“…Alcoholic solvents presented accumulated extraction yields higher than 90%, however, IPA0 presents better performance (96.3 ± 0.1%) when compared to Et0 (92 ± 1%) ( p < 0.05). Previous studies comparing the performance of Et0 and IPA0 have shown that with the latter is achieved higher oil extraction yields, which may be related to the lower polarity of IPA0.…”

The aim of this study is to evaluate the performance of ethanol and isopropanol in the extraction of macadamia oil and the production of protein concentrates from the defatted meal. Partially defatted macadamia cake is submitted to batch extractions in one stage of contact at 60, 75, and 90 °C, while the sequential extraction trials considering four stages are performed at 75 °C. Oil extraction yield is influenced by the solvent type, temperature, and pre‐treatment of the material. Absolute isopropanol at 90 °C enables to extract 66% of the oil while in the sequential configuration, oil yield up to 96% is attained after four stages. The retention of the solution adhered to the fiber (liquid holdup, LH) is affected by the type of solvent and characteristics of the raw material, being obtained LH values higher than 2. The oil extraction conditions affect negatively on the nitrogen solubility index of the defatted meal. The solvents in absolute degree impact less on the solubility of the proteins, enabling the production of macadamia protein concentrates (protein content of 70%) with functional properties suitable for using in the food industry. Practical Applications: This study is useful to oilseed processors and researchers because it addresses the issue of using macadamia cake as raw material to oil extraction with alcoholic solvents, ethanol, and isopropanol, which are less flammable and toxic than hexane. In addition, it is evaluated the effect of process variables on the oil yield, liquid holdup, and characteristics of the extraction products (oil and defatted meal). The results of this work could help to develop macadamia oil extraction process safe for the workers of oil industry and consumers and, simultaneously, to enable the use of by‐products (defatted meal) in the protein concentrates production. Macadamia oil extraction, from partially defatted macadamia cake, is carried out using ethanol and isopropanol (absolute and hydrated) as solvents. The products of macadamia oil extraction are characterized, thus the extracted oils show typical fatty acid composition and the defatted meal presented higher protein content than raw material. Therefore, from these defatted meals are produced macadamia protein concentrates, which show good functional properties to be used as food ingredients.

“…The same did not happen in mass yield and, or deacidification yield, because, as shown in Figures 3 and 4, the results of yield do not comply the number of contacts. This demonstrates that the solvent has more affinity with fatty acids, and the losses in the process refer to the neutral oil drag (Sawada, Venâncio, Toda, & Rodrigues, 2014; Scharlack et al, 2017; Toda, Sawada, & Rodrigues, 2016).…”

“…Some works suggest to replace it with green solvents such as ethanol and isopropanol, or such as mechanical extraction without solvent (Araújo et al, 2018; Bessa, Ferreira, Rodrigues, Batista, & Meirelles, 2017; Cornelio‐Santiago, Mazalli, Rodrigues, & Oliveira, 2019). Furthermore, modern methods such as aqueous, enzymatic extraction with microwaves, ultrasound, or supercritical fluids can be used (Gaber, Tujillo, Mansour, & Juliano, 2018; Koubaa, Mhemdi, & Vorobiev, 2016; Scharlack, Aracava, & Rodrigues, 2017), increasing the extraction yield and maintaining oil quality (Sánchez, Fernández, & Nolasco, 2017).…”

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.
