秦美猕猴桃的室温贮藏

Storage of Qinmei kiwifruit at room temperature

采用ＰＥ袋和保鲜剂方法对室温下贮藏秦美猕猴桃进行了研究．结果表明，袋内Ｏ２体积分数为１０％以上，ＣＯ２体积分数在２．５％～６％范围情况下，果实呼吸峰的出现推迟，峰值降低，果实贮藏期显著延长．袋内ＣＯ２体积分数高于６％，Ｏ２体积分数低于１０％时，则产生伤害．ＣＯ２体积分数低于２．５％时，贮藏期缩短．适合的ＰＥ－３袋加保鲜剂室温贮藏三个月，其猕猴桃果实硬度可保持在４．１０ｋｇ／ｃｍ２，好果率达９６．４％．

The experiments show that during the storage of Qinmei kiwifruit by PE bags and fresh storage agents in room temperature, when the CO 2 concentration is between 2.5%～6% O 2, concentration higher than 10%, the highest peak of fruit respiration could be delayed, and the value of peak could be lowered, hence the fruit storage period could be beneificially prolonged; when CO 2 concentration is higher than 6%, O 2 concentration, less than 10%, it should harm kiwifruit; when the CO 2 concentration is less than 2.5%, the fruit storage period will be short. 400kg kiwifruits stored three months by suitable PE-bags and fresh storage agents in room temperature, its′ firmness still remains 4.10 kg/cm 2 and good fruits reach the percentage of 96.4%.
