Abstract: Objective:It was studied to extract procyanidins from waste residue of grape winery. Methods:Ethanol solution was used for extracting procyanidins. Orthogonal design was used to optimize the better extract conditions. Result:The optimal extract conditions :After being broken into fragments and degreasing waste residue is twice extracted by 60% Ethanol and it takes 30min once. The obtained product's content of the procyanidins is 33.8% and the rate of obtain is 19.7%. Conclusion:The preliminary extract technology of procyanidins from grape seeds is established in our study.
Key words:waste residue of grape winery; procyanidins; extract of procyanidins
