摘要: 研究了不同功率、时间的超声波处理鲜乳后的杀菌效果。结果表明,经600W,3min超声波处理的原料乳,杀菌率达93%。并研究了超声波结合巴氏杀菌技术对鲜乳处理后,4℃贮藏条件下牛乳品质变化情况。结果表明,经600W,3min超声波处理的原料乳结合63℃,30min的热处理后,乳品质保持最好,4℃贮藏条件下贮藏期达16d左右。

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 ℃.
