“…This shows one of the characteristics of extraction using pressurized fluids, i.e., high oil yield in a short extraction time. In addition, the use of propane required a shorter extraction time than extraction with carbon dioxide, due to the high solubility of oil in this solvent . Furthermore, as noted by Fernandes et al, with propane, it is possible to work at relatively lower pressures, which may be more advantageous in relation to lower capital investments and operating costs.…”

“…Propane is a good alternative to CO 2 for the extraction of vegetable oils, due to the greater solubility of lipids in this solvent, as demonstrated by Munuklu et al, Ndiaye et al, Ilic et al, and Hegel et al; it also provides extracts free of solvents and toxic waste. Thus, high yields are obtained in a shorter extraction time, with a smaller volume of solvent and lower pressures than those reported for carbon dioxide .…”

Extraction of macauba kernel oil using supercritical carbon dioxide and compressed propane

et al. 2018

Macauba kernel oil (MKO) was extracted using supercritical CO 2 and compressed propane as the solvent. The influence of temperature (313-353 K for CO 2 and 303-333 K for propane) and pressure (18-22 MPa for CO 2 and 8-12 MPa for propane) on oil yield was investigated, and the results were compared with conventional extraction. A characterization of oil and defatted meal was performed. Temperature and pressure, in the evaluated range, influenced oil yield with the use of CO 2 . For propane, the oil yield was not influenced by the experimental conditions. In the evaluated experimental range, the use of propane and CO 2 provided 100 % and $93 % oil yield compared to conventional extraction, respectively. MKO showed a predominance of saturated fatty acids, among which lauric acid was the major constituent. CO 2 presented greater efficiency in the removal of phytosteroids and tocopherols from the macauba kernel, however, the oil extracted with propane presented longer oxidative stability. Defatted meals presented modified physico-chemical composition and potentiated technological characteristics due to oil removal.

The phase behavior of the system β-carotene− glyceryl trioleate−CO 2 has been investigated using a variablevolume high-pressure cell. The mass fraction of β-carotene in the initial mixture with glyceryl trioleate was 0.1. The gas rich phase was sampled in the pressure range from (25 to 60) MPa at temperatures of (313, 323, and 333) K. The solubilities in dense CO 2 under the investigated conditions were in the range from (4.51•10 −7 to 1.22•10 −5 ) mol•mol −1 for β-carotene and from (0.38•10 −3 to 1.91•10 −3 ) mol•mol −1 for glyceryl trioleate. The results were compared with those found in the literature. The experimental data were correlated using a density based model proposed by Chrastil.

“…Not only SC-CO 2 could be used as a solvent for the extraction of oils and fats, but subcritical propane and supercritical sulphur hexafluoride (SF 6 ) could also be used as solvents in extraction processes. Ilic et al [313] measured the phase behavior of sunflower and soybean oils in propane and SF 6 .…”

In present work a literature review of application of supercritical fluid extraction (SFE) for isolation of nutraceuticals and some other phytochemicals up to December of 2012 is presented. Manuscript provides knowledge of SFE processes and possible aplications of SFE for extraction of bioactive compounds which serve as nutraceuticals. Compounds are classified into groups based on their chemical nature (carotenoids, flavonoids and other phenolic compounds, essential oils, lipids and fatty acids, and alkaloids and other bioactive phytochemicals) and they are reviewed in tabular form along with plant material, from which they were extracted using supercritical fluids.
