Treatment System and Method for Preserving Fresh Produce

This invention describes a system and method to preserve fresh produce by washing it in two stages. First, the produce is cleaned in an alkaline hydrogen peroxide solution, which can specifically include sodium carbonate or sodium percarbonate. Then, it's washed again in a solution containing an anti-microbial agent combined with an acid activator.

Why it matters: The cost and precision of automated chemical dosing and pH control systems have significantly improved since 2007, making this multi-stage chemical wash more practical for food preservation.
