Abstract: The paper made a main research about the heat-resisting characteristic of cecropin-XJ isolated from Xinjiang Silkworm to find its, minimum concentration to kill microorganism, and its solubility and effects on restraining microorganism in different pHs. Furthermore, adding it into tomato juice as processing ingredients by orthogonal test to obtain the optimum conditions of processing, the results showed that it enhances the sterilization strength and improves the quality of tomato juice and provides guidance for industrial production.
