Chlorination: Total chlorine up to 200 ppm is currcently allowed in food processing runse water to assure potability. 50 to 100 ppm is, however, usually sufficient. Maintaining these levels ofchlorine at all times is critical to reduce microbial populations on a fresh-cut produce and reduce cross contamination in the rinse water system. Chlorine is injected into the rinse water system as either a gas or a liquid (Sodium or Calcium Hypochlorite). Careful monitoring and control of free chlorine levels during processing is criticaL Chlorine test kits or biological oxygen demand () meters should be used to monitor and adjust chlorine levels. Excessively high concentrations of chlorine will damage fresh-cut produce and reduce shelf life as well as cause off flavors and odors.
