ABSTRACT
This study focuses on the production and characterization of electrosprayed cashew gum (CG) microparticles that encapsulate ß-carotene. CG is an inexpensive, non-toxic polysaccharide obtained from Anacardium occidentale trees. Encapsulation of ß-carotene in CG was performed by electrospraying from two emulsion formulations (water oil ratios 8020 and 9010 (v/v)) in which the dispersed phase consisted of ß-carotene dissolved in castor oil, and the continuous phase was a CG aqueous solution. Spherical particles with smooth surface and medium size between 3 and 6 µm were obtained. The particles produced from the 9010 (v/v) emulsion showed a loading capacity of 0.075 ± 0.006 % and a minor amount of extractable ß-carotene, 10.75 ± 2.42 %. ATR-FTIR confirmed the absence of interaction between the particles' components. CG demonstrated to offer thermoprotection, and photoprotection for short periods of time. These results make CG a viable candidate to encapsulate bioactive compounds via electrospraying for agricultural, food and pharmaceutical applications.
