in process mill starch slurry as a means to progressively decontaminate intermediate and final starch products as well as to remove residual recontaminating biofilm from downstream process surfaces of the maize or corn starch mill equipment infrastructure fig1 provides a graphic representation of the anolyte antimicrobial efficacy results showing the significant reduction of microbial contaminants between the two sampling days day 1 and day 56 as well as the consequential reduction in microbial contamination when the anolyte was added to the slurry after the point of supply from the wet mill this effect was consistently associated with the strategic intervention with anolyte throughout the overall process flow anolyte in the equivalent dilutions and at the prescribed intervention points as detailed in example 1 was added to starch mill slurry and the final commercial product was assessed for compliance with internal microbial specifications consistent and continuous addition of anolyte solutions to in process mill starch slurry results in a progressive reduction of microbial contamination of finished product with a reliable and predictable attainment of the highest grade of commercial product based on the level of microbial contaminants correlation between changes in orp oxidation reduction potential ph and electrical conductivity measurements as a result of progressive dilution and antimicrobial efficacy anolyte was generated from two different salt types i e sodium chloride and sodium bicarbonate orp u2267 u2212 900 mv and ph 7 u00b1 0 5 and was diluted with a variety of tap water distilled water and deionized water the orp was measured with a commercial redox probe that had been.
