Abstract

The invention discloses an in vitro simulated digestion box, which comprises sequentially connected stomach digestion parts, small intestine digestion parts and large intestine digestion parts; the stomach digestion parts are riveted and connected by an upper assembly and a lower assembly; liquid inlet, stomach digestive juice inlet, sampling port and stomach digestion sample outlet; the small intestine digestion part is connected by riveting of the first component and the second component, and the small intestine digestion part includes a sample inlet, a stomach digestion sample inlet, an intestinal digestion sample Outlet and intestinal digestion sample sampling port, the large intestine digestion part is riveted connection by the third component and the fourth component, and the large intestine digestion part includes an intestinal digestion sample inlet, a cell culture medium inlet, a digestion and absorption sample outlet, and a metabolic digestion sample outlet and polycarbonate film. The in vitro simulated digestion box has a stable structure and good reproducibility; the equipment is simple and the conditions are easy to control.

Description

technical field [0001] The invention belongs to the technical field of in vitro complete digestive tract simulation, and in particular relates to an in vitro simulated digestion box, which reflects the digestion of soluble nutrients by the human digestive tract. Background technique [0002] The ingredients in food are complex. In the process of digestion, different nutritional ingredients have different changes. Different nutritional ingredients have different mechanisms for producing physiological activities. The mechanism by which physiological activity is produced will change. Polyphenols, carotenoids, vitamins and polysaccharides will all change during digestion, thereby affecting the expression of their physiological activities (Food Chemistry, 2006, 102(3), 865-874; FoodHydrocolloids, 2016, 58, 171-178; British Food Journal, 2008 110(3), 296-309; Journal of Agricultural & Food Chemistry, 2006, 54(23), 8749-8755). [0003] In order to detect the changes of nutrients ...
