摘 要:
本文研究了养殖大黄鱼0、5℃冷藏过程中微生物、化学、感官品质变化,用修正的Gompertz方程描述细菌生长情况,结合TVBN和感官品质指标确定货架期并用指数腐败货架期模型加以验证.研究结果表明0、5℃冷藏货架期分别为408h和252h,货架期终点细菌总数分别为7.37±0.04、7.26±0.07lgCFU/g,TVBN分别为31.16±0.64、27.32±0.76mg/100g.用指数腐败方程预测3、5℃冷藏大黄鱼货架期,预测值和实测值的相对误差为5.6%～-14.9%,显示该方程可以快速可靠地实时预测0～5℃有氧冷藏大黄鱼的鲜度和剩余货架期.[著者文摘]

Abstract:
Microbiological, chemical and organoleptic quality changes for chilled Pseudosciaena crocea stored aerobically at 0, 5℃ were mainly assayed. The bacteria growth of chilled Pseudosciaena crocea was described by using modified Gompertz equation. The shelf life was assayed by using TVBN, for organoleptic and microbiological quality indexes, and then validated by using the exponential spoilage model. The results showed that the slielf life is 408 or 25211, TVC 7.37 ± 0.04 lgCFU/g or 7.26 ± 0.07 lgCFU/g, TVBN 31.16 ± 0.64, or 27.32 ± 0.76 mg/100g during the storage at 0 or 5℃, respectively. The shelf life on Pseudosciaena crocea at temperatures 3 ℃ and 5 ℃ were predicted by the exponential spoilage model. Basic errors between predicted shelf life and observed shelf life are 5.6% ～- 14.9%. The results indicate that the model is valuable for rapid and realistic prediction of the freshness quality and shelf life of chilled Pseudosciaena crocea stored aerobically from 0 to 5 ℃.[著者文摘]
