Zusammenfassung:The invention relates to the technical field of dairy product processing, and discloses a low-protein denaturation-rate milk sterilization method which comprises the following steps: pre-sterilizing milk at 62-68 DEG C for 15-20 seconds; the pre-sterilized milk is detected, and if the detection result does not reach the index, standardization is carried out until the index is reached; preheating the milk reaching the index to 60-65 DEG C; the preheated milk is subjected to flash sterilization, the inlet heat source temperature is controlled to range from 70 DEG C to 85 DEG C, the vacuum degree ranges from-0.6 MPa to 0.8 MPa, the center temperature of the milk does not exceed 65 DEG C, and the flash sterilization time ranges from 10 s to 15 s; and cooling the milk subjected to secondary sterilization. Pre-sterilization and standardization are performed before secondary sterilization, and flash sterilization and pasteurization are combined during secondary sterilization, so that the sterilization effect can be
