Abstract: The decomposition of penicillinin in milk by ultrasonic wave and by ultrasonic wave cooperated with vitamin C was repectively investigated in this study. Results showed that the antibiotics can be better decomposed by the cooperation of ultrasonic wave and vitamin C. The optimal decomposition efficiency can be accessed under the following the conditions of cell grinder duty cycle 60, output powder 60%, process time 8 minutes, vitamin C concentration 0.1% and penicillin content no higher than 1.0 unit.

Key words: penicillin, vitamin C, milk, ultrasonic wave, decomposition
