Abstract Food allergies affect an estimated 3 to 4 of adults and up to 8 of children in developed western countries. Results from in vitro simulated gastric digestion studies with purified proteins are routinely used to assess the allergenic potential of novel food proteins. The digestion of purified proteins in simulated gastric fluid typically progresses in an exponential fashion allowing persistence to be quantified using pseudo-first-order rate constants or half lives. However the persistence of purified proteins in simulated gastric fluid is a poor predictor of the allergenic status of food proteins potentially due to food matrix effects that can be significant in vivo. The evaluation of the persistence of novel proteins in whole prepared food exposed to simulated gastric fluid may provide a more correlative result but such .
