PROBLEM TO BE SOLVED: To provide a method for producing allergen-reduced grain in which the allergen content of allergen-containing grains is easily reduced, which was considered to be difficult in the prior art.MEANS FOR SOLVING THE PROBLEM: Allergen containing grains such as soybeans and peanuts are brought into contact with superheated steam at a temperature of 250°C to 620°C for 10 minutes to 1 minute. Powder of allergen-containing grains is brought into contact with superheated steam at a temperature of 250°C to 620°C for 20 seconds to 0.3 seconds. Examples of allergen-containing grains include soba, wheat, peanut, soybean, walnut, or rice.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】従来技術では至難とされていたアレルゲン含有穀物のアレルゲン含有量を容易に低減して、アレルゲン低減化穀物を製造する。【解決方法】 大豆、落花生等のアレルゲン含有穀物を温度250℃~620℃の過熱水蒸気に10分間~1分間接触させる。 アレルゲン含有穀物の粉体は、温度250℃~620℃の過熱水蒸気に20秒間~0.3秒間接触させる アレルゲン含有穀物としては、そば、麦、落花生、大豆、クルミ又は米が挙げられる。【選択図】なし
