Title: Natural antimicrobial plant wash formulation


Invention: The invention is an antimicrobial wash for use in post-harvest treatment of produce. The antimicrobial plant wash is a blend of essential oils and plant extracts that are Generally Recognized As Safe ingredients (GRAS).


Background: Post-harvest treatment is currently conducted with chemical sanitizers to control microbial contamination on organic produce. Chlorine is a common chemical sanitizer used, but it is known to form carcinogenic compounds such as trihalomethane. The invention utlizes energy and environmentally friendly plant antimicrobials for use in the organic fresh produce industry.




-Post-harvest treatment washing for organic produce 


-Natural, antimicrobial personal care products (liquid soap, body wash, etc.)




-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


-Plant antimicrobials can continue to inhibit growth of microorganisms during storage


-Wash liquids can be reused to lower costs, but still maintain efficacy against microorganisms


-Plant compounds provide health benefits such as reduction in cholesterol, anti-oxidative, anti-diuretic, and anti-carcinogenic activities


-Plant compounds can also be used as unique flavoring for foods
