SUPERCRITICAL FLUID EXTRACTION WITH CARBON DIOXIDE AT DIFFERENT PRESSURES

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

black nightshade oil extraction using supercritical fluid carbon dioxide

black nightshade is a weed plant that grows abundantly in most parts of iran. in this study, central composite response surface method to investigate the effect of temperature 35-55 °c and pressures 170-350 bar during the dynamic time of 120 min, the particle size of 150 microns and flow rate of 3 liters per minute on the efficiency of oil extracted from the fruits of black nightshade and optim...

Paprika (Capsicum annuum) oleoresin extraction with supercritical carbon dioxide.

Paprika oleoresin was fractionated by extraction with supercritical carbon dioxide (SCF-CO(2)). Higher extraction volumes, increasing extraction pressures, and similarly, the use of cosolvents such as 1% ethanol or acetone resulted in higher pigment yields. Within the 2000-7000 psi range, total oleoresin yield always approached 100%. Pigments isolated at lower pressures consisted almost exclusi...

Study of the stability of two different fish oils obtained by extraction with supercritical carbon dioxide

During the last years the evidence of the nutritional benefits of polyunsaturated fatty acids (PUFA), especially omega-3 fatty acids, in the human body has become established. Moreover, the nutrition experts have recently recommended to increase the PUFA consumption in order to maintain an omega-6/omega-3 ratio between 5:1 and 10:1 in the diet [1]. Fish is the major dietary source of ω-3 PUFA; ...

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...
