The assay consists of two bioreactors, one containing pepsin and the other containing trypsin, chymotrypsin and intestinal mucosa peptidases. The fraction of the peptide bonds hydrolyzed during an extent of hydrolysis assay was correlated with independent in vivo determinations of the digestibilities. A correlation coefficient of 0.80 was obtained. The derived linear regression equation can be used to predict digestibility. The method is sensitive to structural modification of protein, as for example, those caused by effects of heat treatment.}, number={1}, journal={PLANT FOODS FOR HUMAN NUTRITION}, author={THRESHER, WC and SWAISGOOD, HE and CATIGNANI, GL}, year={1989}, month={Mar}, pages={59–65} }
