In the season when the oranges went public, the oranges were sweet, sour, and nutritious. However, some people find that after eating oranges, they turn red, which means that oranges are stained. What is the danger of this kind of bright orange dyeing, and how do you distinguish dyed oranges?

    To "stain" the orange to make it even brighter

    The coloring of oranges by businesses is a factor of economic interest. Some oranges are not mature enough, and their appearance is not good. However, in order to grab the morning market and sell a good price, the growers took off the oranges and processed them with pigments. Some businesses use pigments to treat the orange skin in order to make the orange look brighter and increase the unit price.

    Some poor-quality oranges have undergone "processing" and their prices have increased a lot. It is precisely this economic interest that drives consumers to bear the health hazards of dyeing oranges.

    Stained oranges harm to the body

    Because the fruit skin has a lot of holes that are invisible to the naked eye, the dye can easily seep into the interior. Moreover, it is not clear whether the hawkers use food-grade dyes or industrial dyes, and the amount of use, so it is difficult to determine how harmful the human body is. If industrial dyes are used, heavy metals are likely to exceed the standard, which may lead to chronic poisoning and affect internal organ function. For example, agricultural products containing cadmium can cause kidney, lung, and bone lesions in humans.
 

    Even if the merchant claims that dyeing cannot penetrate into the flesh, is it really safer?

    Although the skin of the orange is thick, the dye cannot penetrate into the skin. However, when the skin is peeled or cut, some of the dye is contaminated with the pulp. Therefore, if the orange is found, it is best not to eat it.

    How to distinguish dyed oranges

    one look. Colored oranges look particularly red on the surface, and there are red spots in the pores of the epidermis. Dyed oranges, orange pedicles turn red; unstained oranges, orange pedicles are white and green.

    Second, smell. Dyed oranges are often stimulating with chemicals, and unstained oranges have a hint of light fragrance.

    Third, wipe. Wipe the surface of the orange with wipes. If the wipes turn red, the oranges may be stained. For unstained oranges, the wipes only look faint yellow after wiping.

    Be sure to pay more attention when you buy oranges. Don't be fooled by the oranges that look so beautiful.
