| 中文摘要: |
| 以“达赛莱克特”草莓为试材，研究1%壳聚糖处理的草莓果实在0 ℃低温贮藏7 d后20 ℃常温货架6 d期间的品质变化规律。结果表明：与对照（0.1%醋酸溶液处理）相比，壳聚糖处理降低了低温贮藏后期和货架期草莓果实的呼吸速率、花青素、类黄酮及酚类物质的含量，保持较高的果实硬度，显著减少了货架期草莓果实腐烂和霉菌的发生，对果实失重率和可溶性固形物含量无显著影响。表明1%壳聚糖处理可有效延缓草莓的采后衰老进程，延长果实的货架期。 |
| 英文摘要: |
| Taking strawberry‘Darselect’ as test material, the effects of 1% chitosan coating treatment on storage quality of strawberry fruit were studied during 7 days cold storage at 0 ℃ and 6 days shelf-life at 20 ℃. The results showed that, compared with the control(soaking in 0.1% acetic acid solution), the chitosan coating treatment could reduce respiratory rate, anthocyanins, flavonoids and phenolic contents during late stage of cold storage and shelf-life, maintain higher fruit firmness, significantly decrease the occurrence of rotting and mildewing of strawberry fruit during shelf-life, and had no significant effect on fruit weight loss rate and soluble solids content. This study suggested that 1% chitosan coating treatment effectively extend the shelf-life of strawberry fruit. |
