Current in vitro digestion systems for understanding food digestion in human upper gastrointestinal tract

摘要

Background: Food digestion rate and location within the gastrointestinal (GI) tract are important for human health. Ideally, food digestion studies should be performed in vivo but this is not always technically, ethically and financially possible. Thus, various in vitro digestion systems have been developed, from static mono-compartmental to dynamic multi-compartmental models, to simulate food digestive behaviors within the GI tract.
