贮前温度处理对采后浆果贮藏特性影响的研究进展

浆果酸甜可口,且富含维生素、矿物质等人体必需营养素和多酚类等抗氧化活性物质,但其皮薄、多汁,极不耐贮藏运输,因此采后浆果保鲜是该产业亟待解决的问题。贮前温度处理作为无毒、无污染、操作简单的保鲜技术,符合人们对食品安全的要求且操作成本低。本文总结归纳了热处理与冷激处理两种不同贮前温度处理方式对采后浆果类水果贮藏特性的影响,以期为采后浆果贮藏保鲜方式的合理选择提供理论参考。

Advances in Effects of Prestorage Temperature Treatments on Storage Characteristics of Postharvest Berry Fruits

Fresh berry fruits are sour-sweet and tasty, and are rich in vitamins, minerals and other essential nutrients and antioxidants such as polyphenols. Fresh berry fruits have characteristics as thin and juicy, which bring great difficulty for storage and transportation. Hence the preservation of fresh berry fruits had become problem demanding prompt solution for berry fruits industry. As non-toxic and pollution-free technology with simple operation, prestorage temperature shock treatments could satisfy the food safety requirement of people and its cost is low. This paper summarized the effects of preheating treatment methods on the storage characteristics of postharvest berry fruits in two different ways of heat treatment and cold shock treatment. It would provide a theoretical reference for the rational selection of postharvest berry storage in preservation methods.
