预处理对增加红富士苹果细胞壁物质降解和出汁率的影响
Effect of Pretreatment on the Degradation of Cell Wall and Juice Yield of Red Fuji ＇Apple
摘要
Abstract
In order to enhance the degradation of cell wall and increase the juice yield through easy-operated pretreatment, ＇Red Fuji＇ apple were treated with two sets of selected conditions;500 mg/L Ethylene（E1 ） and 100 mg/L Ethylene plus 60℃hot water（E2）.Cell wall metabolism related enzymes,cell wall compositions and juice yield were measured.The results showed that E1 had stronger effect on ＇ Red Fuji＇ apple.The activ peak of pectin methylesterase（PME） and cellulase（CS） of ＇ Red Fuji＇ apple appeared 6d and 3d earlier than the control,respectively. The activity of polygalacturonase（PG） increased obviously than control till the 15th day.The activity of xylanase （Xyl） was essentially the same.After 12d later,the contents of pectin polysaccharides,hemicelluloses polysaccharides and cell wall material residue polysaccharides decreased to 80.1%,70.4%and 75.7%of the control and juice yield from ＇ Red Fuji＇ apple was 2.3～4.0 percentage higher than the control after 9～18 days.E2 inhibited PME activity,enhanced PG,Xyl,CS activity and increased degradation in most cell walls than the control.E2 gained 3.2%～7.1%higher of juice yield than the control during 0～9 days.关键词
