Native collagen is a high-quality, pure protein derived mainly from bovine and porcine hide and bone, but also from poultry. Native materials are subject to stringent quality control, and suppliers are carefully audited to assure the highest quality family of collagen ingredients—including collagen, gelatin and collagen peptides.
The key physical properties of collagen are gel strength/bloom, viscosity, particle size, isoelectric point, melting properties, heat stability and dissolution. It is important to choose the right collagen ingredient for the desired purpose. Measurement and specification of these properties is key.
