| 摘 要： | 研究了40%、60%、80%和100% O2 和空气气流连续处理对‘大乌’杨梅在5℃, 12 d贮藏期间腐烂和主要品质指标变化的影响。结果表明, 高氧处理对果实总酸、可溶性固形物、还原糖含量及pH值无明显影响; 但60% ～100% O2 处理可显著抑制果实贮藏期间的腐烂, 且O2 浓度越高, 果实腐烂越低,以100% O2 处理的作用最大。60% ～100% O2 处理还可以显著抑制果实失重率、花青素和丙二醛含量的增加, 保持较高的维生素C含量。结果表明, 高氧处理在杨梅果实采后贮运保鲜中具有潜在的应用前景。

| Abstract: | The effect of high oxygen atmosphere on Chinese bayberry (Myrica rubra Sieb. et Zucc) fruit decay and qualitywere investigated. Freshly harvested Chinese bayberries were placed in jars continuously ventilated with air orwith 40%, 60%, 80% or 100% O2 at 5℃ for 12 days. While the quality parametersof total titratable acidity, total soluble solids, reducing sugar and pH value were only slightly affected by the superatmospheric O2 levels. Treatments with 60% - 100% O2 significantly inhibited fruit decay incidence;there was a decrease in decaywith an increase in oxygen concentration. The 100% O2 treatmentwas the most effective in controlling fruit decay. Fruit treated with 60% - 100% O2 or higher also exhibited significantly higher vitamin C content and lower levels of weight loss, MDA and anthocyanin content. Data obtained suggest that high oxygen atmosphere may provide a potential alternative for postharvest decay control on Chinese bayberry fruit. |
