This study showed that while the effects of different dehairing processes on the structure and stability of monomeric collagen were similar, the effects on the collagen fiber structure were distinct. The basis for tanning and most biomaterials applications is the stabilization of the collagen matrix, thus any changes to the molecular characteristics of hide collagen may be expected to impact these applications. Thus far, the effects of beam-house processes on the molecular characteristics of collagen have received little attention. The tanner evaluates these changes, in terms of impact on tannery costs and quality of leather produced. Economic or environmental issues typically dictate changes in beam-house processes that prepare the hide for tanning. The conversion of animal hides into leather is a multistep process that has evolved more as art form than as science. These hides serve as raw material, first for the leather industry, and then for the gelatin, and biomaterials industries. The US meat industry currently produces approximately 35 million cattle hides annually as its most valuable coproduct.
