On the afternoon of that afternoon, Yu Hai, a market regulator of Ruian, was involved in the investigation. The aquatic product stall seller had already returned Ms. Zheng's 100 yuan purchase of shrimp. events: shrimps drop some of the gelatinous substance
7 month 13. Ms. Zheng, who lives in Tao Shan, Ruian, bought three prawns in the South Gate farmer market of the city. The three shrimps weighed 782. She said the shrimp had only been eaten in the hotel before, and it was the first time to see the market. So she bought some of them to take home and let my mother make a good dish, and the three shrimp, Ms. Zheng, paid 100 yuan.
however, when Zheng returned home, Zheng's mother found the problem in cleaning the shrimp. The
shrimp line has been disposed of by the peddlers. However, when the shrimp shells were removed, some gelatinous substances were dropped from the shrimp heads and the body. She had also seen some shrimps injected with gelatin on the Internet, so she was particularly attentive when dealing with shrimp. She immediately told Ms. Zheng that the shrimp had a problem: "you were cheated, and the shrimp was injected with gelatin."
because she did not know whether the unknown substances were toxic, Ms Cheng did not dare to eat it hastily.
survey: the stall vendor called the shrimp the wholesale
after that, Ms. Zheng released pictures of some shrimps through micro-blog, denouncing the "profiteers", and quickly attracted the attention of netizens and local regulators.
the afternoon of the day of the incident, the law enforcement officers and Ms. Zheng of the Ruian Market Supervision Bureau came to the South Gate farmer's market. The stall was not in business, so the law enforcement officers called Zhang Mou to the scene to understand the situation.
Zhang looked at the gelatinous substance in the prawn, and said he did not know what it was.
Zhang introduced that these prawns were wholesale from Cangnan, and he had been selling them since last year. He bought 10 jin of prawns on the same day, and the price was 180 yuan per kilogram, which is now sold out. Subsequently, Zhang returned to Zheng 100 yuan to buy shrimp, and the law enforcement officers took it away for investigation.
industry: gelatin can increase weight and sell better.
law enforcement officers indicate what the glue is and need further investigation. The South Gate farmers' market has gathered a large number of aquatic vendors. According to an aquaculture owner, some frozen prawns, because the shrimps will appear dry after thawing, and the weight will be reduced. So some people will be injected with gelatin on the shrimp head and prawns to increase the weight and sell the frozen shrimps, so the "shrimps" are in many places. .
the reporter learned that the glue in the "glue shrimp" looked transparent, dispersed with a pinch hand, and was easily burned after drying, and the pinch was powdery after carbonization.
Dr. Li Zhongyu of the school of chemical and material engineering of Wenzhou University speculates that this colloid may be a gelatin material, but it is not yet determined by the naked eye. "What is the specific substance that needs to be determined by professional bodies".
