短波紫外线处理对采后草莓果实腐烂和抗氧化能力的影响
EFFECT OF UV-C TREATMENT ON FRUIT DECAY AND ANTIOXIDANT ACTIVITY OF STRAWBERRY
摘要
Abstract
The influence of UV-C treatment on postharvest decay and antioxidant activity of strawberry fruit(Fragaria ananassa Duch.Fengguan) was investigated.Freshly harvested strawberry fruits were treated with 0,1.5,3.0,and 4.5 kJ·m-2 UV-C light and stored at 10℃ for up to 12 days.Samples were randomly selected initially and at 3-days interval during storage.Treatment of 3 kJ·m-2 UV-C light significantly inhibited the fruit decay incidence and MDA accumulation,delayed the losses of fruit weight,firmness,and TSS content,induced the increase of CIRG value,and maintained higher sensory quality in strawberry fruit.Meanwhile,UV-C treated at 3 kJ·m-2 accelerated the increase of total anthocyanin,total phenolic content and DPPH radical scavenging activity during storage and maintained higher antioxidant activity in strawberry fruit.Data obtained suggest that 3 kJ·m-2 UV-C may provide a potential alternative for postharvest decay control and antioxidant regulation on strawberry fruit.关键词
