Research Topics: Intervention technologies (chemical and physical treatments, including electrolysed water, new commercial sanitizers, ultrasound, and irradiation) to enhance the safety and quality of fresh and fresh-cut produce. We look into the interactions among sanitizing agents, produce, bacteria, and washing conditions in a post-harvest sanitizing operation. Specifically, we examine the effect of surface morphology and topology (as well as other surface characteristics) of produce on the adhesion and removal of pathogenic organisms to and from produce surfaces. We investigate how to optimize flow conditions (velocity/shear, agitation, flow pattern) to maximize the efficacy of a washing operation. Research effort is also placed on how to combine several intervention technologies to achieve a target inactivation of bacteria without compromising the quality of produce.
