Application of Pulsed Power Technology in Nonthermal Food Processing and System Optimization

Abstract

A pilot plant scale pulsed electric field (PEF) continuous processing system was integrated with an aseptic packaging machine to test and demonstrate the efficacy of PEF technology as a non-thermal food processing method. Major components includes a 40,000 V/17 MW(sub-p) high voltage pulse generator and a set of multiple stages co-field PEF treatment chambers. Fluid foods could be processed at 50 - 150 I..At flow rate and packed aseptically into 200 ml plastic cup containers. System design was discussed and the microbial inactivation effect of this integrated PEF system was validated by microbially-enhanced orange juice (MEOJ) tests. The studies on PEF treated, aseptically packaged fresh orange juice indicated that this technology has the potential to extend the product shelf life.
