摘　　要：以八分熟的树莓为研究对象,在不同储藏温度(5,10,15,20和25℃)下研究其品质变化,通过Arrhenius方程建立树莓果实采后腐烂动力学预测模型。结果表明,树莓果实的腐烂与贮藏温度、时间有关,其关系符合零级动力学反应。贮藏温度过高,会对果实品质造成损伤,果实的腐烂程度导致货架期缩减。树莓果实采后腐烂预测模型相对误差为6.14%,准确度接近1,货架期模型SL=F_(y)/[1.83×10^(11)exp(-8.1×10^(3)/T)],相对误差为5.71%,准确度接近1。在5~25℃温度范围内,所建模型可对树莓果实采后腐烂及货架期进行预测。Eight ripe raspberry was used as the test material as the test material to study its quality changes at different storage temperatures(5,10,15,20 and 25℃),and a prediction model of the kinetics of fruit decay after harvest by Arrhenius equation was established.The results showed that the relative error was 6.14%,the accuracy was close to 1,and the shelf life model was SL=F_(y)/[1.83×10^(11)exp(-8.1×10^(3)/T)],with a relative error of 5.71%and the accuracy close to 1.The shelf life of raspberry fruit could be predicted in the temperature range of 5-25℃.
