等离子体活化水冰对纯培养及三文鱼片表面单增李斯特菌杀菌效果研究
Plasma-activated Water Ice Inactivation of Listeria Monocytogenes in Pure Culture and Salmon Strips
摘要
Abstract
The potential of PAW-ice for the inactivation of Listeria monocytogenes in pure culture or artifi-cially inoculated on salmon strips was firstly presented. Meanwhile, the main active substances in the plasma were detected by optical emission spectroscopy, and the oxidation-reduction potential ( ORP ) , pH value and electrical conductivity were also determined. Moreover, the effects of PAW-ice on the total volatile basic nitrogen ( TVB-N) and pH of salmon strips were determined. The results showed that, com-pared with sterile water-ice, PAW-ice had a remarkable effect on the pure culture of L. monocytogenes, which could reduce the bacteria by 1～3 lg CFU/mL, and the sterilization efficiency depended on the PAW’s preparation time, volume and PAW-ice processing time. In addition, during storage at 4℃ for 5 days, compared with sterile water-ice, PAW-ice could inhibit the growth of L.monocytogenes on the sur-face of salmon strips and slow down the increase of TVB-N and pH value. Thus, PAW-ice had a good prospect in controlling L.monocytogenes on the surface of salmon strips.关键词
