In vitro method modeling the consistency generated in vivo by food during the digestion thereof

摘要

The present invention relates to an in vitro method modeling and measuring the consistency generated in vivo by a food during the digestion thereof. The method includes the steps of grinding the food to reproduce the mechanical breakdown performed during chewing, mixing under stirring of the ground food with a solution modeling gastric fluid in a reactor vessel coupled with a rheometer for a time corresponding to gastric digestion, and adjustment under stirring of the reaction mixture to model intestinal digestion conditions for a time corresponding to intestinal digestion, wherein the rheometer is provided with a stirrer used to homogenize the mixture and measure the viscosity and/or the viscoelasticity thereof.
