Research Progress on Preservation Technology of Ziziphus jujuba Mill. cv. Dongzao

Winter jujube is a major economic crop in Shandong Zhanhua, Shaanxi Dali, Hebei Huanghua and other regions in my country. It is loved by people because of its rich nutrition and crisp taste. Furthermore, it is a common seasonal fruit with large yield, affordable price and high market share. In this paper, the fresh-keeping technology of winter jujube is summarized, and the fresh-keeping technology of winter jujube is systematically discussed from three aspects of physics, chemistry and biology. It focuses on the application and current situation of modified atmosphere preservation and coating preservation technology. This paper provides a reference for the further development of winter jujube preservation technology, and at the same time provides a reference for the preservation of other jujube and its products, which further promotes the progress and development of the food industry.
