Researchers from the U.S. Department of Agriculture (USDA) recently reported the development of a natural, edible food coating to help prevent bacteria such as E. coli from infecting fresh produce.
The report -- published in the Nov. 29 issue of the Journal of Food and Agricultural Chemistry -- found that food coatings made from apple puree containing a natural antimicrobial compound made from oregano, lemongrass or cinnamon oil effectively killed E. coli bacteria.
Researchers found that apple puree mixed with oregano oil was the most effective, killing more than 50 percent of E. coli microorganisms within three minutes. The apple puree coatings also contain sticky fats and sugars that allow them to stick to the surface of fruits and vegetables more effectively than water-based conventional antimicrobial washes.
