PURPOSE:To prepare a dry food which can be reconstituted or reconstituted and cooked to give a food having nearly the same palatability as that of the original food or the cooked original food, by rapidly evacuating a food under specific condition to effect freezing of the water in the food, and drying the product with heat. CONSTITUTION:A food is transferred from a pressurized state to an evacuated state rapidly enough to cause the expansion of the food and the freezing of water in the food. The change from the pressurized state to the evacuated state increases the degree of expansion. The food is maintained to the evacuated state until the water in the food is frozen, preferably until the lowering of the food temperature is stopped after the complete freezing, and is dried with heat by conventional heating means such as infrared heating, microwave heating, etc. |
