Abstract
Microalgae are an interesting source of natural pigments that have valuable applications. However, further research is necessary to develop processes that allow us to achieve high levels of carotenoid recovery while avoiding degradation. This work presents a comprehensive study on the recovery of carotenoids from several microalgae genera, optimizing carotenoid extraction using alkaline saponification at various temperatures and KOH concentrations. Results show that I. galbana requires a temperature of 60â¯Â°C and <10% KOH, N. gaditana and K. veneficum require 60â¯Â°C and no saponification, P. reticulatum requires 40â¯Â°C and 10% KOH, T. suecica and H. pluvialis require 25â¯Â°C and 40% KOH while C. sp. and S. almeriensis require 80â¯Â°C and 40% KOH. The influence of the solvent on carotenoid recovery was also studied. In general terms, an ethanol:hexane:water (77:17:6â¯v/v/v) mixture results in good yields.
