Danger in waxy fruit! Does morpholine cause cancer? Do waxy fruits pose a health risk?

Pay attention to the fruits that attract with their eye-catching shine on the grocery counter! This trick on fruits to extend their shelf life and make them appear attractive to the consumer can be fatal. The candle, which provides the beauty of the bright fruits we buy from the market, poses a health risk. Especially the apples and red plums that we consume with their skins because they are healthy threaten our health with a danger we do not know. And most people are not aware of this danger.

Head of Gastronomy Department Dr. Faculty Member İlkay Gök gave information about the morpholine and cancer risk in waxy fruits.

İlkay Gök, “I compare the problem we have while biting the shining red apples to the story of a cotton princess who bites the red apple and falls asleep. She falls asleep, and we face a slightly greater risk: Cancer!” says. Head of Gastronomy Department Dr. İlkay Gök, Faculty Member, explained the great danger in fruits.


In general, we do not only wash fruits and vegetables under water, but we can apply different processes. For example, we soak in vinegar water. It can be beneficial to soak in water for germs and pesticides, but it is definitely not enough to clean the wax on it.

In other words, we safely eat the fruits we eat with their wax because they have been washed thoroughly, kept in vinegar and cleaned very well. Under normal conditions at home, it is almost impossible to clean the wax on the shell.

It is a liquid waxy solution that the fruits are dipped or sprayed on before coming to the counter to make them look shiny, not lose moisture, and protect them from insects.

It is not easy to see the candle on the fruit. The wax on it cannot be removed by hand rubbing, soaking in warm water or vinegar for a few days. After rubbing it thoroughly and soaking in vinegar water for a few days, the wax layer was still standing on the apple that I scraped with a knife.


There is another hidden danger that is actually invisible when we dwell on pesticide hormone-related issues in fruits. The chemicals used in the wax solution threaten our health if they are not used at the right rate.

So eating with crust can be risky. While waxing improves the product visually, it is also used because it slows down physiological events by reducing water loss. Decays are decreasing. Turkey’s allowed to use the 6 varieties.


Fruits: Citrus fruits (lemon, mandarin, orange, grapefruit), apple, pear, peach, pineapple, pomegranate, mango, avocado, papaya.

Vegetables: Melon, watermelon, cucumber, eggplant, pepper, pumpkin, sweet potato, tomato, potato.

To apply the waxes used in liquid form, it is common to use emulsified waxes, as heating the waxes can damage the product. For this reason, emulsifying agents are added to waxes. The most important of these substances is morpholine (C4H9NO).

The substances in the wax solutions used have lower and upper limits. The most dangerous of these is the substance called Morpholine. Morpholine is present in almost all mixtures used.


Stating that candles containing morpholine or other amines are banned in Europe, Dr. İlkay Gök, Faculty Member, said:

“Morpholine can react with nitrate in the diet to form N-nitrosomorpholine (NMOR). N-nitrosomorpholine (NMOR) is a carcinogenic substance. Morpholine at 0.03-0.3ppm levels is stated to be low risk for human health. Above this level, morpholine is toxic and unsafe, The use of waxes containing morpholine or other amines as a coating has been prohibited by the European Union. What about us? Are they controlled? Is there morpholine in the content of the wax used in the food I consume, is the amount within legal limits? I don’t want to eat the shining apple, but the apple that has been picked from its branch, with the peel. Is it necessary to use candles for a country like us that produces many apples / fruits? “
