Production of Rhodomyrtus tomentosa (Ait.) Hassk clarified juice by complex enzymatic method

Effects of complex enzymes on Rhodomyrtus tomentosa (Ait.) Hassk juice clarification were investigated. R. tomentosa (Ait.) Hassk was treated by pectinase and cellulose. Based on single-factor experiment, L9(34) orthogonal design was adopted to research the influences of complex enzyme proportion, enzyme dosage, enzymolysis time and temperature duration on juice yield. The results showed that pectinase and cellulose could enhance the juice yield and soluble solid content of R. tomentosa (Ait.) Hassk obviously, and the juice yield and soluble content of R. tomentosa (Ait.) Hassk under the optimum technological conditions of 0.4% enzyme dosage, 21 pectinase-cellulase ratio, 40 for 180 min enzymolysis time could reach 56.40% and 14.33 0Birx. Furthermore, the anthocyanins content of R. tomentosa (Ait.) Hassk was 169.28 mg/g.
