Description
Collagen hydrolysis transforms tough connective tissues into gelatin through controlled thermal breakdown.
Technical
Extended heating (60-100°C) cleaves collagen's triple helix structure via hydrolysis, yielding gelatin polypeptides and releasing chondroitin sulfate from bone matrix.
Culinary Significance
Creates unctuous mouthfeel and enhances flavor carry in stocks, while extracting valuable nutrients from otherwise inedible tissues.
