| Résumé : |
The removal of the inter-fibrillar materials viz., proteins, proteoglycans and glycosoaminoglycans (GAGs) are the integral part of conventional liming and bating processes. However, precise quantification on the removal of these interfibrillar materials is still lacking. Hence, in the present work quantification on the removal of protein, proteoglycans and glycosaminoglycans (from goat skins) during liming and bating was attempted. An understanding of the removal of these inter-fibrillar materials precisely could help in developing objective process control measures. Alternative techniques can be developed as it is known that conventional liming processes contribute to more than 60 % of the total pollutionload. The quantification of proteins, proteoglycans and glycoaminoglycans was standardized to suit the requirement for the estimation of the samples obtained from beamhouse process liquors (from liming to bating). It is observed that 3,2 % proteins, 1,2 % proteoglycans and 0,04 % GAGs are released (based on wet salted weight) in the pretanning processes, from liming to bating. removal of proteoglycans during liming has been found to be dependent on the duration of liming process. |
