The effect of different fruit bags on the browning and fruit quality of'Fojianxi'pear
To clarify the effect of different fruit bags on the browning of the skin and internal quality of'Fojianxi'pear,this study selected three different fruit bags(outer yellow and inner black,outer yellow and inner red,and outer yellow and inner white)for pre harvest bagging treatment.The results showed that compared with the outer yellow and inner black bags and the outer yellow and inner red bags,the outer yellow and inner white bags had the lowest browning rate and browning index of the fruit skin.They reduced the total phenolic content in the skin,as well as the content of phenolic acids such as chlorogenic acid,cryptochlorogenic acid,isochlorogenic acid A,and neochlorogenic acid.In addition,the content of proanthocyanin B2 and proanthocyanin C1 in the outer yellow and inner white bags was significantly lower than the other two fruit bags.The hardness,soluble solids content,and titratable acid content of the fruit in the outer yellow and inner white bags were the lowest,but the solid acid ratio,and the vitamin C content were the highest.Taking all factors into consideration,the outer yellow and inner white bag is the suitable fruit bag type for'Fojianxi'pear.
