PROBLEM TO BE SOLVED: To extremely reduce the number of bacteria or sterilize bacteria in a food material, by only processing the food material such as vegetables or fruits for a short time, without using a substance toxic to a human body at all.SOLUTION: A food material such as vegetables or fruits is immersed into an aqueous solution of calcium oxide or calcium hydroxide, and fine bubbles having 20-60 μm of average particle size are supplied into the aqueous solution, to bring the food material into contact with the saturated aqueous solution and the fine bubbles for 5-20 minutes.COPYRIGHT: (C)2013,JPO&INPIT【課題】野菜又は果実等の食材を、人体に有害な物質を一切使用せずに短時間処理するだけで、食材の細菌数を極端に低減又は滅菌する。【解決手段】野菜又は果実等の食材を、酸化カルシウム又は水酸化カルシウムの水溶液中に浸漬し、かつ同水溶液中に平均粒径が20~60μmの微細気泡を供給し、食材に前記飽和水溶液と前記微細気泡を5~20分間接触せしめる。【選択図】 図1
