| Résumé : |
We recently demonstrated that fillers could be formed inside leather when gelatins alone or mixed proteins, such as gelatin and casein or gelatin and whey, were added to wet blue that had been pretreated with microbial transglutaminase. To monitor these reactions, we had added fluorescently labeled proteins to stock solutions and examined the resultant filled leather using a microscope equipped with an epi-fluorescent attachment. In this present study, based on our understanding of the effect that enzyme modification will have on physical properties of crosslinked proteins, we polymerized potential filler products prior to their addition to the wet blue. We characterized the products with respect to their physical properties and molecular weight distribution (degree of polymerization). These products were applied to wet blue and evaluated, again using fluorescent labels to monitor their filling capability. It was shown that the proteins were evenly distributed throughout the hide and, more importantly, were not removed during the washing steps. Micrographs showing the location of fillers using fluorescent labels are presented. |
