Simply by pouring hot water over an apple, you can check whether it's safe or contains preservatives that are dangerous to your health.

Why does pouring hot water on an apple help detect if it's poisoned?

Most apples are covered in a waxy coating. To check if an apple contains dangerous preservatives, try pouring some freshly boiled water over it. Wait a moment, and you will see a waxy layer appear. These are the apples that are harmful to your health.

How does the wax coating on apples affect human health?

Everyone knows that apples are one of the fruits rich in vitamins, and nutrition experts recommend eating them daily.

But worryingly, the apples currently being sold in the market are all being warned as being coated with wax and preservatives.

Apples themselves already have a natural protective layer of wax. But to increase the fruit's "shelf life," people can spray them with a protective wax coating.

Many companies have produced waxes made from natural ingredients such as beeswax, carnauba wax, red willow resin, fatty acids, etc., which are safe for health. However, the cost of these preservatives is very high.

Therefore, many small traders and gardeners have used a type of wax coating containing fungicides, bactericides, preservatives, and artificial dyes to make the fruit look beautiful and allow it to be stored for a long time.

Moreover, industrial dyes themselves can damage memory, the immune system, and cause respiratory problems in humans if exposed.

The claim that body wax can cause cancer in those who use it is still a subject of much debate.

How to remove the wax layer from an apple.

With the apples we buy at the market, there's no guarantee they're preserved with a natural wax coating, especially when their price is "average." Therefore, to ensure the safety of your family, in addition to buying apples from reputable sources, you should follow these steps to remove harmful substances before eating:

Step 1: Place the purchased apples in a small bowl and add one spoonful of baking soda, one tablespoon of lemon juice, and a little warm water.

Step 2: Roll the apples evenly in the mixture. Then, using a very soft toothbrush, gently and carefully scrub the outside of the apple peel to remove all the protective wax coating.

Remember to peel the apple before eating, even if the waxy layer has already been removed.

How to use and store apples safely and ensure quality.

– You should choose to buy apples from reputable import stores, branded stores, or large supermarkets. Avoid buying from street vendors or stalls whose origin and source of apples are unknown.

– When buying apples, if you plan to eat them immediately, wash them thoroughly before peeling. After peeling, to prevent the apples from browning, soak them in warm water mixed with a little lemon juice. This will help the apples retain their color longer and stay fresh for many hours.

– If you want to preserve apples for a long time and use them over several days, wrap them in a perforated plastic bag, tie it tightly, and put it in the refrigerator's crisper drawer.

Note: Chinese apples are usually round, with a smooth, shiny, and attractive skin, and are carefully wrapped in foam. If you look closely, you will see many fine white particles on the skin when you peel off the foam. Sometimes these are thin, translucent white films, or distinct ones; these are due to the evaporation and condensation of preservatives.
