Researchers developed a special edible coating made from konjac glucomannan and basil essential oil that can be applied to oranges to keep them fresh longer. The coating acts as a protective barrier that slows down moisture loss and microbial growth while allowing the fruit to breathe. When applied to Mandarin oranges, this coating extended their shelf life by 8 days, kept them firmer, and reduced spoilage compared to uncoated oranges.
