Abstract
Disclosed is a method for processingjuice concentrate with good taste and stable color value, with the steps as follows: (1) pretreatment of raw materials; (2) high-temperature enzymolysis: adding the high-temperature amylase for enzymolysis 30 min at 95° C.; (3) juicing; (4) pasteurization; (5) acidity adjustment; (6) enzymolysis: adding raw materials of glucoamylase 747 ml/T pectinase 50 ml/T, activated carbon 3 kg/T, bentonite 1 kg/T to thejuice after acidity adjustment; (7) secondary pasteurization: cooling to 53° C.; (8) filtration; filtering through 0.45 um twice; (9) acidity adjustment, concentrating and cardboard filtration to obtain the finished product. The method for processingjuice concentrate provided herein is proved through experiments that, the conventional method for color protection by adding VC is not applicable forjuice concentrate, without adding VC, the browning during the product processing is significantly reduced, and the color value of final samples is well controlled; therefore, the method in the invention is simple, suitable for industrial production.
