PROBLEM TO BE SOLVED: To provide a quick-cooking rice porridge-like food base for preparing a rice porridge-like food which easily achieves superior flavor, stable physical properties and superior mastication and swallowing characteristics only by adding water or hot water and simply stirring and a quick-cooking rice porridge-like food prepared by using the quick-cooking rice porridge-like food base.SOLUTION: This invention includes the quick-cooking rice porridge-like food base, the method of producing the quick-cooking rice porridge-like food using the quick-cooking rice porridge-like food base, and the quick-cooking rice porridge-like food produced by the method for producing the quick-cooking rice porridge-like food. The quick-cooking rice porridge-like food base contains a low-viscosity gelatinized medium-grain rice product whose viscosity is adjusted in the range of 50-600 mPa when 10 pts.wt. of water is added to 1 pt.wt. of medium-grain rice powder as a main component, and achieves the flavor of the time when the food is prepared for eating, and excellent stable physical properties and excellent mastication and swallowing properties only by pouring water or hot water and simply stirring. The quick-cooking rice porridge-like food using the quick-cooking rice porridge-like food base is produced by a physical viscosity reducing process by shearing or a molecule reducing process using enzymes, acid or an oxidizing agent. The quick-cooking rice porridge-like food is excellent in the mastication/swallowing characteristics, and can be provided for a person with disability in mastication. Further, the hardness, physical properties and calories of the quick-cooking rice porridge-like food can be adjusted, and the viscosity of the food is not changed with time while eating.COPYRIGHT: (C)2012,JPO&INPIT【課題】水或いはお湯を加え簡単に攪拌するだけで容易に優れた食味と物性の安定性及び優れた咀嚼・嚥下特性を付与した粥状食品を調製できる即席粥状食品の素及び該即席粥状食品の素を用いて調製した即席粥状食品を提供すること。【解決手段】せん断による物理的低粘度化処理、又は酵素、酸或いは酸化剤による低分子化処理により、うるち米アルファ粉1重量部に水10重
