Method for extracting composite components with gastrointestinal tract protection function from peas and chickpeas

The invention discloses a method for extracting composite components with a gastrointestinal tract protection function from peas and chickpeas, and belongs to the technical field of food processing. The invention provides an extraction method of pea and chickpea composite components, and evaluates the protective effect of the pea and chickpea composite components on gastrointestinal tracts by establishing an ethanol-induced mouse acute gastric mucosal lesion model and a dextran sodium sulfate (DSS)-induced mouse ulcerative colitis model. The pea and chickpea composite component is obtained by grinding and sieving peas and chickpeas, performing water extraction and alcohol precipitation, and performing JK008 static adsorption and purification, and the main components are polysaccharides and proteins. The pea and chickpea composite component extracted by the invention has the effect of protecting gastric mucosa, can effectively reduce acute gastric mucosa injury caused by ethanol, and also can play the roles of
