“…Based on the results, in terms of yield or recovery of essential oil, SC-CO 2 extraction method was considered to be better compared to that of the conventional cold press method. Pioana et al [13] have also compared the yields obtained between wet and dry materials. They reported that the essential oil obtained was about 1.9% v/w from the fresh peel and about 8.4% v/w when dried.…”

“…Various approaches to the extraction of citrus essential oils have been reported. Especially, steam distillation method has been employed for purposes of comparison with SC-CO 2 extraction method [13,14]. Their study showed that extraction method has an influence on the content of aroma compounds and yield of essential oil.…”

“…Several researchers have compared the volatile compounds extracted by SC-CO 2 with the corresponding essential oil collected by steam distillation, the latter being the reference oil. In citrus fruit, Poiana et al [13,26] reported that monoterpene hydrocarbons decreased in SC-CO 2 extracted essential oil with respect to their quantity in obtained by hydrodistillation. Correspondingly, they obtained higher percentage of sesquiterpene, aldehyde, alcohol, and ester in SC-CO 2 extracts based on GC peak areas.…”

Background: Citrus sphaerocarpa Hort. ex Tanaka is one of many popular sour citruses in Japan. Its juice processing peel residues contain a lot of useful compounds including essential oil. Our interests mainly focused on the extraction of this essential oil using supercritical carbon dioxide (SC-CO 2 ), an environmentally benign and generally regarded as safe solvent that has many advantages such as low critical temperature, low viscosity, and easy separation from the extract. In this research, essential oil was extracted from Citrus sphaerocarpa Tanaka peel using SC-CO 2 at extraction temperatures of 313 to 353 K and pressures of 10 to 30 MPa. Results: A maximum yield of 1.55% (by weight of wet sample) was obtained at the temperature of 353 K and the pressure of 20 MPa. The yield obtained by SC-CO 2 method was over 13 times higher than that of the conventional cold-press method. Extracted essential oil was qualitatively analyzed using GC/MS, identifying 49 compounds including several non-polar and weakly polar hydrocarbons such as terpenoid, free fatty acid, and coumarin. Compared to the extracts obtained by the conventional methods, the extracts by SC-CO 2 had lower content of monoterpenes and higher content of oxygenated compounds, sesquiterpenes, which strongly contribute to the aromatic characteristics of the extracts. Auraptene, a bioactive compound was also identified in the SC-CO 2 extract. Conclusions: Kabosu essential oil with a fresh natural fragrance was effectively extracted using SC-CO 2 compared to the conventional extraction method. In addition, it was found that the extract contained higher content of aromatic components that characterize Kabosu. This work provides an important sequential method for the recovery of valuable compounds from citrus fruit waste using an environmentally friendly technique.

“…Thus the physical properties determined were found to conform to the values obtained. [12][13][14][15][16][17] Orange peels were grounded with the mild rpm so as to expose the oil sacs and the pulpy mass weighing 500 g was charged into the extractor and was closed. In the mean time the CO 2 gas was allowed to bring in the supercritical fluid conditions by circulating it in the pre heat exchanger and the process was allowed for half an hour to forty five minutes.…”

Orange peel oil being very useful in foods, flavor, and pharmaceutical industry consumed worldwide. An attempt was made to extract the oil using SC-CO 2 to study the quality, quantity and compositions of the oil. Pressures ranging from 8-15 MPa with temperatures ranging from 28-60℃ were employed. Quality of the oil was analyzed by GC and Capillary GC. Supercritical carbon dioxide was found to extract the oil containing all the low volatile fractions and oil obtained was light pale yellow in color. Shelf life of the oil was found much better than that extracted with conventional techniques. Various pre-treatments were exercised to prolong the good life of peels to study the impact on their physical properties and quality along with the yields. Alkaline treatment of the orange peels reveals some important observations in the extractions of constituents.

In recent years, essential oils have received a growing interest because of the positive health effects of their novel characteristics such as antibacterial, antifungal, and antioxidant activities. For the extraction of plant-derived essential oils, there is the need of advanced analytical techniques and innovative methodologies. An exhaustive study of hydrodistillation, supercritical fluid extraction, ultrasound- and microwave-assisted extraction, solid-phase microextraction, pressurized liquid extraction, pressurized hot water extraction, liquid-liquid extraction, liquid-phase microextraction, matrix solid-phase dispersion, and gas chromatography (one- and two-dimensional) hyphenated with mass spectrometry for the extraction through various plant species and analysis of essential oils has been provided in this review. Essential oils are composed of mainly terpenes and terpenoids with low-molecular-weight aromatic and aliphatic constituents that are particularly important for public health.
