although current enzyme technology is still primarily dependent upon proteolytic enzymes, better characterization and more sensitive methods of control can provide the basis for using these products more selectively during soaking and bating. there is now also the opportunity of using selected proteases during chemical unhairing/ liming to improve beamhouse processing, based on a clearer understanding of the opening-up process and the role of proteoglycan commercial trials and production runs have confirmed the viability of enzyme assisted chemical unhairing under practical conditions. the range of key options available to the tanner are shortening of liming time, increased opening-up of the fiber structure and the production of softer leather, improved pulping and the production of cleaner grains, reduction of sulfide requirement, and increased area yields 79 refs
