- 摘要:
- 采用酸法提取毛酸浆果实中的果胶,同时考查了纤维素酶辅助酸法提取果胶的效果,比较了酸法及酶辅助提取果胶的得率及酯化度。结果表明:酸法提取果胶的最佳条件为:料液比1∶4、温度90℃、pH 2.0、时间80 min,在此条件下果胶得率为1.74%,果胶的酯化度为65.1%。纤维素酶浓度选择0.3%、酶解时间90 min,酶解后酸法提取果胶得率为2.56%,果胶的酯化度为52.1%。
- Abstract:
- The purpose of this study was to isolate pectin from Physalis pubescensL.fruits by aqueous acid medium and cellulase-assisted pretreatment,the yield and degree of esterification(DE,%)were compared.The results showed that the appropriate extraction conditions by aqueous acid medium were:ratio of material to solvent 1∶4,temperature 90℃,pH 2.0,extraction time 80 min,the yield was 1.74%,and the DE was was 65.1%.Meanwhile,the concentration of Cellulase was 0.3%,enzymolysis duration 90 min,and the yield was 2.56%,the DE was 52.1% depending on the cellulase-assisted pretreatment.
