A method for the production of hydrolyzed allergens from allergens comprising the steps of:a) extracting a source of allergens comprising allergenic proteins to form an extract,b) purifying the extract to remove non-protein components to form a purified extract,c) denaturing the purified extract with a first denaturing agent to form a purified denatured extract,d) refining the purified denatured extract to remove impurities to form a refined denatured extract,e) denaturing the refined denatured extract with a second denaturing agent to form denatured allergen mixture, andf) hydrolyzing the denatured allergen mixture to form the hydrolyzed allergens.
