The invention relates to a collagen product containing collagen of marine origin with a low odor. The collagen product includes one or more collagens or derivatives thereof, including hydrolyzates, with a low odor, at least part of the collagen or the derivatives being of marine origin and having been subjected to a deodorization treatment, particularly with an oxidizing substance such as a sulfite, hydrogen peroxide or ozone, at any stage of the manufacture of the collagen product. The invention also makes it possible to improve the mechanical properties and to use this low-odor collagen product in cosmetic or pharmaceutical products.

A new composition is disclosed which serves as a substitute for the bony matrix material present in bones. The new composition includes an association of collagen-hydroxy-apatite and a glycosaminoglycan. The concentration of the hydroxyapatite is preferably 15 to 25% and the concentration of the glycosaminoglycan is between 1 and 2% per liter of 1% collagen gel. The biomaterial product is useful in applications in reconstructive orthopedic surgery as a substitute for natural bone matrix material.
