<p>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.</p> |
