本文研究了臭氧水-乙醇(75%)联合预处理结合气调包装(MAP,80% O2+20% CO2)[1]用于冷鲜猪肉的保鲜效果。通过以未经过臭氧水-乙醇(75%)预处理的MAP做对照组,试验研究了臭氧水-乙醇(75%)联合预处理:浓度分别为5ppm,8ppm,12ppm,15ppm,20ppm的臭氧水进行关键工序冲洗,联合乙醇(75%)进行入库前表面喷洒的不同组合方式对冷鲜猪肉气调保鲜期的影响。结果表明:臭氧水-乙醇(75%)预处理能有效减少冷鲜猪肉原始的带菌数,减缓贮藏期间细菌增殖速率和TVB-N值的增加速度,以及减缓MAP冷鲜猪肉感官品质的下降。综合分析臭氧水-乙醇(75%)联合预处理对冷鲜猪肉贮藏期间感官品质、肌肉持水力、菌落总数、TVB-N 值的影响,确定以12ppm臭氧水-乙醇(75%)联合预处理这一组合效果最好,与同条件单一乙醇(75%)预处理对照组比较,贮藏货架期延长7-13d。
本文研究瞭臭氧水-乙醇(75%)聯閤預處理結閤氣調包裝(MAP,80% O2+20% CO2)[1]用于冷鮮豬肉的保鮮效果。通過以未經過臭氧水-乙醇(75%)預處理的MAP做對照組,試驗研究瞭臭氧水-乙醇(75%)聯閤預處理:濃度分彆為5ppm,8ppm,12ppm,15ppm,20ppm的臭氧水進行關鍵工序遲洗,聯閤乙醇(75%)進行入庫前錶麵噴灑的不同組閤方式對冷鮮豬肉氣調保鮮期的影響。結果錶明:臭氧水-乙醇(75%)預處理能有效減少冷鮮豬肉原始的帶菌數,減緩貯藏期間細菌增殖速率和TVB-N值的增加速度,以及減緩MAP冷鮮豬肉感官品質的下降。綜閤分析臭氧水-乙醇(75%)聯閤預處理對冷鮮豬肉貯藏期間感官品質、肌肉持水力、菌落總數、TVB-N 值的影響,確定以12ppm臭氧水-乙醇(75%)聯閤預處理這一組閤效果最好,與同條件單一乙醇(75%)預處理對照組比較,貯藏貨架期延長7-13d。

Effects of modified atmosphere packaging (80% CO2+20% O2)combined with ozonated water-ethanol treatment on keeping chilled fresh pork quality were studied. Chilled fresh pork were treated by ozonated water in 5,8,12,15,20ppm separately,and disinfected by ethanol (75%). After being treated by ozonated water-ethanol, it was showed that original bacteria count in chilled fresh pork was evidently reduced. TVB-N value was slowed pro-moting and sensory quality was well controlled. Based on the evaluation of effect of ozonated water-ethanol treat-ment potency on sensory quality, total bacteria count, TVB-N value, peroxide number and water holding capacity of the chilled fresh pork during MAP storage, it could be concluded that 12ppm ozonated water-ethanol(75%) coalition treatment was the best one for keeping the chilled fresh pork quality. Shelf life of the chilled fresh pork could be extended 7 to 13 days, compared with the untreated group(CK group).
