    鸡蛋贮藏过程中品质变化的动力学模型

    Kinetics of quality change for eggs during storage

    • 摘要: 为研究鸡蛋贮藏过程中品质变化与贮藏期的相关性,采用动力学研究方法建立鸡蛋贮藏的预测模型。结果表明鸡蛋质量和蛋黄系数随着贮藏时间的延长而降低,气室高度随贮藏时间的延长而增加。一级化学反应动力学模型和Arrhenius方程对鸡蛋质量、蛋黄系数和气室高度变化具有较高的拟合精度。动力学反应速率常数表明贮藏温度越高,鸡蛋品质下降越明显。由预测模型所获得贮藏期预测值与实际值相对误差在10%以内,该模型可预测鸡蛋质量、蛋黄系数和气室高度在5~35℃范围内的变化情况和鸡蛋的贮藏期,为鸡蛋的贮藏和销售提供参考。

       

      Abstract: The relationship between quality changes and storage period of hen eggs was investigated, and kinetics method was adopted to establish the prediction model of storage. Results showed that the egg weight and yolk index decreased and the room height of egg increased with increasing storage time. The high regression coefficients indicated the acceptability of the first order reaction and Arrhenius model for predicting the changes of eggs weight, yolk index and air room height. Kinetics reaction rate constants suggested that the egg quality decreased with increasing storage temperature. Relative error between predicted shelf life calculated by the prediction model and observed value was within 10%. The change of egg weight, yolk index, air room height and storage period of eggs can be predicted at the storage temperature from 5℃ to 35℃ based on the prediction model of storage, which can provide a reference for the storage and sale of hen eggs.
