摘　　要：果实在运输过程中会因振动产生挤压、碰撞或摩擦损伤,这些损伤会影响果实在贮藏过程中的品质。以振动时间的长短为变量,研究不同的振动时间对杨梅贮藏过程中的二氧化碳含量和品质的影响。结果显示:振动处理会增强杨梅的呼吸强度,增加包装内的二氧化碳含量,振动12 h处理的杨梅在硬度、花色苷、维生素C、总抗氧化性方面均低于其它处理组杨梅的品质。相关性结果显示:杨梅包装内的二氧化碳含量与维生素C、总抗氧化性、硬度呈强负相关,与可滴定酸、花色苷呈一般负相关,与可溶性固形物呈弱相关。在物流贮藏过程中,杨梅包装内的二氧化碳含量在一定程度上反应杨梅的品质。利用多元线性回归方程,以杨梅上述品质指标构建的货架寿命预测模型,能较好地预测杨梅不同振动时间处理后的贮藏时间。The fruit will be crushed,collided,and damaged due to vibration during transportation,and these damages will affect the quality of the fruit during storage.In this paper,the length of the vibration time was used as a variable to study the effect of different vibration time on the changes of carbon dioxide concentration and quality of Myrica during storage.Research results showed that vibration would increase the respiratory strength of Myrica and increase the carbon dioxide concentration in the package.The quality of Myrica treated with 12 hours of vibration in terms of firmness,anthocyanins,vitamin C,and total antioxidant properties were lower than the quality of other Myrica treatments.Correlation analysis showed that the concentration of carbon dioxide in the Myrica packaging was strongly negatively correlated with vitamin C,total antioxidant capacity,and firmness,and was generally negatively correlated with titratable acids and anthocyanins,and weakly correlated with soluble solids.The concentration of carbon dioxide in the Myrica packaging could reflect the quality of Myrica to a certain extent in the process of logistics storage.Using multiple linear regression equations,the shelf life prediction model constructed with the above-mentioned quality indicators of Myrica can better predict the storage time of Myrica after different vibration time treatments.
