Title: Re-Usability of Plant Antimicrobial Washes Against Salmonella Newport on Organic Romaine Lettuce and Baby Spinach

Invention: This technology demonstrates the ability of edible washes to inactivate S. Newport on organic leafy greens, specifically showing that the effectiveness of these compounds is not diminished after multiple washings. Since the active molecules are volatile, the advantage of using edible washes in salad bags is that the films can release vapors constantly into the surrounding environment, thus maintaining constant activity over time during storage. In addition to their antimicrobial properties, these washes contain numerous beneficial nutritional and bioactive components that may also benefit human health.

Application: These antimicrobial washes can be used by the food industry to inactivate Salmonella in organic leafy greens, and they can be reused to reduce the cost of cleaning large amounts of produce.
