About

Reusability of Antimicrobial Plant Washes

Tech ID: UA16-245

Invention:
University of Arizona researchers have developed plant compounds that can be used multiple times in wash water without the loss of antimicrobial efficacy.

Background:
Post-harvest treatment is currently conducted with chemical sanitizers to control microbial contamination on organic produce. The wash waters could be reused up to five times for washing organic leafy greens. These wash waters provide an alternative sanitization option.

Key Benefits

Plant extracts and essential oils do not corrode washing equipment unlike chlorine.
Plant antimicrobials are more biodegradable.
Plant antimicrobials are more stable than chemical sanitizers.
Wash liquids can be reused to lower costs, but still maintain efficacy against microorganisms.
Plant compounds have health benefits such as reduction in cholesterol, anti-oxidative, anti-diuretic, and anti-carcinogenic activities.

Applications

Post-harvest treatment washing of organic produce.
