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