Synopsis Sufficiently pure collagenous hydrolysates, suitable for application in skin and hair care cosmetics, have been prepared through biotechnological methods with the use of commercially available enzymatic preparations from short cattle tendons (musculus extensor communis, musculus flexor digitorum, musculus flexor digitorum profundis). These hydrolysates contain neither lipoid nor aminosaccharide components, content of primary amino groups reaches around 1.1 mmol g and the average molecular weight of the resulting collagenous hydrolysates does not exceed 2000 g mol (2.0 kDa). Short cattle tendons represent a relatively pure and easily available source of collagens and are, despite their generally known low nutritional value, used only as a feeding mixture component.

Résumé

On a préparé par des méthodes biotechnologiques des hydrolysats de collagène suffisamment purs, adéquats pour des applications en cosmétiques de soin pour la peau et les cheveux, en utilisant des préparations enzymatiques, disponibles dans le commerce, à partir de tendons courts de bétail (musculus extensor communis, musculus flexor digitorum, musculus flexor digitorum profundis). Ces hydrolysats ne contiennent pas de composants lipoïdes ni d'aminosaccharides, la teneur en groupes amine primaire atteint environ 1.1 mmol g−1 et le poids moléculaire moyen des hydrolysats de collagène résultants de dépasse pas 2000 g mol−1 (2.0 kDa). Les tendons courts de bétail représentent une source relativement pure et facilement disponible de collagènes et sont, en dépit de leur faible valeur nutritionnelle généralement connue, seulement utilisés comme composant de mélanges nutritifs.
