The conditions of extracting collagen from skins of sheep, cows, and chickens and compare them


Abstract in English

The aim of this research is the determination of the appropriate conditions for extracting collagen by acidic method from remnants of skins of sheep, cows, and chickens. The results showed that acetic acid is the best among the various organic acids, for extracting collagen of these skins during 48 hours, at concentration of 0.5 M and the ratio, acidic: skin (6:1).
