By microencapsulating the antioxidants in the peels before freeze-drying and grinding the peels into a powder, the scientists produced an organic, edible coating that blocks oxygen from reaching produce while also locking in the food’s naturally occurring moisture. The peels are antimicrobial, an essential factor in healthily preserving fresh-cut fruits. And, crucially, the coating also does not interfere with the taste, color, or general appearance of the produce.
It is estimated that 8-10 percent of global greenhouse gas emissions are associated with food that is not consumed, and a substantial portion of that waste comes as a result of foods turning bad before they can be eaten. A natural antioxidant, passion fruit peels are an overlooked material that could hold the key to extending the shelf life of food, thus reducing the amount that ends up in a landfill. A team of researchers from the University of Johannesburg has recently created a way to use peels as a healthy preservative for fresh fruits and vegetables.

Once used on an item, the antioxidant and antimicrobial qualities ensure that if a package is opened and closed multiple times, the strength of the coating remains intact. This also helps reduce spoilage from food that is not consumed in a single use. If kept in a cool, dark storage space, researchers predict that the powder could last up to six months at full strength.
Improving the way foods can be preserved sustainably would drastically help cut food waste. This is quite a good natural preservative that we can use.
