Re: Ji'nan street snacks are mostly black list: spicy hot soup plus antidiarrheal for many days.
the reporter bought 4 spicy hot soup bases from different locations in Ji'nan to the food inspection agency.
the staff took 5ml solution from each soup bottom, then added the decolorant to make the soup bottom color clear and put it into centrifuge. Centrifuges can separate solids from liquids in soup bottom and reduce data errors. After the above operation, the staff took the cleaning fluid into the test tube and dropped the nitrite detection reagent and shook it. In 10 minutes, compared with the standard color plate, the sample showed the purple red, which contained the nitrite, the deeper the color was, the higher the content was. The experimental results showed that 4 soup bottom contained nitrite, 1.0mg/L, 0.25mg/L, 5mg/L and 0.25mg/L respectively.
a professor of chemistry at University of Jinan told reporters that nitrite is a precursor substance of nitrosamines. In nature, nitrite is easily combined with amines to form nitrosamines. In the acid environment of the stomach, nitrite can be converted to nitrosamines, and nitrosamines are strong carcinogens. If we eat food with high nitrite content for a long time, or directly eat foods containing nitrosamines, it can induce cancer.
in addition, most of the hot hot soup with high fat material as the bottom material, and more with chili, pepper and pepper as seasoning, eat more easily lead to hyperlipidemia, duodenal ulcer, oral ulcer, gingivitis, hemorrhoids and other diseases. At the same time, ordinary plastic bags or plastic bowls used by people in eating spicy hot peppery are mostly made from PVC (PVC). These non food packaging products will release toxic substances in high temperature and cause harm to the human body.
industry, a pot of soup plus antidiarrheal, in a lot of days
in the seven Li Mountain convenience market, a spicy hot stall on a series of already good balls, vegetables, thick layer of oil stains hanging in the stainless steel pot, jute sauce in a tin pot, the paper box under the stall with the used bamboo sticks. These bamboo sticks will be recycled until the bamboo sticks are broken.
"the spicy string that we cook is never eaten by ourselves, because it is too dirty." Ms. Wang, who once sold spicy spicy string, told reporters that in order to reduce the cost, a pot of soup will be used for many days. In order to prevent the customers from having diarrhea after eating the meatballs, many peddlers added antidiarrheal drugs in the soup. Wang Weiqing, the two grade nutritionist of the state, said that, without mentioning the harmful ingredients of soup, only repeated boiling soup could produce carcinogens. The contents of
4, 1 gluten, more than
roadside stalls, are also popular for selling baked gluten stalls. However, some netizens reported to the newspaper that in order to bleach, the baking gluten added carcinogenic baits. Reporters bought 4 samples on the streets of Ji'nan and sent them to Beijing Sai Da Da Technology Co., Ltd., and found that 1 pieces of gluten were over standard.
experimental results 4 gluten, 1 white blocks exceeding the standard
the staff used electronic balance to take 2G samples in the sample cup, add 18mL distilled water or pure water for 10 minutes, get the sample solution; take the 2mL sample solution to the color dish, add the 4 drops of A, shake well, and then add 1 drops of detection solution B, After mixing, immediately put into the white block detection channel to adjust zero; remove the zero after removing, statically set for 5 minutes; then add 1 drops of detection liquid C, mix well; finally, after the rest 3 minutes, concussion is mixed, put in the detection channel for the detection of the white block. The results showed that 4 gluten in the reporter bought a gluten test concentration.
