Food producers put food-grade wax on apples to extend their shelf life and make them look shiny and appealing on supermarket shelves. This wax is typically a type of emulsion made with carnauba wax.
Why Wax is Applied to Apples
The natural wax coating on apples can be lost during the washing and handling process. This can lead to faster spoilage, moisture loss, and a less attractive appearance. To combat this, a layer of food-grade wax is applied.
Types of Wax Used
- Carnauba wax: A natural wax derived from the leaves of the carnauba palm, commonly used for its gloss and protective properties.
- Other waxes: Food-grade waxes may include beeswax, shellac, and petroleum-based waxes, although carnauba wax is the most prevalent.
Benefits of Applying Wax
- Extends shelf life: The wax coating helps to seal in moisture, reducing dehydration and preventing premature spoilage.
- Enhances appearance: The wax provides a shiny, glossy finish that makes the apples more attractive to consumers.
- Protection: The wax coating provides a barrier against bruising and minor abrasions during handling and shipping.
How Wax is Applied
The wax is usually applied after washing and sorting, using specialized equipment that evenly coats the apples.
Safety Considerations
The food-grade waxes used are considered safe for human consumption and are regulated by health authorities.
Is it Safe to Consume Apples with Wax Coating?
Yes, the food-grade waxes applied to apples are safe for consumption, as they are regulated and approved by health authorities. However, if you prefer, you can wash apples thoroughly before consumption or peel the apples.
