The design and development of nanoparticle- and microparticle-based delivery systems incorporating carotenoids into carrier materials offers multiple advantages, including enhancing the bio-efficacy of these compounds due to improving their bioaccessibility and bioavailability. This study introduced pitanga saponified carotenoid extract (PSCE) and pitanga non-saponified carotenoid extract (PSCE) in a 12 % zein/1 %PEO solution and electrospun for fiber production. Then, the fibers were characterized, and their bioaccessibility and bioavailability were also evaluated.

A high-performance pequi carotenoid extraction process was developed using ionic liquid-based ethanolic solutions and a factorial design strategy to search for a potential substitute for the artificial azo dye yellow tartrazine. All-trans-antheraxanthin was identified with HPLC-PAD-MSn for the first time in pequi samples.

In this way, the microalgal ingredients/products (whole dry biomass [WDB], whole ultrasonicated paste [WUP], and liposoluble pigment emulsion [LPE]) obtained from Chlorella vulgaris and Arthrospira platensis were submitted to in vitro simulated digestion. Apical uptake of pigments in micelles generated during the simulated digestion by Caco-2 human intestinal cells was determined.

Data on chemical composition, fatty acids, volatile compounds, and carotenoid profiles were determined. In parallel, are provided the antioxidant capacity (reducing capacity - RC and reactive oxygen species deactivation - ORAC) of aqueous, lipophilic, and carotenoid extracts isolated from microalgae biomass.
