摘要:

【目的】研究不同预冷方式结合过氧化氢(H2O2)熏蒸处理对西梅采后贮藏保鲜效果的影响。【方法】以新疆生产建设兵团第三师东风农场西梅为试材,分别采用蓄冷周转箱、原位压差、冷库直冷式预冷并结合3% H2O2对西梅进行熏蒸及纳米聚乙烯微孔保鲜膜(N)包装的预处理措施,以无预冷及熏蒸处理为对照(CK),于1℃,湿度85%~90%的保鲜库中贮藏,通过定期测定西梅的生理指标,分析西梅在贮藏期间品质的变化规律。【结果】较对照组,三种预冷方式结合3% H2O2熏蒸处理,在一定程度上均有效保持了西梅的贮藏品质。不同处理组对西梅贮藏品质保鲜效果:原位压差预冷处理组>预蓄冷周转箱处理组>原位压差预冷处理组>冷库直冷处理组>CK。其中,原位压差预冷处理组较CK,呼吸强度推迟了30 d,预蓄冷周转箱和冷库直冷较CK组推迟了15 d。在第90 d,蓄冷周转箱、原位压差、冷库直冷处理组果实腐烂率分别为CK组的 61.2%、40.8%和51%,硬度分别较CK组分别提高了17.65%、70.6%和5.9%。原位压差预冷处理组更好的抑制了西梅的腐烂率、失重率,硬度、可溶性固形物、可滴定酸以及VC含量的下降速率,提高了果实SOD、CAT和POD的活性,阻止了西梅的软化,最大限度地保持了西梅的贮藏品质。【结论】采后预冷结合H2O2熏蒸处理对延缓西梅的衰老进程,保持较好的贮藏品质有促进的作用,尤其是隧道式原位压差预冷结合H2O2熏蒸处理维持西梅采后保鲜效果最佳。

Abstract:

【Objective】 To investigate the effects of different precooling methods combined with hydrogen peroxide (H2O2) fumigation on postharvest storage and fresh-keeping of prune.【Methods】 The Dongfeng Farm prune of Xinjiang 3rd Division was used as the test material. The prunes were stored at 1℃ and the humidity was 85%-90%. The physiological indexes of prunes were measured regularly. The prunes were stored at 1℃ and stored in a fresh storage room with no precooling or fumigation as control (CK). The quality changes of prune during storage were analyzed. 【Results】 Compared with the control group, the three precooling methods combined with 3%H2O2 fumigation treatment effectively maintained the storage quality of prune to a certain extent. Comparison of storage quality and fresh-keeping effect of prune in different treatment groups: In-situ differential pressure pre-cooling treatment group > pre-storage turnover box treatment group > cold storagedirect cooling treatment group > CK.Among them, the respiratory intensity of the in-situ differential pressurepre-cooling treatment group was delayed by 30 days compared with the CK group, and the pre-storage coldturnover box and cold storage direct cooling were delayed by 15 days compared with the CK group. On the 90th day, the fruit decay rates of the cold storage turnover box, in-situ pressure difference, and cold storage directcooling treatment groups were 61.2 %, 40.8 %, and 51 % of the CK group, respectively, and the hardness was17.65 %, 70.6 %, and 5.9 % higher than that of the CK group, respectively. The in-situ differential pressurepre-cooling treatment group better inhibited the decay rate, weight loss rate, hardness, soluble solids, titratableacid and VC content of the plum, increased the activity of SOD, CAT and POD, prevented the softening of theplum, and maximized the storage quality of the plum.【Conclusion】 Postharvest pre-cooling combined with H2O2 fumigation treatment has a positive effect on delaying the senescence process of prunes and maintainingbetter storage quality. In particular, tunnel in-situ differential pressure pre-cooling combined with H2O2fumigation treatment has the best effect on maintaining postharvest preservation of prunes.
