Apples are coated with shellac and carnauba wax to improve their shine
because consumers prefer to buy shiny apples. It gives the fruit or
vegetable a sheen, which in the eyes of some customers is a sign of
quality. Wax is used for a preservation purpose and then cold stored. A
coating of wax helps seal in moisture and therefore extends storage
life, as well as minimizing costly weight loss. You might be surprised
especially the imported apples are more than one year old, though it
would look fresh.
Food industry spokespersons claim that the wax is safe to eat, it does give food an off-flavor. It also hampers your efforts to scrub off pesticides that may have been sprayed on the fruit before it was waxed
. These coatings are not harmful, but you should always rinse your apples with soap and water or with vinegar
before you eat them. A home sanitization system, such as a Lotus Home Sanitization
System is another option to remove the pesticides and bacteria on produce and other food stuffs.
