<p>PURPOSE:To obtain the subject inexpensive food, excellent in reconstituting properties and good in preservation quality by introducing a food regulated to a prescribed moisture content into a pressure vessel, impregnating the food with gaseous carbon dioxide and subjecting the food to quick heat treatment and then hot-air drying treatment. CONSTITUTION:A food, such as cabbage or grains, regulated to 10-60% moisture content based on dry weight is placed in a pressure vessel and gaseous carbon dioxide is then introduced into the pressure vessel to keep the pressure thereof under >=10kg/cm<2>. Thereby, the gaseous carbon dioxide is impregnated into tissues of the food. The pressure of the above-mentioned pressure vessel is subsequently opened to take the afore-mentioned food impregnated with the gaseous carbon dioxide from the pressure vessel. The taken out food is then subjected to quick heat treatment and then hot-air drying treatment to reduce the moisture content to <=10% based on the dry weight. Thereby, the objective food suitable as an instant food, such as instant noodle or 'MISO' (fermented bean paste) soup, and material for processed foods is obtained.</p> |
