| Résumé : |
Gelatin has been extensively used in simple and complex coacervation technologies to microencapsulate drugs, essential oils, perfumes, and other materials. The aim of this work was to use gelatin isolated from chromium-containing solid tannery waste to demonstrate the potential application of this product in microencapsulation. As a model, an anionic semi-synthetic fatliquor, typically used in the tanning industry, was microencapsulated by complex coacervation using gelatin and acacia. The behaviors of commercial gelatins (75 and 225 g Bloom) and alkali- or enzyme-extracted gelatins from chrome shavings were compared. The microencapsulation process was repeatable and no significant differences were found between commercial and extracted gelatins. Sieving analysis showed similar size particles in the different samples, and microscopic analysis showed that the particles had a tendency to aggregate. The marketability of a product with such a potential application should encourage the industry to recycle tannery wastes instead of dumping them into landfills. |
