Pictures and news of using gelatin to put weight on crabs have spread quickly online, raising concerns among consumers about eating crabs. Is there such a gelatinized crab on the market? Is it safe to eat? In order to answer the concerns of consumers, recently, the market Supervision Bureau of Jiaojiang District, Taizhou City, Zhejiang Province, and the Consumer Protection Commission specially organized a on-site consumer experience.

On February 7, the Jiaojiang Market Supervision Bureau and the Jiaojiang Consumer Protection Committee organized personnel to carry out the experiment of giving crabs gelatin needles in the free rapid testing room of the local Wanji Pond dish market, witnessed by media reporters, representatives of the masses and live broadcast netizens. In order to reflect fairness, the crabs were bought by local consumer rights protection volunteers in Jiaojiang, who randomly purchased 3 male crabs and 3 female crabs. At the same time, in order to be fair, the on-site experiment is Taizhou Yucai Primary School biology teacher - Teacher Lin. Or for the sake of fairness, the on-site data recording is Taizhou Yucai Primary school volunteer students.

Three male and three female crabs were given "tasks." One for comparison, one for 3ml of water, one for 3ml of gelatin. Under the operation of Teacher Lin, the results of the scene came out soon. Three male crabs -- after 10 minutes, the glued one was barely alive and could fit his fingers in the pincers. The two without glue put the ballpoint pen into the pliers, and soon the ballpoint pen was broken by the pliers. Three female crabs -- the glue one -- also died in less than 10 minutes.

Can you gain weight by gluing? The volunteer primary school students were weighed on site, and the data showed that the weight gain of water injection was not large, indicating that the glue could indeed play a certain role in weight gain. Market operators told reporters that even if gelatin can gain weight, no operators are willing to do so. The reason is simple, because the crab will die very quickly after gluing.

The operator calculated an account to the reporter: he sold crabs, 100 yuan/kg, each crab is 100 grams; If he puts glue on the crabs, he can inject 3 grams each time and earn an extra 3 cents each; But the crab to make a hole, half an hour is bound to die, live crab price is 100 yuan/kg, dead crab price is 10 yuan per kg, operators will not do this loss of business.

The person in charge of the Jiaojiang Market Supervision Bureau and the Consumer Protection Commission said that after investigation, the crab glue photos and news published online were actually spread in 2014, and later verified by relevant institutions and individuals, and the rumors were refuted at that time. I didn't expect that a few years later, someone took out the hype. Conducting a field experiment like this is simple: buy a crab, give it a shot, and in 10 minutes you can verify a rumor. Consumers who are in doubt can also experiment on their own at home. At the same time, the Jiaojiang Market Supervision Bureau and the person in charge of the Consumer Protection Commission hope that everyone can turn over more rumors, so that more people can rest assured to eat crab.
