- Abstract
Technological properties of plant tanning extracts are defined in terms of their quality. Standard method for determining the quality of tanning materials adopted by the all-Union unified method is based on the property of leather powder to adsorb tannins. Since the production of leather a powder was terminated it is necessary to find the alternative method. Different methods of determination of tanning matter quality were compared. The possibility to use the collagen instead of leather powder for evaluation of quality of tannins was shown experimentally
