“…Furthermore, Go et al [ 21 ] found that, regardless of conditions, 90% of the extractable lipids were solubilized in hexane in less than 10 min. Similarly, the study of Azevedo et al [ 23 ] also revealed that the oil extraction was sufficiently completed in 30 min, with the full extraction taking 0–90 min. Because oil extraction is essentially a process of dynamic mass transfer [ 11 , 24 ], a short extraction time makes it difficult for the solvent to fully come into contact with the oil and form a mass transfer balance, thus resulting in incomplete extraction and a low oil yield [ 25 ].…”

In order to improve the extraction ratio of rice bran oil, a single-factor experiment and response surface methodology with a central composite design were used to determine a new mixed solvent and the optimal extraction conditions of the mixed solvent. The effects of solid–liquid ratio, extraction time, extraction temperature, and oscillation speed on the extraction ratio were investigated. The regression equation was established, and the optimal extraction conditions were determined as follows: a solid–liquid ratio of 5.5:1, extraction temperature of 45 °C, extraction time of 12 min, and extraction ratio of rice bran oil of 85.8%. Compared with traditional solvent extraction, the peroxide value, acid value, iodine value, and fatty acid composition content of rice bran oil extracted using the new mixed solvent were close to those of n-hexane and significantly lower than those of solvent No. 6, while the content of oryzanol and total sterol increased to 2.7% and 5.1%. This study can be useful in exploring the possibility of new mixed solvents and provide theoretical guidance and data support for the production practice of new mixed solvents.

“…After the solvent reaches its boiling point, the steam rises and is condensed into a liquid that circulates and drips into the extractor [36]. After a period of time, when the liquid level exceeds the highest point of the siphon, the solution flows back into the flask.…”

“…During the extraction process, the influence of the solvent immersion area on the extraction process is significant, so before extraction, the substance to be tested should be finely ground to increase the contact area [35]. After the solvent reaches its boiling point, the steam rises and is condensed into a liquid that circulates and drips into the extractor [36]. After a period of time, when the liquid level exceeds the highest point of the siphon, the solution flows back into the flask.…”

Deep eutectic solvents (DESs), as a new type of eco‐friendly solvent, have attracted increasing attention on the extraction and separation of flavonoid compounds from various samples, owing to their excellent properties such as biodegradability and ease of handling with very low toxicity. This article provides a status review of the applications of DESs in the extraction of flavonoids, including the introduction of flavonoid compounds, the properties and superiority of DESs, and extraction methods (ultrasonic‐assisted extraction, heating reflux extraction, matrix solid‐phase dispersion, and solid‐phase extraction). Finally, prospects and challenges in the application of DESs on extraction and separation are extensively elucidated and critically reviewed.

“…This enabled a corn oil recovery of 90.2% in short confinement time (10 min). [ 28 ] Solvent mixtures can often be used to extract edible corn oil because they can provide better extraction efficiency than using a single solvent. For instance, the mixture of 30% hexane and 70% ethanol improved corn oil quality but resulted in higher loss during refining compared to hexane extraction.…”

Corn oil is a major agricultural commodity, and it is a staple in kitchens worldwide. This comprehensive review aims to provide a holistic understanding of corn oil processing, composition, nutritional benefits, properties, and market dynamics. The processing of corn oil poses challenges in achieving optimal extraction efficiency while addressing environmental concerns. Currently, hexane‐extracted corn oil dominates the market, with cold‐pressed corn oil being a niche product. Ongoing efforts within the industry focus on exploring alternative, environmentally friendly extraction methods such as critical CO2 and enzymatic‐assisted extraction. Corn oil is recognized for its rich composition in monounsaturated and polyunsaturated fats, tocopherol content, and potential antioxidant benefits. However, its high omega‐6 fatty acid content, while contributing to its stability, has raised discussions about its potential impact on inflammatory responses when consumed excessively. Due to its high smoke point, corn oil is suitable for high‐temperature cooking without compromising its neutral taste. Yet, its oxidation stability is lower compared to other commercial oils. Relying on oleic‐rich varieties or incorporating antioxidants could help enhance its stability and mitigate potential oxidative concerns. In the future, advancements in processing technologies promise to elevate the nutritional profile of corn oil, aligning it with the evolving preferences of health‐conscious consumers and addressing sustainability concerns.Practical Applications. This review provides crucial insights into the processing, nutritional profile, and market dynamics of corn oil, benefiting researchers and industry professionals. By understanding the challenges and advancements in extraction methods, researchers can develop more sustainable and efficient processes. The detailed analysis of corn oil's composition and functionality provides practical solutions for improving product shelf‐life and quality. This comprehensive review supports the optimization of corn oil production and utilization and aids in positioning corn oil as a competitive and versatile option in the global vegetable oil market.
