    摘要:

    比较不同贮藏温度对“黄妃”番茄果实采后生理和品质变化的影响,结果表明:“黄妃”番茄能耐受0 ℃低温贮藏,在15 d的贮藏期内不会发生冷害现象。不同贮藏温度下,“黄妃”番茄乙烯释放速率和呼吸速率总体呈下降趋势,其中20 ℃和16 ℃贮藏组在15 h出现乙烯释放高峰,且20 ℃和16 ℃贮藏组的乙烯释放速率和呼吸速率在整个贮藏期间显著高于其它温度贮藏组;果实失重率、腐烂率、色泽、果柄和萼片新鲜度明显受贮藏温度的影响,在0~20 ℃,贮藏温度越低,指标改善越明显;而果实硬度、可溶性固形物(TSS)和可滴定酸(TA)在15 d贮藏期内较为稳定,贮藏温度对其影响不显著。电子舌模糊风味感官评价结果表明,贮藏后的“黄妃”果实的风味感官有所变化,低温可使风味感官更接近于新鲜采收果实。综合失重、腐烂损耗和品质变化情况,0~8 ℃均适用于“黄妃”樱桃番茄的贮藏保鲜。

    Abstract:

    Present study investigated the effects of storage temperature on the physiology and fruit quality of 'Huangfei' cherry tomato. The results showed that, 'Huangfei' cherry tomato is tolerated to the above 0 ℃ low temperatures, without any chilling injury syndrome occurred in the 15 d storage. The ethylene release rate and respiratory rate showed a general trend of decrease with the elongation of storage time. A peak of ethylene release rate existed in the 20 ℃ and 16 ℃ groups at the 15 h. Both the ethylene release rate and respiratory rate were significantly higher in the 20 ℃ and 16 ℃ groups compared to the fruit stored under lower temperatures. The weight loss rate, fruit decay rate, color, freshness of carpel and sepals were significantly affected by the storage temperature, with the lower temperatures being more beneficial for the improvement of these index. The fruit hardness, TSS and TA contents remained stable in the 15 d storage, which were affected less by the storage temperature. The results of fuzzy sensory evaluation by Electric-tongue indicated that the flavor quality changed after storage, and the lower temperatures were more beneficial at maintaining the fruit quality. Taking the fruit loss and fruit quality into general consideration, 0-8 ℃ was suitable to be applied for the storage of 'Huangfei' cherry tomato.
