摘 要：测定在4、15 、25 ℃储藏温度下蓝莓的硬度、失重率、腐烂率和可滴定酸含量4 种指标品质随时间的变化情况，结合试验人员对蓝莓感官指标的评分，建立蓝莓消费者整体满意度快速预测模型，提升蓝莓消费者的购买满意度。结果表明，蓝莓质量随储藏时间呈下降趋势，较低的储藏温度能减缓品质下降幅度;对参数进行逐步回归分析，腐烂率、色泽和气味3项指标对拟合模型不具有显著性（P>0.05），去除后得消费者满意度的快速预测模型。本研究结合品质客观变化规律和消费者主观评分，建立的整体满意度预测模型与品质变化情况拟合度较高，为消费者快速判断蓝莓品质、提升消费满意度提供理论依据和经验参考。

Abstract：Through the determination of blueberry hardness， weight loss rate， decay rate and titratable acid content changed with time at storage temperature of 4， 15， 25 ℃， respectively; combined with the score of sensory indexes of blueberry， the rapid prediction model of overall satisfaction of blueberry consumers was established to improve the purchase satisfaction of blueberry consumers. The results showed that： the quality of blueberry decreased with storage time， and lower storage temperature could slow down the decline of quality; stepwise regression analysis of the model parameters showed that decay rate， color and flavor had no significant effect on the fitting model （P>0.05）， and a rapid prediction model of consumer satisfaction was obtained after deletion. Based on the objective change of blueberry quality and the subjective score of consumers， the overall satisfaction prediction model had a high fitting degree with the change trend of blueberry quality， which provided theoretical basis and empirical reference for consumers to quickly judge blueberry quality and improve consumption satisfaction.

蓝莓，又称越橘，杜鹃花科越橘属，其果实中含有丰富的花青素、黄酮类化合物等多种生理活性成分[1]，具有抗氧化活性和一定的医学价值[2]，被联合国粮农组织（FAO）列为人类5大健康食品之一。随着社会经济的迅速发展和人民生活水平的提高，人们越来越倾向于营养价值高的食品，同时对品质也提出了更高的要求。近年……
