摘要: 研究贮藏期间果实品质生理变化,探讨不同优质苹果品种的贮藏特性。以‘岳帅’、‘望山红’、‘岳阳红’、‘秋富红’苹果为试验试材,在(0±0.5) ℃、相对湿度90%~95%冷库内贮藏,定期测定果实呼吸强度、硬度、可溶性固形物(TSS)、可滴定酸(TA)、维生素C(Vc)含量、果实失重率、多酚氧化酶(PPO)活性、过氧化物酶(POD)活性,分析果实生理品质指标变化与贮藏特性的关系。结果表明,‘岳帅’苹果呼吸强度及酶活性较低,但呼吸高峰出现早,贮藏84d后果实品质劣变迅速;‘岳阳红’苹果呼吸强度和酶活性较低,贮藏期间果实品质、风味保持最好;‘望山红’和‘秋富红’苹果呼吸高峰出现最晚,果实品质保持较好。通过理化指标和感官评价比较得出结论:‘岳帅’贮藏期较短,不宜超过84d;‘岳阳红’、‘望山红’和‘秋富红’苹果适宜长期贮藏,其中‘岳阳红’苹果在贮藏过程中品质及营养成分损失最少。

Abstract: Changes in physiology and quality of apples under cold storage were researched to reveal the storage characters of different varieties. ‘Yue shuai’, ‘Wang shanhong’, ‘Yue yanghong’ and ‘Qiu fuhong’ apples were stored under temperature 0℃±0.5℃, relative humidity 90%~95%. The respiration intensity, firmness, total soluble solid content, titratable acid content, Vc content, weight loss ratio, PPO activity and POD activity of apples were measured, and the relationship between indicator changes and storage characters was analyzed. The result showed that: ‘Yue shuai’ apples had the lowest respiration intensity and enzyme activity, but the peak time appeared early, fruits deteriorated quickly after stored more than 84 days. ‘Yue yanghong’ apples had low respiration intensity and enzyme activity, the quality and flavor were retained best compared with others during storage. The respiration peak of ‘Wang shanhong’ and ‘Qiu fuhong’ apples appeared late, the quality was retained good during storage. In conclusion, ‘Yue shuai’ apples had the shortest storage life, ‘Yue yanghong’, ‘Wang shanhong’ and ‘Qiu fuhong’ apples could be stored for longer time, and ‘Yue yanghong’ retained the best fruit quality after storage.
