摘要
食品杀菌的一项新技术—脉冲电场非热杀菌,可望作为传统热杀菌方法的一种合适的补充或取代方法,因此是项非常有前途的技术。食品能够使用脉冲电场在环境温度下或冷藏温度下用很短的时间进行杀菌,使食品的新鲜质量得到保存。虽然目前仍然存在着很多工程问题有待解决,但应用这种方法在实验室内已获得了成功,并正接近工业利用。
A new technology for pasteurization of foods- Pulsed Electric Field (PEF) Non-Thermal Pasteurization is a promising technology for the non-thermal pasteurization of foods and a sound complement or replacement to traditional thermal pasteurization. Foods can be pasteurized with pulsed electric fields at ambient or refrigerated temperatures for a short treatment time of seconds or less and the fresh-like quality is preserved.
Although applying pulsed electric fields to food pasteurization on a large scale presents many unresolved engineering challenges, pulsed electric fields used to food pasteurization is successful in laboratory tests and it is approaching to industry operation. This paper reviews pulsed electric fields and PEF bactericidal effect. Design of treatment chambers for high voltage pulsed electric field pasteurization and examples of PEF microbial inactivation in laboratory tests are presented.
