The rheological properties of collagen comprise one of its most important characteristics in terms of the casing extrusion process. However, it is unclear which level of the collagen structure significantly affects the rheological behaviour of collagen gels. This study concerned the comprehensive analysis of two differing bovine collagen gels with glycerol intended for the extrusion of casings focusing on their chemical compositions and structures and their effects on the rheological properties. Although only minor differences were determined in terms of the primary and secondary structures, significant differences were discovered concerning the rheological properties. The differences were found to correlate with the differing directionality of the collagen fibril bundles. In conclusion, the tertiary and quaternary structures of collagen affect its rheological properties more significantly than do its primary and secondary structures. These results suggest the importance of these two collagen structure levels in terms of the mechanical behaviour of collagen materials.
