| 摘 要： | 目的研究货架期间猕猴桃的品质动力学变化特性与寿命。方法以"秦美"猕猴桃为实验材料,在温度为4,10,20℃下进行货架试验,测定猕猴桃质量损失率、硬度、可溶性固形物含量、可滴定酸含量、色值(C~*,L~*)的变化,利用Arrhenius方程建立相应品质指标的动力学模型,经恒等变形后得到货架寿命预测加权模型,并对模型进行验证。结果低温可以明显延缓猕猴桃在货架期间品质的降低,其品质变化均符合零级动力学方程;通过对比货架温度和时间对各品质指标的影响可知,货架时间均大于货架温度;综合上述品质指标构建的货架寿命预测加权模型,其相对误差在±10%以内,精确度较高。结论在温度为4～20℃范围内,可依据加权模型对猕猴桃的货架寿命进行准确预测。
