Why coat apple fruits



Why coat apple fruits:
----------------------------

There are several reasons for coating apples. The main reasons are either for preservation, aesthetic (appearance) or the obvious one of replacing the natural wax.

The apples, naturally have a natural wax coating on their surface. This natural wax coating helps to protect the apple fruit from shriveling and weight loss. However, prior to packaging of the apple fruits, they are washed by scrubbing the surface to remove dirt and chemical residues (if they are not organic). This scrubbing removes approximately 50% of the natural wax coating.

To replace the natural wax coating, processors apply other recommended waxes on the surface of apples. The waxes applied on apples can either be animal wax, vegetable wax or mineral and synthetic wax. After applying wax, the fruits assumes glossy and firm appearance which is considered as an important quality in apples.

The distributors and sellers of apples can apply wax to improve appearance and increase visual freshness. This is very common practice especially in supermarkets.

The most common wax used on apples is a vegetable wax called canauba wax or shellac.


Ways of cleaning waxed apples
---------------------------------------
Obviously, it is a good practice to clean apples before eating. I would suggest cleaning with lukewarm water. Just clean them thoroughly to remove any surface wax. This would also help remove any dirt and chemical residues on the surface.

It is not advisable to use detergents even food grade types on porous fruits like apples.

Vinegar (acetic acid) can also do. Use a paper towel with a bit of vinegar to wipe the fruit before washing. Using vinegar wipes away the wax.

The other obvious way to ensure you do not consume the wax on the surface of apples is to remove the entire peel . This can be done by using either a fruit peeler or a knife. This comes at a cost since many people like the tartness and crispiness of the peel.
