Definition

Laboratory protocols that replicate key physicochemical and enzymatic conditions of the human digestive tract (oral, gastric, small‑intestinal phases, and optionally colonic fermentation) under controlled pH, transit time, enzyme composition and mixing to study food matrix breakdown, nutrient release and bioaccessibility; these simulations model digestive exposure but do not directly measure in vi
