Drying and crushing the tomato skin; uniformly mixing the crushed tomato peel with deionized water to obtain a tomato peel solution; heating the tomato skin solution for the first time, preserving heat, adding a proper amount of enzyme, stirring, carrying out enzymolysis, then carrying out secondary heating, and stopping enzymolysis; performing high-temperature sterilization on the tomato skin solution after enzymolysis; and adding ethanol into the sterilized solution, stirring until the solution is uniformly mixed, standing for 24-48 hours, centrifuging, washing, and freeze-drying to obtain the protein. The technological process is high in extraction efficiency, the quality of tomato skin protein is good, waste of tomato sauce production waste and pollution to the environment are reduced, comprehensive utilization of resources is achieved, and the concept of green development is met.
