Original title: INFOGEST static in vitro simulation of gastrointestinal food digestion
Labs can simulate how food is digested, but different conditions make their results hard to compare. INFOGEST 2.0 gives researchers a shared protocol using standard lab equipment and conditions based on physiological data. It moves a food sample through oral, stomach, and intestinal stages, then researchers can measure digestion products and micronutrient release. The method keeps the fluid ratios and pH constant at each stage, so it cannot show how digestion changes over time.
Imagine a school using one shared recipe to compare how different students cook the same meal. If each student changes the heat and ingredients in their own way, the results are hard to compare. In this paper, the shared recipe is the digestion protocol, and the meal moves through set mouth, stomach, and intestine stages. The fixed conditions make comparisons easier, but they cannot show how the process changes moment by moment.
Researchers studying how food structure and composition affect health have used digestion simulations with very different conditions, making results hard to compare. This protocol gives labs a shared method based on physiological data, while making clear that it cannot track digestion over time.
The abstract says the method is static: it keeps meal-to-fluid ratios constant and uses a constant pH at each digestion stage, so it is not suitable for simulating digestion kinetics. It describes endpoint analysis, but does not report how closely results match digestion in living people or how well the method performs across different foods.
