PROBLEM TO BE SOLVED: To provide a method for producing a carbonic acid-containing food product capable of providing a carbonic acid-containing food product such as a carbonated drink without using a pressure resistant container, a contained food product, and a straw.SOLUTION: Provided is a method for producing a carbonic acid-containing food product where a liquid or fluidity food sealed in a thin container composed of any of paper, resin, metal foil and a laminated material of one or more thereof, and containing organic acid or carbonate or hydrogen carbonate is incorporated with at least carbonate or hydrogen carbonate in the case the food includes organic acid and with at least organic acid in the case the food includes carbonate or hydrogen carbonate, and a water soluble solid or solution shaped carbonic acid generation agent generating carbon dioxide by being mixed with a food is added to the food in a state where the sealability of the container is released.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】耐圧性の容器を用いることなく炭酸飲料等の炭酸含有食品の提供を可能にする炭酸含有食品の製造方法、容器入り食品及びストローを提供する。【解決手段】紙、樹脂、金属箔及びこれらの1又は複数からなる積層材のいずれかにより構成される薄肉の容器に密封され、有機酸又は炭酸塩又は炭酸水素塩を含む液体状又は流動性の食品に、食品が有機酸を含む場合には少なくとも炭酸塩又は炭酸水素塩を、炭酸塩又は炭酸水素塩を含む場合には少なくとも有機酸を含み、食品と混合することにより炭酸ガスを発生する水溶性固体状又は溶液状の炭酸発生剤を、容器の密封性が解除された状態で食品に添加することを特徴とする炭酸含有食品の製造方法。【選択図】図1
