| Résumé : |
Décorin is a minor proteoglycan (part protein and part carbohydrate) of the skin that is among the key components that undergo changes and removal during conversion of hides to leather. The majority of décorin removal takes place during the dehairing of hides, either traditionally with sodium sulfide or by an alternative oxidative dehairing procedure. The oxidative dehairing method using sodium hydroxide and percarbonate, developed by Marmer and Dudley, was utilized. Further removal of décorin by exposure to proteolytic enzymes during pretanning was explored to study the effects on the quality of leather. Additional removal of décorin was observed when an alkaline protease was added during the reliming stage and pepsin was added during the pickling stage in the pretanning treatments of the hides. More pronounced improvement in leather quality, due to more decorin removed, was observed in oxidatively dehaired hides than those dehaired traditionally with sulfides. As the décorin content decreased, the leather product became softer, more stretchable, and tougher than the control leather tanned without adding proteolytic enzymes. Employing the alternative oxidative dehairing process can solve the problem of sulfide toxicity to the environment while at the same time improving the quality of leather if co-treated with proteolytic enzymes. |
