Optimization of Enzymolysis for Clear Concentrated Hawthorn and Tangerine Peel Juice
Enzymatic hydrolysis was used to develop clear concentrated hawthorn and tangerine peel jucie.The enzymes used for clear juice production were determined to be pectinase,cellulase,papain and tannase.With light transmittance and the actual production demand as the index,the optimal clear process was finally confirmed by single factor experiment and orthogonal experiment.The optimized clear process was as follows:0.4g/L of compound enzyme,pH 4.0,40℃～50℃for 4h.The transmittance of the concentrated hawthorn peel juice can reach 98%.
