| Résumé : |
A gelable protein is isolated during the aqueous magnesium oxide treatment of chromium-containing solid leather waste. For this process to be cost effective, markets have to be identified for these gelatin-like protein products. Technical grade gelatins have many uses, such as in the preparation of adhesives, cosmetics, paints, encapsulating agents, flocculating agents and fireproofing agents. In order to demonstrate that our products compare to technical grade gelatins, the functional properties of the gelable protein were examined; a commercial gelatin product was used as a reference. In a previous study we demonstrated that the gelable protein products isolated from the alkali treatment of chrome shavings had adhesive properties comparable to commercial products. In this present study, ability to form a gel, foamability, capacity to form emulsions, and oil and water absorption properties are examined. A description of methodology to evaluate the properties is reported. The data show that the functional properties of the magnesium oxide extracted gels are comparable to, and sometimes superior to, technical grade gelatins. |
