Procédé pour la préparation de collagène et produits obtenus

A process for the preparation of collagen and obtained product

Verfahren zur Herstellung von Kollagen und daraus erhaltene Produkte


A process for the preparation of undenaturated tri­ple helix collagen, starting from animal tendons or cutis, by extraction with diluted organic acids, precipitation with salts, optional gelation and/or lyophilization, tangential filtration. The obtained collagen shows favourable purity cha­racteristics, is not allergenic and more effective in the healing processes than collagens obtained by known methods.
