This research tested six common culinary essential oils to see if they could prevent fungi from growing on bananas after harvest. Scientists identified four types of harmful fungi that cause banana rot and tested how well oregano, rosemary, clove, thyme, cinnamon, and basil oils could stop them. The results showed that cinnamon, clove, and oregano oils were most effective at stopping fungal growth, offering a natural alternative to chemical fungicides that consumers want to avoid.
