冰鲜鲫鱼贮运过程中最佳用冰量确定及货架期预测

Ice amount determination and shelf-life prediction of ice-stored crucian carp during storage and transportation

  • 摘要: 本文研究了不同用冰量对鲫鱼品质的影响;结合Arrhenius方程,建立了动力学预测模型。在5℃贮运环境下,研究了50%、100%、150%、200%加冰量对冰藏期间鲫鱼感官品质、挥发性盐基氮(TVB-N)值、pH、弹性变化和货架期的影响,且在15、25、35℃三个温度下进行货架期加速实验,研究鲫鱼TVB-N值的反应动力学,建立鲫鱼贮藏期预测模型。结果表明:不同用冰量对鲫鱼品质有显著影响,结合实际贮运时间和成本考虑,选择150%为最佳用冰量。鲫鱼TVB-N值的反应动力学符合零级动力学模型,活化能(Ea)为35kJ/mol。在7、18、32℃贮藏条件下对鲫鱼贮藏期预测模型进行验证,相对误差为8.89%。由此表明,该模型适用于冰鲜鲫鱼贮藏期预测。 

     

    Abstract: The influence of different amount of ice on the quality of crucian carp were studied in the paper; Arrhenius equation were applied to establish dynamic prediction model of crucian carp.At 5℃, the effect of 50%, 100%, 150%and 200% amount of ice on sensory quality, total volatile basic nitrogen ( TVB-N) value, pH, elasticity and shelf life of crucian carp was studied. Meanwhile, shelf life accelerating test under 15, 25 and 35℃ was conducted, respectively.The kinetics of TVB-N changes and the shelf life prediction model was established.Results indicated that the different amount of ice had significant effect on the quality of crucian carp, considering the actual time and cost of storage and transportation, the 150% amount of ice was chosen; the calculated data of TVB- N were satisfactorily described by a zero order kinetic model with the active energy ( Ea) 35kJ /mol.The verification test of crucian carp stored under 7, 18, 32℃ showed that the relative error of shelf life prediction model was 8.89%.As a conclusion, the established models could be used to predict the quality of ice-stored crucian carp satisfactorily.
