flake or powder crystal, slightly soluble in water, easily soluble in methanol and ethyl acetate Esters, chloroform, acetone and other organic solvents. Dimethyl fumarate has a broad spectrum of highly effective antibacterial properties, has a good antibacterial effect on more than 30 kinds of molds, yeasts and bacteria, therefore, has been widely used in food, cosmetics and leather products such as mold [ 1]. Scientific evidence shows that dimethyl fumarate in food is easy
