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...

Optimisation of Supercritical Fluid Extraction of Astaxanthin from Penaeus Monodon Waste Using Ethanol-modified Carbon Dioxide

Some studies demonstrated that astaxanthin surpasses the antioxidant benefits of beta-carotene, zeaxanthin, canthaxanthin, vitamin C, and vitamin E. Penaeus monodon (Tiger shrimp) is one of the most valuable traded crustacean products in which astaxanthin can be found in its by-products. The extraction of thermolabile compound like carotenoids at lower temperatures through supercritical carbon ...

In-line catalytic purification of carbon dioxide used in analytical-scale supercritical fluid extraction

Supercritical fluid extraction analyses are often compromised by trace impurities present in the solvent carbon dioxide. These impurities, commonly used as lubricants in the specialty gas industry, can produce significant background levels, increasing limits of detection and quantification. This problem is especially severe when electron capture detection (ECD) is used for trace concentrations ...
