UV-C处理对'黄金'百香果贮藏品质和采后生理的影响
Effects of Ultraviolet-C Treatment on the Storage Quality and Postharvest Physiology of'Golden'Passion Fruit
摘要
Abstract
In this study,'golden'passion fruit was used as the experiment material,and different doses of UV-C treatment(0,2.02,4.04,and 6.06 kJ/m2;the sample subjected to 0 kJ/m2 UV-C as the control)were used to treat the fruits before they were stored at 20℃for 18 d.Compared with the control,on the 9th day of storage,the UV-C treatment led to significant suppression on the decrease of L* value,the increase of b* value(P<0.05),and the decrease of titratable acid(TA)and flavonoid contents(P<0.05),while maintaining a* values as negative valuesand reducing the decay index and shrinkage index;The vitamin C contents of the fruits treated by UV-C at 2.02 or 4.04 kJ/m2 were 2.66 and 2.11 mg/100 g,respectively,which were higher than that of the control;The respiration rates of the fruits treated by UV-C at 2.02 or 6.06 kJ/m2 were 7.84 and 16.96 mg CO2/g FW h,respectively,which were lower than that of the control,although there was no significant effect on the content of total soluble solids,total phenolic content and firmness value(P<0.05);The UV-C treatment at 6.06 kJ/m2 increased cell membrane permeability and decreased total phenolic content.In general,the effect of the UV-C treatment at 2.02 kJ/m2 was better than those of the control and other UV-C treatments,thus can be used as an effective treatment to provide some theoretical guidance for the application of UV-C on postharvest passion fruit.关键词
