摘要
[Objective] The precipitation conditions of salting out method for extracting shaddock peel pectin were studied.[Method] Taking shaddock peel as the raw material, the optimal technological conditions for pectin precipitation were obtained by precipitating shaddock peel under dif-ferent salting-out conditions.[Result] The optimal conditions of salting out method for precipitating shaddock peel pectin were as follows: aluminum sulfate saturated solution: pectin extract 1∶1, salting out time 60 min, salting out temperature 60℃, salting out pH 4, and the extraction rate reached 6.8%.[Conclusion] Precipitation of pectin through salting out method reduced the consumption of ethanol, energy consumption and production cost.
