Optimized phenolics from oregano and cranberry extracts were evaluated for antimicrobial activity against Listeria monocytogenes in laboratory media and in beef and fish. The antimicrobial activity increased when oregano and cranberry extracts were mixed at a ratio of 75% oregano and 25% cranberry (wt/wt) with 0.1 mg of phenolic per disk or ml, and the efficacy was further enhanced by lactic acid. The inhibition by phytochemical and lactic acid synergies was most effective when beef and fish slices were stored at 4 degrees C.
对牛至和蔓越莓提取物中的优化酚类物质进行了评估,以研究其在实验室培养基以及牛肉和鱼肉中对单核细胞增生李斯特菌的抗菌活性。当牛至和蔓越莓提取物按75%牛至和25%蔓越莓(重量/重量)的比例混合,每片或每毫升含0.1毫克酚类物质时,抗菌活性增强,并且乳酸进一步提高了其功效。当牛肉片和鱼片在4摄氏度下储存时,植物化学物质和乳酸协同作用产生的抑制效果最为显著。
