Learn why an apple wax coating is used and whether it's safe to eat. Find out what it's made of and the best way to wash your apples before eating.
1 Answer
Apples have a natural wax coating to protect them from moisture loss and pests. This natural wax is safe to eat, and commercially sold apples may have an additional, food-grade wax coating that is also safe for consumption.
Detailed Explanation:
Apples naturally produce a waxy coating on their skin, primarily composed of cutin. This wax serves several crucial functions for the fruit. First, it acts as a barrier against water loss, preventing the apple from drying out and shriveling. Second, it provides a protective layer against pests and diseases, making it more difficult for insects and fungi to penetrate the skin.
Commercially grown apples often have this natural wax removed during the washing and cleaning process. To replace this lost protection and enhance the apple's appearance and shelf life, a food-grade wax is often applied. These waxes are typically made from carnauba wax, beeswax, or shellac, all of which are approved for use on food by regulatory agencies. These added waxes are also considered safe to eat in the small quantities present on apples.
While the wax is safe, some people prefer to remove it for aesthetic reasons or to reduce potential pesticide residue. Washing the apple thoroughly with warm water and a mild soap, or using a fruit and vegetable wash, can help remove the wax. Peeling the apple is also an effective way to remove the wax completely.
Pro Tip:
If you're concerned about the wax coating, choose organic apples. Organic apples are less likely to have added waxes, although they will still have their natural wax coating.
