The color of beautiful oranges fades and stains fruit or causes heavy metal poisoning

In autumn and winter, a large number of beautifully colored oranges are on the market. Most of them have bright skin and attractive colors, but they are all “appealing”. The peddler said that just as girls apply lipstick and powder, fruits have to be dressed.

When the skin was peeled, he found a large orange in the orange tissue paper towel. Originally thought to be a water-soaked orange tissue paper, a red blooming appeared. He reached out and touched his hands and found that his hands were full of red.

"Originally oranges were dyed," the netizen said.

Subsequently, the Henan Business Daily reporter found Zijinshan Road, Agricultural Road, near the medical school in Zhengzhou City, supermarkets, fruit stores, have found a bright skin, nice-looking oranges. This kind of orange, the hand feels very smooth, but does not lose color, but if you use a paper towel to wipe hard will leave a red mark.

Zhang, who sells fruit near the medical school, said that the most obvious characteristic of dyed fruit is good color and light. What's more important is that “colored fruits sell well and attract customers to be seen; when they are coated with wax, they are easier to store. Even if they do not sell at half past, they will not dry out.”

"Like a girl applying lipstick and applying powder, fruits have to be dressed." Master Zhang suggested that when selling fruits, it is best to pick seasonal fruits and peel them when they are eaten. It is only safe to eat.

Argument: Dyed fruit or caused by heavy metal poisoning According to national regulations, fruit is strictly prohibited from coloring. For properly harvested fruit, proper cleaning and waxing can be done, but waxing should use professional fruit wax. At the same time, according to the "Sanitary Standards for the Use of Food Additives," sulphur can be used as a food additive within a certain range, but fruits and vegetables are not within the specified scope of use.

Zhang Shijing, director of the Clinical Nutrition Division of the Fourth People’s Hospital of Zhengzhou City, said that there are many small holes in the fruit skin, and the color is very easy to infiltrate into the flesh. Therefore, before eating, it is best to look at the inner skin of the flesh, if the color of fruit penetrates Do not eat it.

Director Zhang said that because it is unclear whether the colors used by hawkers are food grade dyes or industrial dyes, the amount of use is so it is difficult to determine the harm to the human body. However, if it is an industrial dye, it is likely to cause heavy metal poisoning.
