Preparation method of antioxidant reengineered rice

The invention discloses a preparation method of antioxidant reengineered rice. Brown rice is taken as a raw material and subjected to superfine crushing to form fine powder, the fine powder is mixed with soy protein isolate, soybean oligopeptide and a blueberry extract in proportion, the mixture is subjected to high-humidity extrusion texturizing forming with a twin-screw extruder, and drying, dust removal and packaging are performed. The reengineered rice with the antioxidant healthcare function has the effects of balancing diet and guaranteeing nutrition intake of eaters, rice polypeptides as well as the added soybean oligopeptide and the blueberry extract can play the antioxidant function, lipid oxidation of the reengineered rice can be prevented, the expiration date of the reengineered rice is prolonged, and the reengineered rice can reduce the level of free radicals in bodies and help the bodies to resist diseases.
