Using proteomics to compare the molecular structures of sulfide and permeate-depilated sheepskins
An environmentally friendly method using real or artificial bovine milk permeate to both depilate and preserve sheepskins has been reported which completely and cleanly removed the wool from the hair follicle and had no detrimental effects on the skin. A proteomic analysis, assessing the relative abundance of proteins in matched permeate-depilated and chemically depilated (sulfide) sheepskins, showed variations in the levels of specific collagen types in the skin's basement membrane and other proteins associated with the follicles. These findings were corroborated by biochemical analyses of matched permeate depilated and raw skin samples, and provide clues to the mechanism of non-invasive and complete depilation. They also support the observation that permeate-depilated skins were smoother than their sulfide-depilated counterparts and resulted in leather with a superior surface.
