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.

Article Synopsis
  • - Secondary prevention with penicillin is crucial to avoiding repeat acute rheumatic fever and reducing the risk of rheumatic heart disease (RHD), though penicillin allergy reported by 10% of the population complicates this effort.
  • - A comprehensive review of literature revealed no studies specifically addressing penicillin allergy testing in our initial context, but findings from other populations indicated low confirmed allergy rates and very limited severe reactions (less than 1-3 per 1000 treated).
  • - Research on penicillin allergy delabeling showed that direct oral drug challenges resulted in fewer minor allergic reactions compared to skin testing, with no cases of anaphylaxis or fatalities; confirming or clearing penicillin allergies appears safe and has a low risk of adverse

Color is a crucial sensory attribute that guides consumer expectations. 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.

This study aimed to investigate the impact of different microalgal matrices on the bioaccessibility and uptake by Caco-2 cells of carotenoids and chlorophylls. 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.

This brief data article refers to the previous exploration of and biomass about the possibility of using these microalgae species as an unconventional functional food. 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.
