In the last two decades, marine collagen has attracted great scientific and industrial interest as a ‘blue resource’, with potential for use in various health-related sectors, such as food, medicine, pharmaceutics and cosmetics. In particular, the large availability of polluting by-products from the fish processing industry has been the key factor driving the research towards the conversion of these low cost by-products (e.g. fish skin and scales) into collagen-based products with high added value and low environmental impact. After addressing the extraction of collagen from aquatic sources and its physicochemical properties, this review focuses on the use of marine collagen and its derivatives (e.g. gelatin and peptides) in different healthcare sectors. Particular attention is given to the bioactive properties of marine collagen that are being explored in preclinical and clinical studies, and pave the way to an increased demand for this biomaterial in the next future. In this context, in addition to the use of native collagen for the development of tissue engineering or wound healing devices, particularly relevant is the use of gelatin and peptides for the development of dietary supplements and nutraceuticals, specifically directed to weight management and glycemic control.

Abstract
In the last two decades, marine collagen has attracted great scientific and industrial interest as a ‘blue resource’, with potential for use in various health-related sectors, such as food, medicine, pharmaceutics and cosmetics. In particular, the large availability of polluting by-products from the fish processing industry has been the key factor driving the research towards the conversion of these low cost by-products (e.g. fish skin and scales) into collagen-based products with high added value and low environmental impact. After addressing the extraction of collagen from aquatic sources and its physicochemical properties, this review focuses on the use of marine collagen and its derivatives (e.g. gelatin and peptides) in different healthcare sectors. Particular attention is given to the bioactive properties of marine collagen that are being explored in preclinical and clinical studies, and pave the way to an increased demand for this biomaterial in the next future. In this context, in addition to the use of native collagen for the development of tissue engineering or wound healing devices, particularly relevant is the use of gelatin and peptides for the development of dietary supplements and nutraceuticals, specifically directed to weight management and glycemic control. The marine collagen market is also briefly discussed to highlight the opportunities and the most profitable areas of interest.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
