From waste to health: Valorization of Atlantic salmon (Salmo salar) by-products as a source of marine collagen

The global market of marine collagen-added products is tremendously growing, leading to the need for a stable and enormous supply of marine collagen. Atlantic salmon scales and skin are abundant in collagen, however no research has been performed for its extraction. The proposed project will develop an efficient extraction process to maximize the collagen yield, and purify the extracted collagen for its use as the functional ingredient in nutritional supplements and cosmetic products. This research will create a large and lasting supply of marine collagen to the market, so companies that produce and sell marine collagen-added products can have stable and low-cost production of high-value products with competitive price. Furthermore, this project will promote valorization of the large amounts of Atlantic salmon by-products for value addition.
