The tomato sour soup product rich in cis-lycopene is prepared by the following method: uniformly mixing tomato sour soup with grease, stirring on an electric furnace of 1000W or in a water bath kettle at 110-120 DEG C for hot processing for 45 minutes to convert trans-lycopene into cis-lycopene, the whole operation can be completed within 2-3 hours, the production process is greatly simplified, the production cost is reduced, and the tomato sour soup product rich in cis-lycopene is suitable for industrial production. Operation is easy and convenient, and environmental pollution is avoided; the isomerization production efficiency is greatly improved, and the contrast advantage is obvious; the tomato sour soup is wide in raw material source, easy to obtain and low in cost, plays an important role in strengthening functions of traditional tomato sour soup and has huge market potential.
