PEPTIC DIGESTIBILITY OF COWS MEAT PROTEIN S

Peptic digestibility of bovine beta-lactoglobulin in the presence or a bsence of grilled cow's meat homogenate was analyzed by 16% SDS-polyac rylamide gel electrophoresis and Western blot analysis with anti-bovin e beta-lactoglobulin. Most of proteins in the grilled cow's meat homog enate were rapidly digested by pepsin. beta-Lactoglobulin, a major cow 's milk allergen, was resistant to the peptic digestion, but the pepti c digestibility of beta-lactoglobulin was promoted in the presence of grilled cow's meat homogenate. These results suggest that a low level of antigenic polypeptides may remain after peptic digestion of grilled cow's meat, and cow's meat intake may improve peptic digestibility of indigestible proteins in the stomach.
