| Résumé : |
A protein isolate derived from pea seeds was applied as matrix material for the microencapsulation of béta- carotene, intended for cosmetic application. Experiments were performed to evaluate the possibility of encapsulating béta-carotene in pea protein microsphere by supercritical CO2 (scCO2) technology. The microspheres were prepared by a water-in-oil emulsion technique, where stabilization of the microspheres occured by heat treatment. Parameters like temperature of the emulsion and pH of the protein dispersion appeared to have a marked effect on the formation of microspheres and on the porosity of the matrices. Porous microspheres were successfully applied as carrier materials for β-carotène in scCO2 experiments. With this method no organic solvents were used, and in some cases a free flowing product was obtained. Most important, encapsulation was achieved under mild conditions, thereby preventing the sensitive β-carotene from degradation. This study showed that scC02 technology appeared to be a promising encapsulation technique for β-carotene in pea protein microspheres. |
