Investigation and Validation of Chlorine-Based Fresh Produce Washing Procedures Using Novel Experimental Platforms

Objective 1. Fabrication of chlorine sensing chip to mimic fresh-cut and cracks of produce. We will develop a polymeric sensor chip with separable design, rapid chlorine indicating capacity, and adjustable, localized chlorine demand.Objective 2. Investigation on the sanitization process using the sensing chip under simulated washing conditions. We will investigate bacterial attachment, chlorine availability, and sanitizing efficacy under various conditions mimicking the fresh produce washing process, using the novel experimental platform.
