“…The total phytosterol content of UAAE‐extracted oil was significantly lower ( p < 0.05) than solvent‐ and SCO 2 ‐extracted oils (Table ). Previous study reported the total phytosterols of Araucaria angustifolia seed oil obtained by subcritical propane extraction (8.78–9.33 g kg −1 ) were greater than solvent extraction (5.99 g kg −1 ) . However, a similar trend was not observed in the current study.…”

The quality characteristics, bioactive phytochemicals, volatile compounds, and antioxidant capacities of virgin avocado oil extracted using a couple of green methods, namely, subcritical CO2 extraction (SCO2) and ultrasound‐assisted aqueous extraction (UAAE), are compared with the oil extracted using the conventional solvent extraction. Results indicate the quality properties of avocado oil are unaffected by extraction methods. The total phenolic content of avocado oil is in the range of 111.27–130.17 mg GAE/100 g and the major phytosterol is β‐sitosterol (1.91–2.47 g kg−1). Avocado oil extracted using SCO2 exhibits two to four times greater levels of α‐ and γ‐tocopherols than solvent extraction and UAAE. The volatile components associated with nutty and grassy flavors are only detected in avocado oil extracted under low‐temperature extraction conditions such as SCO2 and UAAE. Based on the antioxidant capacity tests, avocado oil obtained by SCO2 exhibits the strongest antioxidant capacity compared with solvent extraction and UAAE. Practical Applications: Virgin avocado oil extracted using subcritical CO2 method exhibits superior levels of tocopherols content and antioxidant capacity than ultrasound‐assisted aqueous and conventional solvent methods. Subcritical CO2 is a promising oil extraction technique to obtain solvent‐free avocado oil with potential uses in functional foods and health care products. Virgin avocado oil is extracted using subcritical CO2 and ultrasound‐assisted aqueous techniques. The properties of the oil are compared with conventional solvent‐extracted oil. The percentage of antioxidant activity decreases in the order of SCO2‐extracted oil > solvent‐extracted oil > UAAE‐extracted oil.

“…The edible part of the seedscontains about 50% moisture. The contents of ash, crude protein, total lipids, total fibers and other carbohydrates are 1.50%, 3.42%, 1.67%, 1.29% and 48.42%, respectively (da Silva et al, 2016). Among carbohydrates, starch is the main component,comprising around 31-36%, averaging 30% amylose in the raw seed (BelloPérez et al, 2006;Conforti and Lupano, 2007;2008).…”

“…Glucose is the most common sugar, followed by fructose and sucrose. Thirteen fatty acids were recently identified in the edible seed (da Silva et al, 2016). The main fatty acids are linoleic acid (18:2n-6), oleic acid (18:1n-9) and palmitic acid (16:0).…”

“…(Duba & Fiori, 2015;Martinez, 2008). Based on previous studies, this supercritical CO 2 extraction method could decrease the degradation of bioactive compounds, leading to a final extracted product without toxic residuals (Benito-Román, Rodríguez-Perrino, Sanz, Melgosa, & Beltrán, 2018;da Silva et al, 2016;Duba & Fiori, 2019;Mariod, Matthaus, & Ismail, 2011).…”

Response surface methodology (RSM), based on a central composite design, was used to simultaneously predict the optimal condition for oil extraction of Assam tea seeds via supercritical CO2 extraction method. The established regression mathematical model oil extraction was good enough for the prediction of experimental results (e.g., crude oil yield). The optimized extraction condition (50°C under 220 bar for 4 hr) providing the best quality of oil has high percentage of crude oil yield and oil recovery, low values of acid, free fatty acids, peroxide, and thiobarbituric acid reactive substances (TBARS), high values of iodine and saponification, and high phenolic content and low values of DPPH (IC50) and ABTS (IC50). Flavonoid, tannin, and saponin were detected in the extracted oil samples. In addition, major fatty acids in the extracted oil were oleic, linoleic, and palmitic acids. Practical applications Supercritical CO2 extraction can potentially be used for the extraction of oil from Assam tea seeds (Camellia sinensis var. assamica), providing a high oil yield. Assam tea seed oil obtained by supercritical CO2 extraction had a high antioxidant activity. The main fatty acids were oleic acid, linoleic acid, and palmitic acid. The obtained oil contained flavonoids, tannins, and saponins and is, therefore, a potential source of active and functional compounds used in the food industry, the production of food supplements and the pharmaceutic and cosmetic industries.
