%X Through the determination of viscosity average molecular weight, enzyme activity, hydrolysis ratio and reducing sugar concentration, the optimal technological conditions of complex enzymes composed of commercial ?-amylase, cellulase and pectinase were investigated. Results indicated that complex enzymes could result in low molecular weight chitosan ranged from 1000 to 4000 after enzymatic degradation for 2 h under the condition of zymolyte ratio 1:5(m/m), pH 5.3 and temperature 56?, and the structure of those products failed to vary obviously by FTIR analysis.
