It has been a few years since seeing yellow and orange oranges and tangerines in the fruit basket in late summer and early fall has become a normal thing. Fruits, which, of course, are bitter and sour, contrary to their color and appearance. But the question is, why do these citrus fruits enter the market with this color and glaze before the harvest season, and where does this yellow color come from?
Colored fruits
"Colored" is the term used for the colorful but dull citrus fruits of these days' fruit markets. Fruits that enter the market without any supervision and are sold with high quality. Most of the people are happy with the warm and yellow color of the fruits, they think they buy an autumn fresh fruit and take it home, but after peeling the fruit, they realize that it is whole. As if this yellow and orange color is not the natural color of orange.
A point that the head of the Iranian gardeners' union has implicitly confirmed. "Mujtabi Shadlou" said: "In the last few years, some profiteers buy oranges from gardeners before the harvest season and use machines to color the oranges and change the orange color from green to yellow or half yellow and green." "
According to the head of gardeners' union, such fruits are harmful to health. Because the orange fruit itself has acid, and due to heating, its acid level increases, and in addition to losing its properties, it is very dangerous for the digestive system. But the coloring of fruits or degreening is done in two ways, and the method of coloring with "ethylene gas" is more used in our country.
They bite so that you bite
Picked fruit baskets can be brought to consumption conditions in a controlled environment. This is what has caused some people to abuse it to sell artificial fruits and berries. They expose the picked fruits to ethylene gas. Ethylene destroys the green chlorophyll pigments and releases the yellow pigment enclosed under the chlorophyll. In this way, the green fruit looks like a ripe fruit, so that its attractive color and face can find more customers in the fresh fruit market. The use of ethylene is mostly used in fruit baskets such as bananas, persimmons and tomatoes.
From sparrow coloring to fruit coloring
Perhaps the most suitable analogy for this method is the proverb "They paint a sparrow and sell a canary." Kal fruits are colored in two ways.
In the first method, they first turn the color of the fruits with ethylene gas and then immerse them in a colored solution so that the color of the fruits becomes brighter and more shiny.
The second method is slightly different. In this method, there is no ethylene gas, and citrus fruits are immersed in dye solutions with a higher concentration from the very beginning. The fruits are immersed in water at 50°C for 20 minutes until the color is absorbed by the skin of the fruit and uniform. After that, the fruits are cooled and waxed. Of course, this method is rarely done in our country. But its traces can be seen in imported fruit baskets. In this method, chemicals may penetrate into the fruit and cause poisoning and even cancer.
Autumn fruits and especially citrus fruits due to the presence of vitamin C in the food basket
Autumn fruits and especially citrus fruits are in the autumn and winter food basket of families due to their vitamin C content. Fruits, of course, are useful for the prevention and treatment of diseases such as colds. However, coloring and the rush of profiteers to conquer the fruit market and sell more have caused one of the healthiest foods in the family's fruit basket to be contaminated with chemicals.
Unripe citrus fruits do not have much nutritional value. What if they enter the market after passing these steps. Autumn fruits, especially citrus fruits, are in the family's autumn and winter fruit basket due to their vitamin C content. Fruits, of course, are useful for the prevention and treatment of diseases such as colds. But the coloring and rush of profiteers to conquer the fruit market and sell more has caused one of the healthiest foods in the family's fruit basket to be contaminated with chemicals.
Perhaps the best thing to do to stay away from dyed fruits is to not rush and wait for its natural and usual season to consume any fruit. With this method, no one can color you with colored fruits.
Sticky or shiny fruits are poisonous
The head of the Department of Agricultural Health of the Ministry of Health, Treatment and Medical Education warned that although the residual toxins on the fruits do not have any special symptoms, sticky or shiny is a sign of residual toxins on them.
Reza Ezzatian added: Also, some fruits impregnated with toxic residues have the smell and taste of chemicals like oil.
He pointed out that if a fruit has an unnatural taste and smell, chemicals have definitely been used for its growth and processing.
The head of the Department of Agricultural Health of the Ministry of Health asked people to be careful about the remaining toxins in fruits and vegetables.
Ezzatian also said about monitoring the use of pesticides in fruits: the relevant agencies monitor the implementation of laws in this field, but if people and producers become familiar with the description of their duties, they will help prevent poisoning caused by residual toxins on fruits.
He pointed out that the most important action of the Ministry of Health in this field is to maintain the relationship with the Jihad of Agriculture, and we review the legal tasks and duties related to the use of pesticides in fruits by holding meetings of the Agricultural Health and the National Committee of Agriculture.
According to the head of the Department of Agricultural Health of the Ministry of Health, the permissible amount of pesticide use is notified provincially.
Ezzatian mentioned that in order to prevent poisoning caused by the remaining toxins on fruits, consumers and farmers as producers should be culturally ready to accept and comply with the standards.
