“…Palmitoleic acid (C16:1) and α-linoleic acid (C18:3n3) were found among the unsaturated fatty acid composition of Mayten tree seed oil ( Figure 1 ), at higher levels than are found in sesame, sunflower, and rice brain [ 50 ]. Canola seed oil contains 3.4 g of palmitic acid per 100 g of oil [ 51 ], whereas the palmitic acid contents of Mayten tree seed oil were two-fold higher that in canola seed oil.…”

The Mayten tree (Maytenus boaria Mol.), a native plant of Chile that grows under environmentally limiting conditions, was historically harvested to extract an edible oil, and may represent an opportunity to expand current vegetable oil production. Seeds were collected from Mayten trees in north-central Chile, and seed oil was extracted by solvent extraction. The seed oil showed a reddish coloration, with quality parameters similar to those of other vegetable oils. The fatty acid composition revealed high levels of monounsaturated and polyunsaturated fatty acids. Oleic and linoleic acids, which are relevant to the human diet, were well represented in the extracted Mayten tree seed oil. The oil displayed an antioxidant capacity due to the high contents of antioxidant compounds (polyphenols and carotenoids) and may have potential health benefits for diseases associated with oxidative stress.

“…Besides, the n ‐6/ n ‐3 ratio was higher than that found in canola oils produced by chemical and physical refining (1.82) reported by Szydłowska‐Czerniak et al (2019). Differences in fatty acid concentrations in oils can be related to the different extractive methods, canola hybrids, sowing dates (Confortin et al, 2019).…”

The aim of this work was to refine expeller‐pressed crude canola oil by pilot scale liquid–liquid extraction with hydrated ethanol as solvent. Quality indices were determined, and shelf life was estimated in the accelerated test. The scale projection was performed based on the results of the pilot scale. The experimental device operates in a batch process with 89.6% yield deacidification and an average of 4.4 contacts per assay. In this process, without bleaching and deodorization steps, physicochemical parameters were according to the Codex Alimentarius standards, except moisture. In this way, it will be necessary to apply nonthermal techniques to remove water. The major fatty acids identified were oleic and linoleic acid and the absence of trans fatty acids. For the shelf life, the refined oil presented free fatty acids 0.28% and peroxide value 12.65 meq O2 kg−1 after 24 hr at 65°C. The pilot scale results showed that the technique is suitable to produce edible oils. A liquid–liquid extractor was designed for industrial scale with the total volume will be 12,000 L. To process 6 tons of crude canola oil per day, the unit will be able to produce 1.3 thousand tons per year of refined canola oil. Practical applications After acid degumming, canola oil was submitted to liquid–liquid extraction, using ethanol as solvent. As a result, two traditional steps of refining vegetable oils have been eliminated: bleaching and deodorization. This fact directly impacts on physical space of industry, maintenance of equipment and need for operators. Trans fats were not detected in canola oil, pointing that the technique is efficient in the production of healthier oils, with less environmental impact.

“…The experimental assays of SFE-CO 2 were performed on a laboratory scale equipment, using carbon dioxide (CO 2 ) as the solvent. Details of the apparatus and procedure have been described by Confortin et al (2019). For the extractions, approximately 10 g of samples (dried and milled) were used for each matrix and the CO 2 flow rate was 4 g/min.…”

Solanum viarum Dunal belongs to the Solanaceae family and it is considered to be a grazing weed toxic to cattle. In this study, ultrasound-assisted extraction (UAE) and supercritical CO 2 extraction (SFE-CO 2 ) were applied to evaluate the extraction yield and chemical composition of fruits and roots matrices of Solanum viarum Dunal. A hydroalcoholic solution (60% ethanol/40% water, v/v) was the solvent used for UAE. For comparisons, extractions with Soxhlet and maceration were carried out. For SFE-CO 2 , the highest yield was obtained at 60°C and 250 bar. For UAE, the highest yield was obtained at an ultrasound intensity of 75.11 W/cm 2 and pulse cycle of 0.93. The techniques seem to be efficient for the extraction of chemical compounds, indicating a large number of bioactive compounds. The major compounds are 1,2-benzenedicarboxylic acid, quinic acid, octadecenoic acid, and solasodine. The results highlight the application of UAE to recover compounds from vegetal matrices, since it presented higher yields and more chemical constituents when compared with other techniques.
