Freshly harvested, the apples still have a matt, slightly rough skin. However, after some time of storage or when you buy the fruit in the supermarket, the skin appears shiny and greasy. That's why many consumers ask themselves the question: Were the apples artificially waxed?
Why do apples sometimes have shiny skin?
The natural wax layer of apples is created primarily during storage to keep them fresh and protect them from predators. A shiny apple from regional cultivation in Germany means a natural protective layer, as artificial growth is prohibited here.
Where does the shine come from?
This layer is natural wax, which forms the fruit to protect it from predators. The longer the apple is stored, the more intense the wax layer becomes and the more shiny the skin becomes. The support on the peel ensures that the fruit does not dry out and remains crisp and fresh.
How thick this wax layer is depends on the apple variety:
- Sweet varieties like Jonagold form a very thick layer that makes the apple look like it has been polished with grease.
- Apple varieties that are sour, such as Boskop or Cox Orange, only have a thin layer of wax. Even after months of storage, their shell feels rough and hardly shines.
An artificial wax layer as protection
For apple varieties that spoil quickly, fruit growers can apply an artificial wax layer that keeps the apple fresh and protects it from insect attack.
In Germany, however, this measure is not permitted, unlike other countries. So when you buy a shiny, locally grown apple, you can be sure that it is the natural protective layer.
If apples are artificially waxed, this must be clearly declared on the packaging. The cushion usually consists of one of the following materials:
- Beeswax
- Candelilla wax,
- Carnauba wax,
- Shellac.
This protective layer is harmless to he alth and can be consumed. However, it is advisable to wash waxed apples thoroughly with warm water. Since there are valuable nutrients under the peel, you should only peel the fruit if you are sensitive to the substances applied.
Tip
When buying, make sure that the apples are plump and smooth and that there are no bruises on the skin. These characteristics indicate freshness and correct storage until sale.
