摘要：

Shear treatment is always employed in the extraction, preparation and research of collagen materials. This study is aimed at investigating the effect of the pre-shearing treatment of neutral bovine tendon collagen solution on the molecular structure, assembly behavior and gel properties of collagen. Rheological and assembly degree (AD) tests showed that with the increase in the shear rate or the extension of shear time during the pre-shearing treatment, the equilibrium moduli and AD of collagen gels that assemble from the pretreated samples gra...
