Abstract Standardized, model solid foods were developed with varying initial hardness and breakdown rates during in vitro digestion. One class of model foods was based on the Standard American Diet, with strong and weak gel versions created by modulating pH. Another class was developed using whey protein hydrogels, with strong and weak gel versions produced by addition of pectin. The initial hardness of the model foods ranged from 6.2 ± 1.0 N (whey protein weak gel) to 56.2 ± 5.7 N (whey protein strong gel; p
