为确定气调包装酱牛肉的腐败限值,以感官评定为标准,结合酱卤肉制品微生物要求,分析了气调包装酱牛肉在不同温度下贮藏时其感官评分、菌落总数、硫代巴比妥酸(TBARS)、总挥发性盐基氮(TVBN)等指标的变化规律.结果：10℃、25℃、37℃下酱牛肉腐败时,TBARS值大于0.22mg/100g、0.23mg/100g、0.25mg/100g,而不超过0.34mg/100g、0.27mg/100g、0.25mg/100g,TVB-N值大于18.63 mg/100g、17.96 mg/100g、23.83 mg/100g,而不超过20.75mg/100g、20.30mg/100g、23.83mg/100g.结果 表明结合感官和微生物指标判定酱牛肉腐败指标,在不同温度下有差异,综合评价更加合理.
