SUPERCRITICAL CARBON DIOXIDE EXTRACTION OF CITRONELLA OIL FROM CYMBOPOGON WINTERIANUS USING TAGUCHI ORTHOGONAL ARRAY DESIGN

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

EXTRACTION OF CITRONELLA (Cymbopogon nardus) ESSENTIAL OIL USING SUPERCRITICAL CO2: EXPERIMENTAL DATA AND MATHEMATICAL MODELING

Citronella essential oil has more than eighty components, of which the most important ones are citronellal, geranial and limonene. They are present at high concentrations in the oil and are responsible for the repellent properties of the oil. The oil was extracted using supercritical carbon dioxide due to the high selectivity of the solvent. The operational conditions studied varied from 313.15...

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...

Supercritical Carbon Dioxide Extraction of Borage Seed Oil

The oil from the seeds of Borago officinalis L. (borage) is a major commercial source of ?-linolenic acid. The fatty acid has a great potential therapeutic value in the treatment of several diseases. In the present work the efficiency of high pressure extraction of borage seed oil containing ?linolenic acid in high concentrations was investigated. Extraction was performed by semicontinuous flow...

Supercritical carbon dioxide extraction of carotenoids from carrot using canola oil

208 The natural food colorants, carotenoids, are of great importance to human health. The scientists at Department of Agricultural, Food and Nutritional Science, University of Alberta, Canada enhanced the efficiency of SC-CO 2 extraction of carotenoids from carrots, by using canola oil as a continuous cosolvent. The carotenoid content of the starting material was determined by traditional solve...
