Resumo

Bixin is the major carotenoid in the seed of the Annatto plant (Bixa orellana L.). The aim of this study was to obtain extracts containing bixin from seeds that had been partially defatted by supercritical fluid extraction. Pressurized liquid extraction (PLE) and low-pressure solvent extraction (LPSE) methods were used, and the effects of the solvent, temperature, pressure, solvent mass to feed mass (S/F) ratio and ultrasonication were evaluated for the global yield (X-0(%)) and the bixin yield (BY(%)). Extraction conditions producing high yields of bixin were established for both the PLE and LPSE methods. Analysis of variance was used to examine the influence of the individual extraction variables in LPSE and PLE. For LPSE; significant effects were found for solvent, temperature, and the interactions of temperature with solvent and temperature with S/F. Solvent was the only variable that significantly affected X-0(%) and BY(%), for PLE. While ultrasonication did not significantly affect X-0(%) or BY(%), scanning electron microscopy analysis revealed structural changes in the vegetal matrix following this treatment.
