Approximately, 0.70 of soybean protein consists of the storage globulins glycinin and -conglycinin and both of these proteins have high molecular weights and have been shown to be allergenic in humans, laboratory and farm animals.
Furthermore, the antigenic determinants of glycinin and -conglycinin arecextremely resistant to digestion in the intestinal tract.
demonstrated that intact antigenic residues of glycinin and -conglycinin could be seen in intestinal samples from calves up to10 h after feeding.
concluded that important food allergens in humans such as -conglycinin were stable to digestion in vitro.
