The object of the present invention is to provide a process for maturing a food which makes possible to control the maturation degree of the food. Disclosed is a process for maturing a food characterized in that the maturation degree of the food is controlled by supplying energy 1 to a frozen food to control the period of time during which the food is maintained at a temperature in the neighborhood of its freezing point. Disclosed is a process for maturing a food characterized in that the food is matured by supplying energy 2 to a frozen food to adjust the period of time during which the food is maintained at a temperature in the neighborhood of its freezing point to a predetermined value or more. In a preferred embodiment, the melting time of a whole food is controlled by applying energy 3 which has a supplied calorie per unit time higher than that of energy 1 or 2 after the application of energy 1 or 2, and prolonging the application time of energy 3 to a predetermined value or more. In a preferred embodiment, a step is added which is for making the temperature gradient in the interior of a food approximately constant by applying energy 4 having a supplied calorie per unit time lower than that of energy 3 after the application of energy 3.
