How Significant Are Marine Invertebrate Collagens? Exploring Trends in Research and Innovation

Summary

This review is focused on the research, innovation and technological breakthroughs on marine invertebrate collagens and their applications. The findings reveal
that research dates back to the 1970s, and after a period of reduced activity, interest in
collagens from several marine invertebrate groups was renewed around 2008, likely driven
by the increased commercial interest in these biomolecules of marine origin. Research and
development are predominantly reported from China and Japan, highlighting significant
research interest in cnidarians (jellyfish), echinoderms (sea cucumbers, sea urchins and
starfish), molluscs (squid and cuttlefish) and sponges. Co-word analysis of the literature
highlights applications in regenerative medicine, the properties of hydrolysates, and biology and biochemistry studies. Innovation and the technological landscape, however, focus
on fewer taxonomic groups, possibly reflecting the challenge of sustainably sourcing raw
materials, with a higher number of patents coming from Asia. Globally, jellyfish collagen
is the most prominent marine invertebrate source, while Asia also emphasizes the use
of collagens derived from molluscs and sea cucumbers. Europe, despite fewer patents,
explores a broader range of taxonomic groups. Globally, key applications registered are
mostly in medical, dental and toiletry areas, with peptide preparations spanning multiple
animal groups. The food domain is notably relevant for molluscs and sea cucumbers.
Market trends show a strong presence of cosmetic and supplement products, aligning
with market reports that predict a growing demand for marine collagens in cosmetics and
personalized nutrition, particularly in targeted health supplements.
