1, which snacks are unhealthy?
1. Boiled corn.
Some corn vendors will add sweet corn essence when cooking corn, which makes the aroma of corn more obvious. Sweet corn flavor mainly contains edible spices and auxiliary materials of edible flavor, which can emit aromatic odor at room temperature, and it is harmless in itself, but once it is used in excess, it will bring harm to the digestive system of human body. Long-term consumption of food containing corn essence will damage the liver, make the detoxification function of the liver decline, affect the normal secretion of digestive enzymes in the stomach and intestines, reduce the absorption capacity of the small intestine, and produce anorexia. In addition, in order to prevent the corn from spoiling when cooked too much, some vendors will also add preservatives to it.
2. stinky tofu.
According to the confession of street vendors, to make black stinky tofu, tofu should be soaked in stinky brine, which is fermented by mixing rotten meat, dead snails recovered from the market, rotten eggs, pickles and swill. If the brine is not black and smelly enough, alkali sulfide and ferrous sulfate should be mixed with water in proportion. After chemical reaction, the water will become darker and smelly. After the brine is boiled, the tofu is soaked in it for half an hour until it stinks, and then the soaked stinky tofu is fried in an oil pan. After frying, it is taken out and dried in a ventilated place. This is how the black stinky tofu is made. When sold in the booth, with the seasoning heated, such stinky tofu smells and tastes delicious far away.
3. sugar-coated haws.
The syrup stays on the hawthorn for a short time, which is very easy to melt, while the Sugar-Coated Berry bought at the vendor can last for a long time. Why? In the regular sales point in Sugar-Coated Berry, syrup is made of high maltose and granulated sugar, but the cost is higher. The red syrup in the black-hearted vendor's pot is an industrial coating mixed with gelatin and saccharin, which is not only low in cost, but also makes the solidified syrup not easy to melt, which is extremely harmful to the health.
4. Baked sweet potatoes.
Coal baking produces toxins. Street baked sweet potatoes are baked with burning coal. The baking process is not only polluted by toxic substances in burning coal, but also polluted by many factors because there is no dust-proof and sanitary facilities on the oven. When coal is burned, it will produce a lot of sulfur dioxide and carbon dioxide, as well as a variety of harmful substances, some of which also contain toxic and harmful substances such as radioactive substances and arsenic. People eating these baked sweet potatoes will lead to chronic arsenic poisoning, and in severe cases, it will damage the digestive and respiratory systems.
5. Mala Tang.
Repeated use of boiled vegetable water may accumulate harmful substances. For example, the content of nitrite and oxalic acid is rising. The media has also repeatedly exposed that the mala Tang stall was mixed with PPA painkillers to prevent customers from diarrhea because of poor hygiene.
