摘　　要：本文研究了不同处理方式(臭氧处理、SO2保鲜纸缓释技术和自制乙烯脱除剂处理)对甜樱桃冰温储藏保鲜效果的影响。通过考察在贮藏期内樱桃硬度、Brix值和酶活性等生理指标及樱桃的失水率、腐烂率的变化,评价处理方式的优劣。研究表明,利用活性炭和酸性高锰酸钾制备的乙烯脱除剂可以有效的延长甜樱桃贮藏期,当贮藏时间为63d时,腐烂率仅为13.3%。SO2缓释保鲜纸虽然在维持甜樱桃生理活性方面有较好的作用,但对甜樱桃的损伤比较大,靠近保鲜纸的果品容易变色。臭氧处理的甜樱桃样品在前4周有较好的保鲜效果。自制乙烯脱除剂可以作为甜樱桃低温保藏的方法,对甜樱桃贮藏具有重要意义。Studied on the effects of preservation under the different treatments condition （Ozone treatment, the tin foil low releasing SO2treatment and the ethylene sorbent treatment） of sweet cherry nearing the freezing point in this paper. To evaluate the effects of different treatments, the changes of hardness, Brix value, and the enzyme activity of the sweet cherry and filtration and decay rate of the cherry during the storage time are investigated. Results showed that the ethylene sorbent, which is made of activated carbon and acid potassium permanganate preparation, could prolong the storage time of sweet cherry to 63 days, and the decay rate was only 13.3%. Although the tin foilslow releasing SO2 could maintain physiological activities of sweet cherry and make a good effect, but it could damage the color of the sweet cherry too where nearby the tin foil. Ozone treatment of sweet cherry sample had good preservation effects on the first 4 weeks. Homemade ethylene sorbent could be used in freezing temperature preservation of sweet cherry, and make a sense.
