可食性明胶抑菌膜抑菌性能评价

Edible Gelatin Antibacterial Film Inhibition Performance Evaluation

选用明胶为成膜基质,在膜液中添加山梨酸钾,制备抑菌膜。并进行酵母菌、霉菌、大肠杆菌和金黄色葡萄球菌的抗菌试验,结果表明胶抑菌膜对大肠杆菌、霉菌、酵母和金黄色葡萄球菌具有一定的抑制作用,其抑菌作用与山梨酸钾的浓度有关,山梨酸钾添加量越高,明胶膜的抗菌作用越明显。

Gelatin was used as the film-forming substrate,and the bacteriostatic film was prepared by adding potassium sorbate to the membrane liquid for the mildew mechanism of the potato powder.Antibacterial test against yeast,mold,Escherichia coli and Staphylococcus aureus were carried out.Through bacteriostatic test,gelatin bacteriostatic membrane has certain inhibitory effect on Escherichia coli,mold,yeast and Staphylococcus aureus,and its antibacterial effect and Yamanashi The concentration of potassium acid is related to potassium sorbate,and the antibacterial effect of gelatin film is more and more obvious.
