Food safety: What is squid hair tonic?

Hair spray is dried seafood, which is soaked in water and then restored to its original appearance. For example, sea cucumber, scallop, squid, shrimp and so on are all dried products. The squid hair spray is specially used to treat squid.

Squid hair spray contains alkali, which is corrosive and difficult to contact directly. Excessive soaking squid will produce toxic ingredients, which is harmful to people.

It is understood that adding caustic soda to aquatic products such as squid, shrimp, tendon, sea cucumber, hairy belly, duck intestines and fresh shrimp can increase the weight by 5 to 7 times, and the body moisture is not easy to go out.

the shelf life of the product can be extended by 3 to 5 times, and the product looks plump and shiny. Therefore, some vendors who have no frozen storage conditions and want to make ill-gotten gains naturally soak aquatic products with caustic soda, which not only sells well, but also is not easily perceived by consumers.

Comrades from the industry and commerce and quality supervision departments said that at present, there is no simple method suitable for ordinary people to detect whether there is formaldehyde in aquatic seafood products, and the manpower and material resources are very limited by qualitative inspection by professional departments.

in practical work, only when the departments of health and epidemic prevention, quality supervision and industrial and commercial administration join hands, check all aspects of operation, strengthen testing and inspection, build a monitoring network, and enhance people's awareness of self-protection, can the market of aquatic products be effectively controlled.

Example:

In the aquatic products market, the aquatic products sold in some stalls look particularly beautiful, especially the aquatic squid is fat, and the beef venetian is fat and white, giving people a crisp feeling when touched by hand. While soliciting customers, the bosses stressed: "I made it myself with caustic soda, and there is absolutely no formaldehyde."

the staff of the market management office said that under normal circumstances, water-based products would not be so big after being soaked in edible alkali. Sure enough, in front of a merchant's door, two pots of beef venetian blinds formed a sharp contrast, one pot was black and small, and the other pot was white and big. Upon inquiry, the stall owner admitted that the small black pot had not yet had time to "process", while the other pot had been soaked in caustic soda.

the stall owner said that the aquatic products on the market are all soaked in caustic soda, and if they are not soaked, they will not be sold at all. Regarding the safety of water products soaked in caustic soda, the technicians of the Institute of Product Quality Metrology and Testing of Xing 'an League Bureau of Quality and Technical Supervision told the reporter that caustic soda is a strong alkali, and if it is added to food, it will lead to excessive formaldehyde content, which is harmful to the human body.

The use of caustic soda and hydrogen peroxide to soak aquatic products has long been prohibited in China. Vendors use caustic soda to process water products, and there is no strict standard on the dosage, which often leads to large dosage and great harm.

the shelf life of the product can be extended by 3 to 5 times, and the product looks plump and shiny. Therefore, some vendors who have no frozen storage conditions and want to make ill-gotten gains naturally soak aquatic products with caustic soda, which not only sells well, but also is not easily perceived by consumers.

In order to ensure good health, the Consumers Association suggests to consumers: first, carefully check the manufacturer's name, certificate of conformity, health inspection certificate and treatment technology of the products; Secondly, ask and ask the distributor to fill in the purchase invoice correctly and keep the necessary evidence such as product packaging properly to prevent the distributor from refusing to admit it after being deceived and causing personal injury.
