The invention discloses an industrial method for producing tomato red by using tomato peel residues. The method comprises the following process steps of: (1) performing hydrocyclone separation on the tomato peel residues containing tomato seeds to obtain tomato peel, wherein the seed content of dried tomato peel is below 0.3 percent by weight; (2) smashing the tomato peel, and adjusting into tomato peel paste with 50-55 percent by weight of water; (3) extracting the tomato peel paste with an organic solvent, and separating to obtain an extracting solution, wherein the organic solvent is n-hexane, No.6 light petrol and/or petroleum ether; and (4) concentrating and deodorizing the extracting solution to obtain tomato red. Due to the adoption of the method, high-quality natural tomato red can be obtained; and the method has the advantages of simple process, short flow, small loss, high yield, low comprehensive cost, good product quality and easiness for realizing continuous industrial production.
