Checking fish for freshness can now take seconds instead of hours or days. Scientists from Cherepovets State University, together with colleagues from Abdul Malik Al Saadi University in Tetouan, have developed a system that determines the quality of fish products on the conveyor and shows whether they can be sent to production.
The development was announced by the Governor of the Vologda Oblast, Georgy Filimonov. According to him, the "smart camera" is able to check the quality of fish in a few seconds with an accuracy of up to 90%. The system works without contact, directly during the movement of the fillet on the conveyor.
The data is analyzed using a neural network. The system determines fat oxidation, bacterial activity, and biochemical changes. After that, a final conclusion is issued: whether to put the fish into production or dispose of it.
Currently, fish is checked at enterprises using a random sampling method. This process takes from several hours to several days. Sometimes this leads to the suspension of the sale of an entire batch of products.
The development of Cherepovets scientists, as Filimonov noted, radically changes the very approach to quality control.
The introduction of the system will help reduce the share of low-quality raw materials on the market, reducing the costs of processors and the risks for retail chains.
In the future, the development is planned to be made more universal.
