PROBLEM TO BE SOLVED: To provide a production method by which, while sufficiently obtaining a deactivation effect and a flocculation effect of allergen due to an allergen deactivation agent and a flocculant, a stable state can be maintained over a long period by suppressing self-flocculation of flocculant before use.SOLUTION: A production method of an allergy inhibition composition includes: a step of generating a polyacrylic acid salt dispersion liquid of obtaining a polyacrylic acid salt dispersion liquid in which a polyacrylic acid salt is dispersed in water and a step of dissolving inorganic salts of dissolving inorganic salts having protein astringent effect in polyacrylic acid salt dispersion liquid generated in the step of generating the polyacrylic acid salt dispersion liquid.SELECTED DRAWING: None【課題】アレルゲン失活剤を凝集剤とによってアレルゲンの失活効果及び凝集効果を十分に得ながら、使用前において凝集剤の自己凝集を抑制して長期間に亘って安定した状態を維持できる製造方法を提供する。【解決手段】アレルギー抑制組成物の製造方法は、ポリアクリル酸塩を水に分散させたポリアクリル酸塩分散液を得るポリアクリル酸塩分散液生成工程と、ポリアクリル酸塩分散液生成工程で生成されたポリアクリル酸塩分散液にタンパク質収斂効果を持つ無機塩類を溶解させる無機塩類溶解工程とを備える。【選択図】なし
