PROBLEM TO BE SOLVED: To provide an agent for suppressing gas generation during storage of an effervescent composition, a method for producing an effervescent composition using the agent, and an effervescent composition. SOLUTION: An agent containing erythritol as an active ingredient and suppressing gas generation during storage of an effervescent composition, a method for producing an effervescent composition using the same, and an effervescent composition. According to the present invention, a foaming composition in which gas generation during storage is suppressed can be produced by a simple and highly versatile method. As a result, even after the process of distribution and storage, expansion and deformation of containers and packaging and reduction of gas generation during use are suppressed, and foaming compositions with relatively maintained product quality are supplied to the market. can do. [Selection diagram] Fig. 3【課題】 発泡性組成物の保存時の気体発生を抑制する剤、これを用いる発泡性組成物の製造方法および発泡性組成物を提供する。【解決手段】 エリスリトールを有効成分とする、発泡性組成物の保存時の気体発生を抑制する剤、これを用いる発泡性組成物の製造方法および発泡性組成物。本発明によれば、簡便で汎用性の高い方法で、保存時の気体発生を抑制した発泡性組成物を製造することができる。これにより、流通や保管等の過程を経ても、容器・包装の膨張・変形や使用時の気体発生の低減等が抑制されて、製品品質が比較的維持された発泡性組成物を市場に供給することができる。【選択図】 図３
