PROBLEM TO BE SOLVED: To provide a method for preserving coffee roasted beans having excellent flavor even after the lapse of time after extracting. SOLUTION: This method for preserving the coffee roasted beans comprises preserving roasted beans at 0°C to -30°C within 48 h, preferably 24 h after roasting so as to hold carbon dioxide in the roasted beans. In more details, a temperature of coffee roasted beans just after roasting is about 200°C, and the temperature is decreased to ordinary temperature (10°C to 28°C) by forcibly cooling which may be by any method. In the case of shipping roasted beans, the roasted beans are cooled, after cooling to ordinary temperature, to 0°C or below within 48 h, preferably 24 h and preserved. A cooling temperature may be 0°C or below, but preferably 0°C to -30°C, and even after cooling, it is preferable to hold at 0°C to -30°C. COPYRIGHT: (C)2009,JPO&INPIT
