板栗贮藏保鲜方法研究进展

Research progress on preservation of chestnut during storage

板栗采收期短,收获后果实水分含量高、新陈代谢快,且又被致密的内皮和果壳紧密包裹,很容易发生腐败变质,影响食品安全的同时,还造成严重的资源浪费。该文综述了板栗果实贮藏保鲜方法研究进展,从产地及品种、采收成熟度、采收堆制方式、贮前处理和贮藏环境等方面,阐述了影响板栗贮藏效果的因素;总结了包括沙藏法、冷库贮藏法、气调贮藏法、辐照处理和超高压技术在内的物理方法和涂膜保鲜处理、杀菌防腐剂等化学方法提高板栗贮藏保鲜的有效措施,以期为板栗贮藏保鲜研究提供参考和理论支撑。

Chestnut has a short harvest period.After harvesting,the fruit has a high moisture content,fast metabolism,and is tightly wrapped by the dense inner skin and husk.It is prone to spoilage,which affects food safety and causes serious waste of resources.This article reviewed the research progress of chestnut fruit storage and preservation methods.Moreover,from the aspects of origin and variety,harvest maturity,harvesting and stacking methods,pre-storage treatment,and storage environment,factors affecting the storage effect of chestnuts were expounded.Physical methods such as storage method,freezer storage method,controlled atmosphere storage method,irradiation treatment,and ultra-high pressure technology,and chemical methods such as coating preservation,sterilization,and preservatives were effective measures to improve the storage and preservation of chestnuts.This review provides a reference and theory for the research of chestnut storage and preservation.
