According to the method for preparing the tomato beverage from the tomato sauce disclosed by the invention, two groups of tomato stabilizers are provided, and the stabilizing effect of each group is relatively good. The tomato beverage is prepared by the steps of grinding, homogenizing, filling and sterilizing. The beverage comprises the following components: 3% of tomato sauce, 4% of white granulated sugar, 0.1% of citric acid and 0.03% of compound stabilizer (0.02% of CMCFH6 and 0.01% of pectin). The tomato beverage compound stabilizer has advantages that tomato beverage compound stabilizerhas excellent stability, and tomato beverage prepared from tomato beverage compound stabilizer has excellent stability, a large number of experiments prove that the compound stabilizer is good in compounding effect, and sensory indexes, physicochemical indexes and microbial indexes are not changed after the beverage is placed for 90 days.
