Experts Debunk Social Media Claims About Harmful Apple Wax

Concerns circulating on social media that the wax coating on apples is harmful have been addressed by food safety experts and medical professionals, who state that the wax is safe to consume and serves a crucial purpose in preserving the fruit.

The wax applied to apples is a food-grade substance, approved by regulatory bodies like the U.S. Food and Drug Administration (FDA) and international organizations. These waxes, often derived from natural sources such as shellac and carnauba wax, replace the natural coating, or bloom, that fruits possess. This natural coating helps retain moisture and protect against microorganisms but is often removed during the harvesting and washing process.

Carla L. Schwan, an assistant professor and food safety extension specialist at the University of Georgia, explained that waxing is a standard practice implemented globally to maintain the quality of apples, especially during long-term storage. The coating helps prevent moisture loss, shrinkage, and softening, thereby reducing spoilage. Without this protective layer, more than a third of apples could spoil before reaching consumers.

Experts emphasize that the waxes used are considered Generally Recognized as Safe (GRAS) by the FDA. Panels of scientists from the European Food Safety Authority have also found no safety concerns with the use of carnauba wax and shellac as food additives. These waxes are applied in very small quantities, with typically only about one drop per apple.

Dr. Alex McDonald, a family medicine physician with Kaiser Permanente Southern California, noted that there is no known dangerous amount of consumed food-grade wax on fruit, as the coating constitutes a minuscule fraction of the apple and is not toxic. He further clarified that any ingested wax is not absorbed by the body and passes through the digestive system.

Both experts highlighted that the efforts to meticulously remove the wax might inadvertently discourage apple consumption. Apples are a valuable source of fiber and nutrients, and ensuring people eat them, wax and all, is important for public health. McDonald stated that the time spent removing wax could be more detrimental if it leads to people eating fewer fruits, as most Americans do not consume enough fruits and fiber in their diet.
