六氢β-酸对李斯特氏菌抑制作用的研究

Study on the Antimicrobial Action of Hexahydrocolupulone to Listerial Monocytogenes

本文研究了六氢β-酸对李斯特氏菌的抑菌活性影响。结果表明:5×10^(-6)g/ml的六氢β-酸对李斯特氏菌有明显的抑制作用。温度及酸碱处理对六氢β-酸的抑菌活性影响较少,但使用环境的pH值对六氢β-酸的抑菌作用有显著影响。肉制品保藏实验表明:六氢β-酸的防腐保鲜能力明显优于目前常用的食品防腐剂乳酸链球菌素(Nisin)、山梨酸钾及苯甲酸。

The antibacterial activity of hexahydrocolupulone(6H - β - acid ) to Listerial monocytogenes (LM ) was studied in this paper. The result showed that 5 × 10-6 g/ml 6H-β - acid had an obviously antibacterial action to LM. Temperature acid and alkali treatment had a few effect, hut pH value obviously effected on its antibacterial action. Experimental results of meat preservation showed that the antibacterial activity of 6H -β - acid was obviously superior to the common antiseptic such as Nisin, Benzoic acid and Potassium sorbate.
