The invention relates to a processing technology for improving the lycopene content in a tomato product, which comprises the following steps that: the synthesized quantity of lycopene in tomato homogenate is improved; at the atmospheric temperature, the cherry tomato fruit at the firm ripe stage is capped, washed and juiced, the juice is collected, and citrus peels inside a juicer filter is mixed with the juice after being minced so as to obtain the tomato homogenate. 3.0 percent of glucose and 2.5 percent of sodium glutamate are added into the tomato homogenate to be processed for 60 minutes at a constant temperature of 25 DEG C. Different tomato products with high lycopene content can be prepared by adopting the processed tomato homogenate as raw material. (1) The lycopene content in tomato ketchup which is prepared by the processed tomato homogenate is improved by 39.8 percent, and the production process of the tomato ketchup is: 0.25 percent of carrageenan and 2.0 percent of sucrose are added into the processed tomato homogenate to be heated and concentrated until the content of the solid substances reaches 35 percent, the tomato ketchup is covered and sealed after being canned in a glass bottle to be sterilized in the hot water with the temperature of 95 DEG C for 15 minutes. (2) The lycopene content of the tomato haw sheet prepared by the processed tomato homogenate is improved by 21.4 percent, and the production process of the tomato haw sheet is that: 40 percent of white granulated sugar, 0.1 percent of lemon acid and 4 percent of starch are added into the processed tomato homogenate, the thickness of the sheet is 2 mm, and the haw sheet is baked for 11 hours at the temperature of 60 DEG C.
