摘要:
探究超声协同不同浓度苯乳酸(US+0.5% PLA、US+1% PLA)不同处理时间(5、15、30 min)对鸡胸肉表面金黄色葡萄球菌和沙门氏菌的杀菌效果,US+0.5% PLA处理15 min使菌数降低了0.67 lg CFU/g,US+1% PLA处理15 min使菌数降低了0.68 lg CFU/g,选取US+0.5% PLA处理15 min作为贮藏试验的处理条件,通过探究贮藏期间冷鲜鸡肉的菌数、pH值、挥发性盐基氮、硫代巴比妥酸及色泽的结果发现,处理组贮藏期间金黄色葡萄球菌和沙门氏菌的菌数始终低于空白组约1 lg CFU/g,贮藏6 d,空白组挥发性盐基氮值为36.67 mg/100 g,处理组的值比空白组的值低约10 mg/100 g,此时,空白组的硫代巴比妥酸值为1.15 mg/100 g,处理组为0.78 mg/100 g,显著低于空白组数值,结果表明超声与苯乳酸的协同处理(US+0.5% PLA)可有效抑制鸡胸肉表面的金黄色葡萄球菌和沙门氏菌的生长速率,且能延缓蛋白质分解及脂肪氧化,明显降低肉的TVB-N、TBA含量增长速率,且对鸡胸肉的色泽无显著性影响,使其贮藏期延长1~2 d。
