Modified-release of encapsulated bioactive compounds from annatto seeds produced by optimized ionic gelation techniques.

To compare the encapsulation of annatto extract by external gelation (EG) and internal gelation (IG) and to maximize process yield (% Y), two central composite designs were proposed. Calcium chloride (CaCl) concentration (0.3-3.

Ultrasound-Assisted Extraction of Bioactive Compounds from Annatto Seeds, Evaluation of Their Antimicrobial and Antioxidant Activity, and Identification of Main Compounds by LC/ESI-MS Analysis.

This study evaluated the antimicrobial activity (i.e., against and ) and the antioxidant activity (i.
