| Résumé : |
In this new article of the series "Hair saving unhairing process" the development of the theme of enzyme unhairing is initiated. It gathers three curious features : it has been extensively studied by many researchers in different countries during the last century, it is scarcely used in the industry and it still keeps the attraction, as a challenge, to keep on calling together the interest of research groups that find in this process the ideal unhairing process.
Enzymatic unhairing will be the ideal unhairing process when the enzyme specificity is guided specially towards the components of the epidermis system, its action on the structured proteins—especially the collagen—is minimized or avoided, and when leather is developed with desirable properties.
The aim of this first article on the enzyme unhairing is to show—with no intention of being exhaustive—the research evolution of those work groups that showed relevant activity, adding in each of the sections comments and complementary suggestions from other work. Experimental studies and theoretical speculation at the Leather Research and Development Centre (CITEC) on the hair—saving unhairing process, particularly enzyme unhairing, tries to contribute to better knowledge on mechanisms (diffusive and chemical) involved in the unhairing, with the purpose of proposing the design of enzyme preparations to bring us closer to ideal unhairing.
The introduction of the research evolution on the enzyme unhairing, the behaviour of enzyme preparations on different substrates, the mechanisms that can take place in the process and the desirable/undesirable properties of resultant leather come before the presentation of the experimental results that are being obtained at CITEC. Thus, we will show in a further article, the results of the characterisation of commercially available enzyme preparations through the evaluation of proteolytic activities against a representative substrate of animal hide components and the activation inhibition effects that an unhairing system has on enzymes. |
