摘　　要：以非真空避光包装方式处理鲜花椒,定期测定在不同贮藏温度(−20、4、25、40℃)下鲜花椒中总酰胺含量、挥发油含量、感官品质,在此基础上分别建立贮藏过程中酰胺物质和挥发油的动力学模型,为花椒采后加工储运和销售中的品质监控提供参考。结果显示:结合Arrhenius方程建立青花椒酰胺货架期模型、青花椒挥发油货架期模型、红花椒酰胺货架期模型、红花椒挥发油货架期模型,活化能Ea分别为52.68、50.00、49.85、50.62 kJ·mol^(−1),指前因子k0的自然对数ln k_(0)分别为18.13、16.98、17.15、17.08,经验证,模型能够以总酰胺含量和挥发油含量为品质指标对鲜花椒的货架期进行预测。Fresh fruit of Zanthoxylum was packaged in non-vacuum and dark environment,and the total fagaramide content,volatile oil content and sensory quality were determined periodically at different storage temperatures(20,4,25 and 40℃).The dynamic models of amides and volatile oil during storage were established respectively,which provided reference for quality control in processing,storage,transportation and sales of Zanthoxylum after harvest.The results showed that the shelf life model of Zanthoxylum armatum fagaramide,Zanthoxylum armatum volatile oil,Zanthoxylum bungeanum Maxim fagaramide,Zanthoxylum bungeanum Maxim volatile oil were established by Arrhenius equation.The activation energy Ea was 52.68,50.00,49.85,50.62 kJ·mol^(−1),respectively,and the natural logarithm lnk_(0) was 18.13,16.98,17.15,17.08,respectively.After verification,the established models can predict the shelf life of fresh Zanthoxylum with total fagaramide content and volatile oil content as quality indexes.
