Development of fish collagen peptides in an integrated system to obtain high-value fractions for human nutrition, aquaculture and cosmetics

The FISHCOLBOOSTER project's main objective is to valorize fish by-products rich in collagen-rich protein (mainly tintureira spines and skin) through the development of an integrated process to obtain high-value collagen hydrolysates. The project hopes to obtain a process of separation of spines and mixture with fur, followed by the production of collagen hydrolysates, combining a pre-hydrolysis with temperature and pressing with enzymatic hydrolysis by bromelain, obtained by a sustainable method. The process will result in additional fractions with value, such as hydroxyapatite and functional lipids, which complete the integral valorization of two by-products. Peptide hydrolysates of reduced molecular weight are expected to be obtained, with evidence of various biological activities (with emphasis on antioxidant capacity and promotion of cell regeneration) and good bioavailability, which is at the intestinal level, which is the skin. Formulations of these collagen peptides will be tested in diets for sea bass, in order to assess their potential to increase the robustness of the fish and its resistance to diseases that cause high mortality in aquacultures. Also, as a proof of the value concept of two new ingredients, formulations and prototypes will be developed, combining calcium phosphate and collagen peptides, for the food area, and combining collagen peptides with functional lipids in cosmetics.
