Abstract: A new technology for extracting resveratrol from grape residue by enzyme hydrolysis was studied. Effects of enzymatic hydrolysis temperature and time,extraction temperature and time,and extraction time on resveratrol extraction were investigated. The optimal technological conditions are as follows:ratio of grape residue to cellulase 1000:1,enzymatic hydrolysis temperature 60 ℃,enzymatic hydrolysis time 90 minutes,adding ethyl acetate after enzyme hydrolysis for extracting resveratrol,extraction temperature 30 ℃,extraction time 0.5 h,and extraction times 2.

Key words: grape residue, cellulase, enzymatic hydrolysis, resveratrol
