The allergenic potential of food may be reduced or increased by manufa
cture and processing. The first part of this overview is devoted to th
e influence of processing on the allergenic potential of foods. In the
second part, model studies on the effect of heating on the stability
of soybean allergens and on the allergenic potential of commercial soy
products are presented. Virtually all conventional methods of food pr
ocessing, except for complete separation of the protein fraction, leav
e a certain rest allergenicity for allergic individuals.
