Abstract: Sterilization of liquid food crude beer with magnetic inspired pul se electromagnetic field was studied. Results showed that sterilization effect str engthened with the magnetic field intensity and pulse numbers. When magnetic fi eld intensity reached higher than 2.53T and pulse number more than10, or magnet i c field intensity more than 2.11T and pulse number more than 30, the sum of su r viving bacillus in crude beer was less than 50/ml.The results satisfied the bu s iness demand.Sterilization mechanism with magnetic inspired pulse electromagne ti c field was simply analyzed.

Key words: pulse magnetic field, sterilization, crude beer, mechanism
