摘要:采用亚硫酸盐释放出SO2气体还原***酸盐产生ClO2气体的发生方法,研制出稳定型双组份SO2-ClO2 保鲜剂。研究了不同比例的SO2发生剂与ClO2发生剂,并添加和丰膨润土制成片剂,对甜瓜、葡萄、杏子常见致病菌(青霉、黑曲霉)进行抑菌试验。结果表明:双组份SO2-ClO2最优配方SO2发生剂与ClO2发生剂质量比为1:,其保鲜效果优于单一使用SO2和ClO2。

Abstract: The use of sulfite release SO2 gas produced chlorate ClO2 gas reduction occurs method developed stable ponent SO2-ClO2 preservative. The proportion of SO2 by the occurrence of different agents ClO2 generating agent test results show that the optimal formula for SO2 generating agent / ClO2 generating agent mass ratio was 1/. Added abundance bentonite tablets of melon, grapes, mon pathogens(Penicillium, Aspergillus) for antibacterial test, through the colony diameter, inhibitory rate, spore germinat
