CBD could be a useful antimicrobial treatment for fresh produce, according to a study by researchers at the University of South Florida’s Food Quality Laboratory, Department of Cell Biology, Microbiology and Molecular Biology, published in the journal Postharvest Biology and Technology.

The researchers applied CBD oil to fresh fruit immediately after harvest, followed by storage at 1°C for eight days and 10°C for another 8 days. The strawberries treated with CBD were evaluated for visual quality and microbial load before and during storage and rated based on how they looked.

Results from this study, the researchers said, showed CBD oil “was effective at maintaining the visual appearance of strawberries, above the minimum threshold of a visual rating score of 3, compared to the fruit that was not treated.” The oil inhibited both yeast and mold growth on the fruit and the treated strawberries “had better overall quality compared to non-tread fruit,” the study authors said.
