Abstract: To optimize the extraction process of chlorogenic acid in sunflower kernel. The sunflower kernel was treated by meansof biocelluase and/or pectinase, studying the enzyme dosage, treatment time,treatment temperature how to influence thepercentage of the amount of chologenic acid in extraction. The amount of chologenic acid in extraction could be obviously increasedby the enzyme treatment. The optimum temperature of treatment was 40~50℃ and the optimum time was 1h. By doing theorthogonal experiment and by using the SAS software to analyze the result of experiment, to find the optimal parameter. Byusing the optimum parameter, the percentage of amount of chlorogenic acid was up to1.36%. The amount of chlorogenic acid wasalmost completely extracted. The amount of chlorogenic acid in extraction could be increased by enzyme treatment, and thechlorogenic was almost completely extracted.

Key words: sunflower kernel, chologenic acid, extraction
