Résumé : |
Many authors have reported that biopolymers can be formed from enzymatic crosslinking between dissimilar proteins. It was shown that these products have the advantage of possessing the unique properties of each contributing protein and, at the same time, have the potential for generating innovative products. In this present study, we examined separately the properties of microbial transglutaminase-modified proteins, specifically gelatin, whey, and whey protein isolate (WPI), as well as their enzymatically-combined products. The physical properties and molecular weight distribution of the gelatin biopolymers show that the products had higher melting points, viscosities, and molecular weight distributions, and the degree of crosslinking was enhanced by addition of even small amounts of the secondary protein. There is potential that these products from relatively inexpensive sustainable resources may be used as fillers or as coatings in leather processing. To that end, we carried out a filling experiment, using labeled proteins, and showed that the proteins were evenly distributed throughout the hide and, more importantly, were bound and not removed during the washing steps. |
