Beschreibung
Zusammenfassung:	Processes are provided that yield high molecular weight collagen without enzymatic or chemical treatment, preserving triple helical content of native collagen. Processing conditions and energy input on animal tissue supply streams can be controlled to obtain collagen compositions with desirable yields and properties, including ratios of denatured and nondenatured collagen with reduced processing time and higher mass throughput. L'invention concerne des procédés qui permettent d'obtenir du collagène de poids moléculaire élevé sans traitement enzymatique ou chimique, préservant le contenu triple hélicoïdal du collagène natif. Des conditions de traitement et une entrée d'énergie sur des flux d'alimentation en tissu animal peuvent être régulées pour obtenir des compositions de collagène présentant des rendements et des propriétés souhaitables, y compris des rapports de collagène dénaturé et non dénaturé avec un temps de traitement réduit et un débit massique plus élevé.
