Supercritical fluid extraction of sunflower seed oil
The effect of ethanol addition to supercritical carbon dioxide (SC-CO2), up to 20%, on sunflower seed oil extraction over the range of 150 to 350 bars and 42 to 80掳C was studied. A nonrecirculating home-made bench-scale system was used as extraction equipment. The oil-SC-CO2-ethanol mixture was reduced to atmospheric pressure in a test tube, where two phases, oil and ethanol, were obtained
Safflower seed oil extraction with supercritical CO 2 at series operational parameters of pressure, temperature, flow rate and particle size was investigated in a bench scale apparatus. The results show that the extraction yields plotted as a function of time are significantly affected by the extraction pressure, flow rate and particle size, but extraction yields plotted versus CO 2 used are
Supercritical CO2 extracted sea buckthorn pulp oil
The effects of supercritical CO2-extracted sea buckthorn seed oil (SBSO) and pulp oil (SBPO) on microcirculation were investigated using two independent experimental models. In the mouse auricular microcirculation model, topical application of SBSO and SBPO on mouse ear, once or twice per day, for three days increased the count of capillary net
Sunflower seed oil was extracted using supercritical CO 2. The effects of pressure, temperature, supercritical CO 2 flow rate and mean particle size on the extraction yield was investigated. The experimental results show that extraction yield increase linearly with time in the early stages of extraction and the extraction process is limited by
Supercritical CO2 extraction of hemp (Cannabis sativa L
In this work, hemp (Cannabis sativa L.) seed oil was produced by extraction with supercritical CO 2 under different extraction conditions (temperature, pressure and time).The objective was to evaluate the influence of extraction conditions on concentration of tocopherols, fatty acids and pigments in hemp seed oil.
Supercritical fluid extraction (SCFE), based on the utilization of a fluid under supercritical conditions, is a technology suitable for extraction and purification of a variety of compounds, particularly those that have low volatility and/or are susceptible to thermal degradation. The interest in SCFE is promoted by legal limitations of conventional solvents for food and pharmaceutical uses.
CO2 Extracts - SunRose Aromatics
CO2-extracts are used as cosmetics ingredients, in perfumes, food and food supplements and in aromatherapy. CO2-extracts are sterile and need no preservation. The highly concentrated supercritical extracts unfold their effects already in low dosages for example as cosmetics ingredients or as bioactive substances in food supplements.
In the extraction of lipid-containing substances with supercritical CO 2 , triglyceride solubilities of up to 20% or more are obtainable by the simultaneous application of temperatures in excess of about 60掳 C. and pressures of at least 550 bar.
Comparative study on the quality of oil extracted from two
Comparative study on the quality of oil extracted from two tucum茫 varieties using supercritical carbon dioxide rind and pulp thickness; diameter and seed mass. An analytical 0.001 g precision scale 2.4 Tucum茫 oil extraction using supercritical co2. The oil extraction experiments using supercritical fluid were performed on homogeneous
This study deals with supercritical CO2 extraction of astaxanthin from Haematococcus pluvialis with ethanol as an entrainer. The effects of pressure, temperature, CO2 flow rate, and the existence of the entrainer concentration on the amount of total extract, the amount of astaxanthin extracted, and the astaxanthin content in the extract were studied. Extractions were carried out at the
Organic Essential Oils, Organic CO2 Extracts, Organic
Our organic extracts are made using new technology that is similar to the ancient method of extracting an enfleurage from precious flower petals. The extraction process uses only certified organic solvents such as fixed oils and alcohol to coax the aromat
