Title: Study on Sterilization of Fresh Milk with Ultrasonic Technology
Abstract: Fresh milk was treated by different ultrasonic powers and time to study the bactericidal effect. Results indicated that,treating fresh milk with ultrasonic of 600 W for 3 min,the sterilization rate reachs 93%. Treated with the combination of ultrasonic with heat sterilization,the quality of milk stored under 4 ℃ was also studied. Results showed that,treated with ultrasonic of 600 W for 3 min and then heated at 63 ℃ for 30 min,the quality of milk is better than others. The storage period of the treated milk can be prolonged to about 16 days under 4 ℃.
