PROBLEM TO BE SOLVED: To solve following problems: former impregnation method of seasoning liquid to food requires long time for seasoning liquid to permeate enough； and in some cases, impregnation used to be impossible, methods which apply pressure to food dipped in seasoning liquid or dehydrate moisture of food are considered but, apparatus and facility became bigger for those methods process food, cost so much as to be unsuitable for mass production, and seasoning liquid did not impregnate within a short time and uniformly.SOLUTION: Processing seasoning liquid used for seasoning food with micro nano bubble generator enables impregnation to food within a short time, especially promoting impregnation of taste components other than salinity, and since the method processes seasoning liquid, equipment and facility can be simplified different from methods which process food so that cost can be reduced and energy can be conserved.
