Usage in Winemaking: 

Collagen acts in a comparable way to other widely used proteinaceous materials such as gelatine (which is produced from collagen) and isinglass (a fish collagen) to irreversibly bind and remove polyphenolic and tannin materials from wine. These materials precipitate out and are removed along with most of the added collagen.
