基于挥发性盐基氮快速预测冷鲜鸡货架期

Shelf-Life Prediction of Chilled Chicken Based on Total Volatile Basic Nitrogen

  • 摘要: 为了解冷鲜鸡的货架期,以挥发性盐基氮(TVB-N)为品质表征参数,研究了冷鲜鸡在不同温度(5、10和15 ℃)下的变化规律,利用Arrhenius方程建立了不同温度下冷鲜鸡货架期预测模型,并对该模型进行内部验证和实际样本验证。结果表明:Arrhenius方程中TVB-N的活化能Ea为52.636 kJ/mol,指前因子k0为3.8×107。以5、10和15 ℃作为验证温度,其相对误差为6.30%,6.00%和3.91%,实际样本验证最大相对误差为−10.5%,说明该模型拟合效果好。通过该模型可快速获得不同贮藏温度下冷鲜鸡的货架期,为生产企业和监管部门制定货架期标准提供理论依据。

     

    Abstract: Arrhenius equation was used to establish the shelf-life prediction of chilled chicken based on total volatile basic nitrogen (TVB-N) at different temperature (5, 10 and 15 ℃). The prediction model was verified internally and with actual samples. The results showed that the Ea of the model was 52.636 kJ/mol, and that the k0 was 3.8×107. 5, 10 and 15 ℃ were selected as the internally verification temperature, while the relative errors were 6.30%, 6.00% and 3.91%, respectively. The maximum relative error of actual sample verification was −10.5%. These showed that the model could accurately predict the remaining shelf life of chilled chicken under certain conditions. In a word, the shelf life of chilled chicken at different storage temperatures could be obtained through the perdition quickly, and it would provide theoretical basis for manufacturers and regulatory authorities to formulate shelf-life standards.
