山梨酸诱发产生高浓度黄曲霉毒素B1实验报告
Experimental Report on High Concentration Porduetion of Aflatoxin B1 Induced by Sorbic Acid
-
摘要: 山梨酸及其钾钠盐是近年来各国普遍使用的一种食品防腐剂。不少文章报导山梨酸毒性小,对霉菌、酵母菌和需氧菌均有较好的抑制作用。但山梨酸对黄曲霉毒素B1(AFB1)产生的作用,人们还了解较少,为此我们对山梨酸影响AFB1的产毒作用作了探讨实验,现将实验结果报告如下。Abstract: The effect of sorbic acid,aworldwide utilized food pre-servative,on the produetion of aflatoxin B1(AFB1)was studied. The results showed that sorbic acid of 0.10% concent ration inhibited the growth of Asperigillus flavus,0.05% concen-tration delayed the production of AFB1. Little amount of AFB1 were found insamples with 0.0125% sorbic acid after eulturing for 7 days and increase dgradually the reafter.
