不同包装方法对蓝莓采后贮藏品质和抗氧化活性的影响
Effect of Packaging on the Postharvest Quality and the Antioxidant Activity of Blueberry
摘要
Abstract
[Objective] This research was conducted to study the effect of packaging on the postharvest quality and the antioxidant activity of blueberry,and to explore the optimal packaging methods at low temperature.Further theoretical guide for the development and application of storage technique of blueberry.[Method] ‘Canlan’ blueberry fruits were stored at (5±0.5)℃ using unpacked,polyethylene (PE) film packaging and perforated PE film packaging.Based on sensory evaluation and analyses of antioxidant enzyme activities and antioxidant contents,the effects of different packaging methods on the postharvest quality and the antioxidant capacity of blueberry were studied.[Result] The results showed that,as compared to other two packagings,the PE film packaging was significantly better in preventing dehydration and atrophy,slowing down the changes of hardness and the total-soluble solids (TSS),and maintaining the antioxidant capacity of blueberry during storage.However,the PE film packaging showed no significant effect on titratable acid (TA) content.[Conclusion] Different packagings exhibited a great effect on the storage quality of blueberry fruit.By the end of the storage period (42 days),the fresh-keeping effect of the PE film packaging method was better than that of the perforated PE film packaging or non-PE-packed method.关键词
