Summary: Rapeseed oil is the third most consumed culinary oil in the world, known for its high content of unsaturated fatty acids. Recent studies have identified nine functional components in rapeseed oil that contribute to its health benefits, including vitamin E, flavonoids, squalene, carotenoids, glucoraphanin, indole-3-Carbinol, sterols, phospholipids, and ferulic acid. This review highlights the potential of rapeseed oil for the development of functional foods.

Summary: Deep eutectic solvents (DESs) have been recognized as eco-friendly alternatives to conventional solvents. However, reliable methods for selecting task-specific DESs are limited. Using COSMO-RS, 126 DESs were screened based on their solubility capacity to estimate their potential use as plant seed oil extractants. The results showed that DESs with higher linoleic acid solubility had lower solubility for protein, and the similarity of DESs to both linoleic acid and protein was compared through sigma-profiles. DESs with high linoleic acid solubility could be used as individual solvents, while DESs with high protein solubility could be used as co-solvents with organic solvents.

Summary: In this study, Span 80 was used to enhance the solvent extraction process and its mechanism was explored. The results indicated that different solvents had different effects on oil recovery, with toluene showing the highest recovery and n-heptane showing the lowest. Complex solvents improved oil recovery and decreased viscosity. The C/H ratio was correlated with oil recovery, with an increase in asphaltene and resin content leading to a higher C/H ratio. Span 80 increased the C/H ratio, reduced viscosity, and minimized solvent loss.

Summary: This study investigated the effects of different pretreatment and processing methods on the physicochemical properties, antioxidant substances, and antioxidant capacity of high-oleic rapeseed oil (HORO). The results showed that the microwave pretreatment-hexane extraction (M-HE) method resulted in higher levels of tocopherols, polyphenols, and phytosterols in HORO, indicating stronger free radical scavenging capacity. M-HE is a promising method for producing HORO with higher stability and nutritional value.

Summary: This study investigated the effects of downstream processing steps, lipid removal techniques, and extraction pH on the properties of proteins extracted from rapeseed cake. The pH 4 and pH 8 protein extracts showed differences in physical functionality tests, with pH 4 extracts having higher foaming capacity and stability but lower emulsion stability compared to pH 8 extracts. Overall, the lipid removal technique used did not significantly impact the properties of the extracted proteins.

Summary: This study compared the lipid composition and active constituents of Trichosanthes kirilowii Maxim seed kernel and shell oil using four different extraction techniques. The results showed that ultrasonic-assisted solvent extraction had the highest lipid yield, while supercritical fluid extraction had the lowest. The extraction method and shells significantly affected beneficial phytochemicals and antioxidant activity. The information provided in this study is valuable for manufacturers in selecting the appropriate method to produce Trichosanthes kirilowii Maxim seed oil with desired quality attributes and chemical compositions for the target end-user.

Summary: Petrochemical, coal chemical, and metal smelting industries produce oily wastewater with surfactant-stabilized oil microdroplets, which are difficult to treat. This study analyzes the mechanism and factors affecting the extraction efficiency of surfactant-stabilized oil microdroplets using solvent extraction. The results show that the extraction is accomplished by the mass transfer of extractant from the exterior to the interior of the oil microdroplets and the rise of extractant-containing oil droplets in the aqueous phase. Multistage extraction experiments demonstrate that this solvent extraction technology can treat oily wastewater to discharge standards. Non-polar extractants are considered more suitable due to their regenerability, lower regeneration costs, and better extraction performance.

Summary: This study investigated the extraction and upgrading of asphaltenes under methane environment using typical paraffinic and aromatic oil components as solvents. It was found that solvents help reduce coke formation, increase light product yields, and prevent excessive polymerization of asphaltenes. Paraffinic solvents led to higher light fraction yields, while aromatic solvents exhibited a noticeable solvent effect in improving asphaltene dispersion.

Summary: This study characterized Wei safflower seed oil (WSO) prepared by the cold pressing method and organic solvent extraction method. Cold-pressed WSO (CP-WSO) had a lower yield compared to n-hexane-extracted WSO (HE-WSO). The physicochemical properties and fatty acid compositions were similar in both types of oil, with high levels of linoleic acid. However, CP-WSO had better color and lower solvent residue. The vitamin E content and type in CP-WSO were also superior, contributing to its high oxidative stability in the Rancimat test. These findings provide valuable insights for the development of Wei safflower seed oil.

Summary: This study conducted a quantitative analysis to predict the yields of deasphalted oil (DAO) in the solvent deasphalting (SDA) process. The effects of temperature and solvent-to-oil ratio (SOR) on the DAO yield were explained using simple and accurate correlations. The results showed that temperature and SOR have a significant impact on the DAO yield.
