A biorefinery from Nannochloropsis sp. microalga – Extraction of oils and pigme...
Nobre, Beatriz P.; Villalobos, Fidel; Barragan, Blanca E; Oliveira, A. C.; Batista, Ana Paula; Marques, Paula Alexandra; Mendes, Rui L.; Sovová, H.The microalga Nannochloropsis sp. was used in this study, in a biorefinery context, as biomass feedstock for the production of fatty acids for biodiesel, biohydrogen and high added-value compounds. The microalgal biomass, which has a high lipid and pigment content (mainly carotenoids), was submitted to supercritical CO2 extraction. The temperature, pressure and solvent flow-rate were evaluated to check their ef...
Supercritical Extraction of Lycopene from Tomato Industrial Waste with Ethane
Nobre, Beatriz P.; Gouveia, L.; Matos, Patricia G. S.; Cristino, Ana F.; Palavra, António F.; Mendes, Rui L.Supercritical fluid extraction of all-E-lycopene from tomato industrial wastes (mixture of skins and seeds) was carried out in a semi-continuous flow apparatus using ethane as supercritical solvent. The effect of pressure, temperature, feed particle size, solvent superficial velocity and matrix initial composition was evaluated. Moreover, the yield of the extraction was compared with that obtained with other su...
