The tomato peel is used for extracting lycopene and/or used as a feed additive; the tomato seed is used for preparing tomato seed oil and/or used as a feed additive; the tomato juice containing pulp is separated to obtain clear juice and wet pomace; the clear juice can be prepared into concentrated clear tomato juice or soluble solid powder; the wet pomace is used for extracting lycopene after removing water and alcohol-soluble substances with low-carbon alcohol; and the pomace after the extraction of lycopene is used for producing tomato fiber. During the lycopene extracting process, the third time of leaching uses pure solvent, the second time of leaching uses the leaching solution in the third time of leaching, and the first time of leaching uses the leaching solution in the second time of leaching, and the leaching solution obtained in the first time of leaching is frozen to separate out lycopene crystal with purity of above 80% after recrystallization. The inventive method has advantages of effective resource utilization, low production cost, and applicability for large scale production.
