Effect of liquid-state fermentation on potential soy allergenicity was studied.
Sandwich ELISA with monoclonal anti-Glym5 antibodies (mAbs) was used.
Western blot was performed using mouse mAbs and sera from soy sensitive individuals.
Fermentation with Lactobacillus helveticus reduced IgE-binding up to 100%.
Beany and bitter off-flavors were considerably reduced following fermentation.
