PROBLEM TO BE SOLVED: To provide food in which viscosities of moistures in the surface or the vicinity of the surface and also in the inner part are uniformly increased to reduce water content separated by chewing or to eliminate the separation of the moisture, which is a food material ensuring high safety for a person who has difficulty in chewing/swallowing function to decrease the risk of aspiration: and to provide a method for producing the food material by which such food material can be economically, easily and inexpensively prepared in a short time.SOLUTION: The method for producing the food comprises the following process: a process of making an unsolvated thickener and/or sticky-transformation dispersion solution where sticky substance-producing microorganisms are dispersed adhere to the surface of the food material to prepare sticky-transformation dispersion solution-adhering food material and a process of depressurizing and/or pressurizing the sticky-transformation dispersion solution-adhering food material to perform pressurization treatment so as to make the inner part of the food material uniformly contain the unsolvated thickener and/or the sticky substance-producing microorganisms.COPYRIGHT: (C)2008,JPO&INPIT【課題】本来の形状、色、味、香り、食感、栄養成分を保持しながら、表面や表面近傍に含まれる水分に留まらず、内部に含まれる水分についてもその粘度を均一に上昇させ、咀嚼により分離する水分量の低減を図り若しくは、水分の分離を排除できる食品を提供し、咀嚼・嚥下が困難な者にとって、誤嚥を抑制することができる安全性の高い食材を提供する。このような食材を短時間で、無駄なく、簡単且つ安価に調製することができる食品の製造方法を提供する。【解決手段】未溶媒和状態の増粘剤および/または粘性物質を産生する微生物を分散した粘性化用分散液を食材の表面に付着させ粘性化用分散液付着食材を調製する工程と、粘性化用分散液付着食材を減圧および/または加圧して圧力処理を行ない、未溶媒和状態の増粘剤および/または粘性物質を産生する微生物を食材の内部に均一に含有させる工程とを有する。【選択図】なし
