Fish Residues Could Supply Collagen

Researchers in Norway believe fish residues can supplement current sources of raw materials for collagen and gelatin, according to a Phys.org article.

A project called SUPREME, headed by the Norwegian science institute SINTEF Ocean in collaboration with Norwegian university NTNU and the Technical University of Denmark, among others, involves developing technologies that can boost utilization of fish residues to optimize exploitation of biomarine resources. One aspect being studied is whether fish skin can be used to manufacture collagen and gelatin.

“Fish-derived collagen is often of higher quality and enables people who don’t eat meat to enjoy products containing gelatin,” Rosa Slizyte, a senior research scientist for SINTEF Ocean, tells Phys.org. “If we optimize our exploitation of whitefish residues, we can produce more than 6,500 tons of gelatin from fish skin every year.”
