Supercritical Fluid Extraction of Carotenoid from Microalgae with Projected Thermodynamic Models (RESEARCH NOTE)

Carotenoid Pigments: Supercritical Fluid Chromatography

Carotenoids are one of the main classes of natural pigments and are found in a large number of fruits and vegetables (oranges, tomatoes, carrots) and in leaves where their presence is masked by chlorophylls until autumn. They are also found in some animal products (eggs, milk) and seafoods. Typically, carotenoids contain eight isoprenoid units bonded such that the units are reversed at the cent...

Supercritical Fluid Extraction+supercritical Fluid Chromatography

high pressures also requires special equipment. In summary, both RESS crystallization and SAS crystallization appear to be promising methods for generating supersaturation and therefore represent alternatives to conventional crystallization. Such alternatives may prove attractive in applications such as polymer and pharmaceutical processing, or in particle design for drug delivery. It is possib...

Modeling of the Kinetics of Supercritical Fluid Extraction of Lipids from Microalgae with Emphasis on Extract Desorption

Microalgae contain valuable biologically active lipophilic substances such as omega-3 fatty acids and carotenoids. In contrast to the recovery of vegetable oils from seeds, where the extraction with supercritical CO₂ is used as a mild and selective method, economically viable application of this method on similarly soluble oils from microalgae requires, in most cases, much higher pressure. This...

Lipid Extraction from Wheat Flour Using Supercritical Fluid Extraction

Cereal Chem. 81(6):693–698 Environmental concerns, the disposal cost of hazardous waste, and the time required for extraction in current methods encouraged us to develop an alternate method for analysis of wheat flour lipids. Supercritical fluid extraction (SFE) with carbon dioxide has provided that medium and the method is fully automatic. Crude fats or nonstarch free lipids (FL) were extracte...
