PROBLEM TO BE SOLVED: To produce a processed wheat food safe to a patient of cereal allergy by a sitologically allowable means by reacting a water-added wheat flour with a specific proteinase under neutral condition to decrease the allergen content of the wheat flour. SOLUTION: Wheat flour mixed with water or an aqueous solution of ethanol is reacted with a sitologically allowable proteinase having high collagenase-like activity under neutral condition. The enzyme preferably has a low amylase activity in addition to high collagenase-like activity and is most preferably bromelain. Preferably, 1 pt. of wheat flour is incorporated with 0.1-10 pts. of water or an aqueous solution of ethanol having a concentration of <=20% and reacted with 0.1-5wt.% (based on the wheat flour) of a proteinase. The present process gives a wheat having decreased allergen content and containing inactivated wheat allergen epidope, etc., having the amino acid sequence expressed by the formula. |
