“…High oil recovery since the solvent used was polar. Cornelio‐Santiago et al (2022) used PLE in intermittent process with isopropanol to extract oil from pequi and sacha inchi almonds rich in β‐sitosterol. The extraction with pressurized isopropanol in 27 min allowed high oil recovery (92.98% for pequi and 86.55% for sacha inchi) under the same conditions for Brazil nut oil extraction.…”

This research demonstrates pressurized liquid extraction (PLE) in an intermittent process in obtaining soybean oil using less solvent than conventional extraction. Temperature (T), solvent rinse volume (VS), contact time between the solvent and the matrix (St) in each cycle and number of cycles (C) were screened. Yield, fatty acids profile (FAs), and triacylglycerols were evaluated. After preliminary testing, T and St were tested for yield while VS, C, and P were fixed at 60% of total volume of the fixed bed extractor, 3 cycles, and 10.34 MPa respectively. The highest oil recoveries were 94.40% (85°C, 13 min, with hexane) and 86.16% (80°C, 12 min, with ethanol). The mass ratio of solvent/feeds resulted in a yield increase of 1.47% (hexane) and 3.99% (ethanol). The concentration of β‐sitosterol (≤182.78 mg/100 g of oil, hexane; ≤71.64 mg/100 g of oil, ethanol) and the fatty acid profile were not affected by the different solvents or process. The main fatty acids were linoleic (≤51.12%, ethanol; ≤40.31%, hexane) and oleic (≤24.98%, ethanol; ≤26.62%, hexane). The main triacylglycerols identified were LLO, LLL, and OOL. The results indicate that soybean oil can be obtained by a new process that uses a safe and renewable solvent, indicating that PLE in an intermittent process can replace conventional extraction without changing the main characteristics of the oil, with good yield using less solvent.Practical applicationsThe practical application of this research is related to the possibility of demonstrating the feasibility of PLE in obtaining soybean oil using pressurized ethanol. The solvent used in most oilseed extraction plants is commercial hexane, a toxic and non‐renewable solvent. The experiments were carried out with pressurized hexane to demonstrate the economy of solvents and compare with the results obtained when pressurized ethanol was used as a solvent. The ethanol study aimed to show high extraction yields, even using a polar solvent in soybean oil extraction. High yields and oil characterization showed that it is possible to use a green and clean technology to obtain vegetable oils.

Woody edible oils are a type of vegetable oil. Woody edible oils like olive oil have greater quantities of unsaturated fatty acids (UFAs), particularly essential FAs, as well as vitamin E, phytosterols, and other nutrients that are becoming more vital in human health. As a result, finding high‐quality woody oil resource plants is critical to ensuring enough edible oil supply. As six novel woody crops, Paeonia suffruticosa, Plukenetia volubilis, Acer truncatum, Olea europaea, Camellia sinensis, and Camellia oleifera are characterized by high oil production, widespread cultivation, adaptability, and various active ingredients. The six woody crop oils contain UFAs (e.g., α‐linolenic acid, oleic acid, and linoleic acid), vitamin E, polyphenols, phytosterols, and so forth. The presence of these active ingredients confers anti‐inflammatory, antioxidant, cholesterol and lipid metabolism regulating, blood lipid lowering, immune boosting, memory improving, intestinal flora regulating, and other properties to the oils, which are beneficial to body health. This article examined in depth the seed resources, FA composition, active component kinds, active ingredient efficacy mechanism, and physiological impacts of these six novel woody crop oils. These developments lay a solid platform for further study and development of these woody oil crops.

Pequi is a natural source of bioactive compounds with wide versatility for fresh or processed fruit consumption, but it is still little explored economically. Functional foods are the subject of diverse scientific research since, in addition to being nourishing, they contain bioactive compounds capable of promoting several benefits to the human body. Pequi is a fruit species native to the Brazilian Cerrado, which is rich in oil and has components with a high nutritional value, such as unsaturated fatty acids (omega-3, omega-6, EPA, and DHA), antioxidants (carotenoids and phenolic compounds), and vitamins. Therefore, the present narrative review aims to compile and critically evaluate the methods used to extract oil from the pulp and almonds of pequi and describes the carotenoid separation from the oil because carotenoids are natural pigments of great interest in the pharmaceutical and food industries. It is emphasized that the main challenges linked to bioactive compound extraction are their susceptibility to degradation in the processing and storage stages of pequi and its derived products.
