Abstract: 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.

Key words: skin residue of circasian fruit, pectin, extraction, method of alcohol precipitation
