Dongzao jujube is a type of fresh consumed fruit that originated in China. Because of its delicious flavor, tenderness, juiciness, and high nutritional Value, it is widely recognized as a promoting fruit in the future. Since the Dongzao jujube fruit normally ripens in early October, it is difficult to maintain storage for this plant at room temperature. In order to prolong the storage life and to be able to provide the fresh Dongzao jujube to markets for New Year’s Day and Spring Festival, different methods have been used for long-term storage of Jujube. Under 0 ^oC and RH 90%-95% storage conditions, large box package with plastic bags and small packages wirh PE films have proven to prolong the storage life of Dongzao jujube up to 80 days. But under lower temperature conditions of –2 ^oC and RH 90%-95%, plastic boxes coverde with PE showed the best results at the end of storage. The fruits could be stored for 100 days with good fruits rate of 90% or higher and no chilling injury. Some fungicides such as plant extraction, Deccozil 289-EC, were good for Dongzao jujube fruit storage. High oxygen pretreatment could prohibit the production of alcohol and the storage time can be prolonged further. This showed that the storage temperature is the most important factor in long term storage of Dongzao jujube fruit.
