Priliminary study on extraction of ceramides from konjac fly powder by ultrasonic

QU Hao-liang

Abstract

The extraction of ceramides from konjac fly powder by ultrasonic was studied.The effects of temperature,time,proportion of solute to solvent and extracting solvent on the extraction efficiencies were analyzed.The optimum extraction conditions were made as follows:the temperature 60 ℃,time 35 min,proportion of solute to solvent 1∶4,extracting solvent 95% alcohol.The maximum of extraction efficiencies was up to 2.89%.
