中文摘要：以真空包装罗非鱼为研究对象,通过不同温度（273、277、283K）下贮藏实验构建了真空包装罗非鱼的货架期预测模型。测定不同温度下真空包装罗非鱼的菌落总数、挥发性盐基氮（TVB-N）和脂肪氧化（TBA）值的变化,用Arrhenius方程建立了真空包装罗非鱼的品质变化与时间的动力学模型。菌落总数、TVB-N值和TBA值变化预测模型中的活化能（EA）和速率常数k0分别为53.5kJ/mol和4.390×108,25.9kJ/mol和8.96×103,29.3kJ/mol和4.92×104。验证结果表明：货架期模型预测值与实际值相对误差在±10%之内,可以在273-283K内,根据菌落总数、TVB-N值以及TBA值对真空包装罗非鱼的货架期进行预测。

外文摘要：The shelf-life prediction model of vacuum packing tilapia were established at different temperatures （273,277 and 283K, respectively） during storage. The indicators of Total Viable Count （TVC）,Total-Volatile Basic Nitrogen（TVB-N） and 2-thiobarbituric acid（TBA） were measured at the different storage temperature. The kinetic model between vacuum packing tilapia＇s quality and storage time was established based on the Arrhenius equation. The Activation energies （EA） and the rate constants （ko） of TVC,TVB-N and TBA were 53.5kJ/mol and 4.390x 10^8, 25.9kJ/mol and 8.96x 10^3, 29.3kJ/mol and 4.92x 10^4, respectively. The results showed that the higher the temperature arrived ,the faster reaction rate did ,while the relative error between the shelf-life model prediction value and the actual value was within ＋10%. According to the values of TVC,TVB-N and TBA from 273K to 283K,vacuum packing tilapia＇s shelf-life could be predicted accurately.
