Microencapsulation techniques have been used to prevent carotenoid degradation and preserve their antioxidant activities. In this work, we aimed to encapsulate mamey (Pouteria sapota) and carrot (Daucus carota) carotenoids in mixtures of maltodextrin (10% w/v) and Arabic gum (5 or 10% w/v) by spray-drying. The obtained powders were stored at different temperatures (4 and 25 °C) with or without access to daylight, and changes in color, carotenoid content, and antioxidant activity were analyzed monthly for three months. Moreover, the in vivo antioxidant activities of spray-dried carotenoids were evaluated in Caenorhabditis elegans.
