Carrier for intestinal targeting and ROS (reactive oxygen species) removal as well as preparation method and application of carrier

The invention belongs to the technical field of functional food development and biological medicine, and relates to an intestinal targeting and ROS (reactive oxygen species) removal carrier as well as a preparation method and application thereof. The invention provides a preparation method of a carrier for intestinal targeting and ROS (reactive oxygen species) removal, which comprises the following steps: heating and dissolving low-ester pectin, adding gelatin and glycerol to prepare a mixed solution, adding microalgae into the mixed solution, mixing to obtain a film-forming solution, and preparing the carrier from the film-forming solution. The activated probiotics and the film forming solution are mixed to prepare the ROS removal type edible film loaded with the probiotics. The ROS removal type edible film can effectively resist the adverse environment of the stomach to the probiotics, so that the probiotics smoothly reach the intestinal tract to play a role. 本发明属于功能食品开发及生物医药技术领域，涉及一种肠靶向和ROS清除的载体及其制备方法与应用。本
