ACACIO-CHIRINO, Noel José  and  ZUMALACARREGUI-DE CARDENAS, Lourdes Margarita. Technological processes for obtaining ß-carotene and glycerol from Dunaliella sp. at "Las Cumaraguas" Saltworks. Rev Cub Quim [online]. 2017, vol.29, n.3, pp.341-361. ISSN 2224-5421.

Technological processes were developed for ß-carotene and glycerol extraction from Dunaliella sp. at "Las Cumaraguas" Saltworks. Dunaliella sp. microalgae was characterize. It was established the technological flow of the process from laboratory data; energy balances and necessary energetic calculations were done, in order to select and size the required equipment for a pilot plant scale to produce one ton of ß-carotene. Two possibilities were evaluated: extraction with organic solvents and extraction with supercritical fluids. The procedure showed that ß-carotene and glycerol extractions are possible by means of the presented technological diagram, with 15,4 % of biomass ß-carotene yield and 5 % of biomass glycerol yield, for a conventional extraction and a yield of 70 % for ß-carotene from pigments and 5 % of biomass glycerol yield, for extraction with supercritical fluid.

Keywords : extraction; ß-carotene; glycerol; Dunaliella sp.
