PURPOSE:To obtain essence making the most of taste, flavor and fragrance of roasted beans, capable of being concentrated and causing no turbidity even by hot packing when it is concentrated, by subjecting an extracted solution of the roasted beans with water to an enzymatic reaction with cellulase. CONSTITUTION:Roasted beans such as coffee beans, soybeans, black soybeans, etc., are roasted to give roasted beans, which are crushed or ground and extracted with water by a conventional procedure. When or after the beans are extracted, the extracted solution in an upper tank is reacted with cellulase. After the enzymatic reaction is over, the reaction mixture is cooled to normal temperature or cold temperature and filtered to give a purified solution, which is optionally concentrated. |
