Apple juice inoculated with alicyclobacillus acidoterrestris was treated with microwave at different power and time, and the efficacy of microwave against alicyclobacillus acidoterrestris was investigated. The results showed that alicyclobacillus acidoterrestris quantity decreased with microwave enhancement or time extension. When juice was treated with microwave at higher than 720 W and for longer than 40 seconds, the alicyclobacillus acidoterrestris of apple juice might effectively be prevented. Microwave treatment changed microbial morphology and destroyed cell membrane permeability, and this was one probable reason that led alicyclobacillus acidoterrestris to death.
