Preparation method of peony plant-based protein meat with antioxidant function

The invention relates to a preparation method of peony plant-based protein meat. The method comprises the following steps: taking peony seed meal protein as a raw material, adding proteolytic enzyme into the separated peony seed meal protein, and controlling the adding type, sequence and proportion of the proteolytic enzyme to obtain hydrolyzed peony seed protein peptide with high oxidation resistance; and then producing a mixture of peony plant-based protein and protein peptide by adopting a high-moisture extrusion method, and then cooling in a slender pipe to rearrange and crosslink protein molecules to finally form an obvious fiber structure. The high-antioxidant functional peony seed protein peptide powder prepared by the method disclosed by the invention can be used as a food additive raw material or used in the cosmetic industry, so that the comprehensive utilization rate of peony seed processing byproducts is greatly improved, and the added value of the product is improved. 本发明涉及一种牡丹植物基蛋白肉的制备方法，本发明以牡丹籽
