摘要
探讨了以海红果皮渣为原料用酒精沉淀法提取果胶的工艺条件,结果表明:萃取液的pH=2.0、萃取温度为85±1℃,萃取时间为100min、用95%乙醇做沉淀剂时,可使果胶产率达40～45g/kg。
The experiment is designed to study the technical condition of pectin extraction from skin residue of circassian fruit in the method of alcohol precipitation. The result shows the extraction yield could be up to 40-45g/kg, with extract of pH=2 and 95% ethanol as precipitant at 85 ± 1 ℃ when being extracted in 100 minutes.
