Biodegradable films from fish skin

The researcher of Cretus from the University of Santiago de Compostela (USC), Cristina Gallego Rodríguez, has carried out a thesis in which the MANUFACTURE OF BIODEGRAPABLE FILMS FROM TUNA SKIN.

As the USC has transferred in a press release, the main objective of the thesis was “Optimize the gelatin extraction process from the Skin of this fish for maximize the performance and properties of the final product“

For that, they were used “safe and sustainable” eutctic solvents “ with exploration of variables such as time, temperature and solvent proportion to define the optimal conditions of the process.

In this context, the results demonstrated the possibility of obtaining gelatin suitable for the elaboration of biodegradable films, with a “important potential” application in sectors such as the food industry.

Thus, the thesis “expands the alternatives for the Sustainable use of marine resources“And reveals” viability of an accessible and adaptable technology to different production scales“
