Fall has arrived and apple season is finally upon us. Did you know that apples produce their own wax coating? This wax is commonly referred to as “bloom” and appears as a white coating on the apples.
This natural coating helps to preserve the fruit during the growing process .
The bloom, or natural wax coating is usually removed when the apples are washed during the picking and packaging process. After the picking process, some apples are then coated with a food grade wax which helps preserve the fruit to help lengthen the shelf life. The food grade wax used to coat apples, as well as other fruits and vegetables, is typically a type of emulsion made with carnauba wax. The carnauba wax gives apples a shiny appearance.
This type of food grade wax is indigestible by humans and would simply pass through your system untouched, similar to the way chewing gum would if accidentally swallowed.
