“…Linoleic acid was the predominant fatty acid in the oil from both melon seeds followed by oleic, palmitic and stearic acids with concentrations of 64, 16, 8.5 and 6%, respectively. These results were in good agreement with that of Norulaini et al, (2009) who studied the effects of supercritical carbon dioxide extraction parameters on virgin coconut oil and they reported that the composition of the fatty acid in the extracted oil varied, based on the extraction conditions. While Sanchez-Vicente et al, (2009) found no change in terms of fatty acid distribution in all the extracted peach seed oils at the conditions of acid (MUFA) and 65.92% of polyunsaturated fatty acid (PUFA).…”

other hand SFA decreased from 16.35 to 13.91% in GLO 1 st fraction, and MUFA decreased from 17.50 to 15.57% in GLO 2 nd fraction, while PUFA increased from 66.15 to 70.52% in GLO 3 rd fraction. The different fractions of the two oils showed high antioxidant activity in reducing the oxidation of β-carotene in beta-carotene bleaching assay (BCB) and the quenching of 1,1-diphenyl-2-picrylhydrazyl (DPPH).

“…[75] DCM and ethyl acetate were the most popular solvents used. [85] Because of environmental issues such as ozone depletion and health risks associated with these conventional www.chemsuschem.org organic solvents, a drive for a new decaffeination method was initiated. The use of CO 2 for decaffeination was first commercialized in 1970s by cafØ HAG and General Foods in Germany, after a patent by Zosel.…”

“…CO 2 is widely used as an extraction solvent for various applications. These include decaffeination of coffee and tea, [75][76] production of hops extracts for the brewing industry, [77][78] recovery of flavors and aromas from herbs and spices, [79][80] nicotine extraction from tobacco, [81][82] extraction and fractionation of edible oils, [83][84][85] and removal of contaminants as a cleaning procedure. [86][87] The effectiveness of the extraction is highly dependent on the kinetic extraction properties of the raw materials, solvent strength, and the operating conditions.…”

As a carbon-based life form living in a predominantly carbon-based environment, it is not surprising that we have created a carbon-based consumer society. Our principle sources of energy are carbon-based (coal, oil, and gas) and many of our consumer goods are derived from organic (i.e., carbon-based) chemicals (including plastics, fabrics and materials, personal care and cleaning products, dyes, and coatings). Even our large-volume inorganic-chemicals-based industries, including fertilizers and construction materials, rely on the consumption of carbon, notably in the form of large amounts of energy. The environmental problems which we now face and of which we are becoming increasingly aware result from a human-induced disturbance in the natural carbon cycle of the Earth caused by transferring large quantities of terrestrial carbon (coal, oil, and gas) to the atmosphere, mostly in the form of carbon dioxide. Carbon is by no means the only element whose natural cycle we have disturbed: we are transferring significant quantities of elements including phosphorus, sulfur, copper, and platinum from natural sinks or ores built up over millions of years to unnatural fates in the form of what we refer to as waste or pollution. However, our complete dependence on the carbon cycle means that its disturbance deserves special attention, as is now manifest in indicators such as climate change and escalating public concern over global warming. As with all disturbances in materials balances, we can seek to alleviate the problem by (1) dematerialization: a reduction in consumption; (2) rematerialization: a change in what we consume; or (3) transmaterialization: changing our attitude towards resources and waste. The "low-carbon" mantra that is popularly cited by organizations ranging from nongovernmental organizations to multinational companies and from local authorities to national governments is based on a combination of (1) and (2) (reducing carbon consumption though greater efficiency and lower per capita consumption, and replacing fossil energy sources with sources such as wind, wave, and solar, respectively). "Low carbon" is of inherently less value to the chemical and plastics industries at least in terms of raw materials although a version of (2), the use of biomass, does apply, especially if we use carbon sources that are renewable on a human timescale. There is however, another renewable, natural source of carbon that is widely available and for which greater utilization would help restore material balance and the natural cycle for carbon in terms of resource and waste. CO(2), perhaps the most widely discussed and feared chemical in modern society, is as fundamental to our survival as water, and like water we need to better understand the human as well as natural production and consumption of CO(2) so that we can attempt to get these into a sustainable balance. Current utilization of this valuable resource by the chemical industry is only 90 megatonne per year, compared to the 26.3 gigatonne CO(2) generated annually by c...

“…The high cost of organic solvents, increasingly stringent environmental regulations, and new requirements of the medical and food industries for ultra-pure and high added value products have increased the need for the development of new and clean technologies for the processing of food products (Mohamed and Mansoori, 2002). Supercritical carbon dioxide (SC-CO 2 ) extraction has attracted considerable attention in recent years as a promising alternative to conventional solvent extraction and mechanical pressing for extracting oils and other materials as it offers a number of advantages, including a lack of solvent residue and better retention of aromatic compounds (Norulaini et al, 2009;Zaidul et al, 2006Zaidul et al, , 2007aHerrero et al, 2006).…”

a b s t r a c tSupercritical fluid extraction (SFE) offers an alternative method to conventional extraction of fatty acids. SFE was developed for analytical application in the mid-1980s in response to the desire to reduce the use of organic solvents in the laboratory environment, and it is now becoming a standard method for the extraction, fractionation, refinement and deodorization of lipids or essential oils containing sample matrices at the industrial scale. This paper reviews applications of supercritical fluid technology in fatty acid/lipid extraction using carbon dioxide. Carbon dioxide is an ideal supercritical fluid because of its environmentally benign, non-toxic, non-flammable, non-polluting, recoverable characteristics and its ability to solubilise lipophilic substances. A summary of commercial applications and examples of recent developments of SFE in the food processing industry are also reviewed.
