Abstract: The radish was used as raw material, and was hydrolysed by pectinase and cellulase.The enzymatic maceration parameters were investigated by single-factor experiment and orthogonal design.Results indicated that the optimal enzymatic maceration conditions were as follows:pectinase concentration 0.20g/kg, cellulase concentration 0.60g/kg, pH5.0, hydrolysis temperature 45℃, and hydrolysis time 80min.Under these conditions, the juice yield was 80.13% and transmittance was 89.20%。
