副干酪乳杆菌的天然抗菌物质。笔者在前期的研究中发现了含有广谱抗菌活性的新型细菌素FX-6，对真菌和细菌具有抑制作用。本研究通过微生物（活菌总数）、化学（TVB-N、pH）和感官评价，研究了抗菌物质对4℃条件下保鲜16 d的鲜肉品质和货架期的生物保鲜效果。5个处理分别为对照（无菌蒸馏水）、0.5%山梨酸钾溶液和3个水平的抗菌物质溶液（0.15%、0.6%和1.2%）。添加1.2%的抗菌物质可使猪肉在贮藏过程中保持良好的品质，延长猪肉的货架期，使猪肉的货架期延长至12天，并表现出良好的特性。这些结果表明，该抗菌物质具有作为冷鲜猪肉天然生物保鲜剂的巨大潜力。(C) 2015 Elsevier Ltd.版权所有。
The natural antimicrobial substance from Lactobacillus paracasei subsp. tolerans FX-6 was found containing novel bacteriocin with broad-spectrum antimicrobial activity to inhibit fungi and bacteria in our previous research. In present study, the biopreservative effect of the antimicrobial substance on quality and shelf life of fresh pork stored for 16 days at 4 degrees C were investigated based on the microbial (total viable counts), chemical (TVB-N, pH), and sensory evaluation. The five treatments evaluated included a control (sterile distilled water), 0.5% potassium sorbate solution and three levels of antimicrobial substance solution (0.15%, 0.6% and 1.2%). The antimicrobial substance could retain the good quality and extend the shelf life pork during storage and 1.2% antimicrobial substance could extend the shelf life to 12 days and the meat showed good characteristics. These results indicate that the antimicrobial substance has great potential as a natural biopreservative in chilled pork. (C) 2015 Elsevier Ltd. All rights reserved.
