Phytoene-rich first described C. sorokiniana biomass was used, both fresh, freeze-dried, and encapsulated. The ideal dose of norflurazon (1 µg/mL) was selected to block the carotenoid pathway at the level of phytoene desaturase and induce the accumulation of phytoene in C. sorokiniana. A mill pre-treatment allowed a higher recovery of carotenoids compared to non-milled samples, in both the freeze-dried and encapsulated matrices. 2-Methyloxolane provided a higher total carotenoid content (4.75–5546.96 µg/g) compared to the other solvents tested in all the matrices, proving a promising bio-based solvent to replace traditional organic ones for the extraction of microalgal carotenoids.}, organization = {This study was financially supported by grants PID2019-110438RB- C21 (NEWCARFOODS) and PID2019-110438RB-C22 (BESTALGAE4CAROT), funded by MCIN/AEI/ 10.13039/501100011033.
