Fruit Wax Coverings
Most fruit farmers and manufacturers cover their fruits in a coating of wax to help preserve them. In order to do this they first remove the natural wax that originally covers the fruit through washing. They then coat fruits such as apples and oranges in a petroleum-based wax.
Although these manufacturers claim that the wax is needed to preserve the fruit and prevent fungus and bacteria from building up on them, it is also known that the wax is used to add coloring and to give the fruit a more favorable appearance. This has led many to question the necessity of this wax use, with people wondering whether it is needed to keep fruit fresh or just used to make us buy more of it.
Fruit Wax Ingredients
There has been a lot of controversy surrounding the ingredients that are used to make this wax. Since it is technically not considered a food ingredient, companies are not required to disclose exactly what the wax is made of.
Most conventional wax coatings contain preservatives and fungicides. Sometimes they can also contain artificial coloring and dyes meant to improve the appearance of wax. Many dyes commonly used in food products have been linked to an increased risk of developing cancer.
