摘要
[目的]本研究旨在明确气调贮藏对草莓贮藏期品质的影响。[方法]以"红颜"草莓为材料,分别在0℃、4℃、0℃空气、0℃气调等条件下进行贮藏,定期取样检测贮藏期内果实失重率、硬度、色度、抗坏血酸含量和表型等各项品质指标后,对比各指标间的差异变化。[结果]在0℃,4%CO_2+10%O_2条件下贮藏的草莓的品质最佳,贮藏至第15天时失重率仅为0.24%,硬度为518.65 N,抗坏血酸含量为0.46μg·g^(-1),显著优于其他贮藏条件(P<0.05),且能维持鲜亮的色泽、无病害发生,与对照相比货架期延长了7～9 d。[结论]0℃,4%CO_2+10%O_2处理是一种有效可行的草莓保鲜方法,可为草莓的贮运保鲜提供理论依据和技术参考。
[Objective]The study aimed to determine the effect of controlled atmosphere on the shelf life and fruit quality of stored strawberries.[Methods] Strawberry cultivar 'Hongyan' were selected and stored under various conditions(0 ℃、4 ℃、0 ℃ in the air、0 ℃ with modified atmosphere). Indicators of product quality of strawberries including phenotype, weight loss, ascorbic acid content, rigidity, and fruit skin color were investigated at certain time intervals during the storage.[Results] Storage at 0℃ with 4%CO2+10%O2 resulted in lower weight losses(0.24%), higher rigidity(518.65 N) and ascorbic acid content(0.46 μg·g-1) of strawberries with better skin color. The shelf life was also extended by 7~9 days compared to the control.[Conclusion]Controlled atmosphere is an effective and feasible method for strawberry preservation, and this study could provid technique reference for storage and distribution of strawberry products.
