UFDCEffects of Extraction and Refining on the Quality
Linoleic acid accounted for 72-79% total fatty acid in all oils. Concentrations of tocopherols and tocotrienols in muscadine seed oil ranged from 11.8 to 53.8 mg/100 g and 25.3 to 44.3 mg/100 g,

Variations in Physico-Chemical and Antioxidant
For example, Soxhlet extraction method, based on solid-liquid extraction, gives higher oil yield when compared to supercritical CO2 extraction (Da Porto et al. 2012) and cold pressing (Ixtaina et al.
Compared with traditional extraction methods, these novel methods have the advantages of a higher oil extraction rate, less extraction time and less solvent consumption. In
- How is muscadine pomace extracted?
- Muscadine pomace from purple Noble grapes and bronze Carlos grapes are dried and seeds are separated. Seed oils are extracted using a Soxhlet extractor by hexane, mechanical pressing, or enzyme‐assisted aqueous extraction. Oil extraction efficiencies are assessed using yield by dry weight.
- Does muscadine grape seed oil remove fatty acids?
- Refining the oil removes peroxides and free fatty acids without altering fatty acid composition but eliminates 44–100 and 11–95% of tocopherols and tocotrienols, respectively. Practical Applications: Muscadine grape seed oil is high in linoleic acid and antioxidant components, making it an ideal product for culinary, and cosmetic purposes.
- Which solvent is used to extract grape seed oil?
- The extraction of grape seed oil (GSO) for food and cosmetic applications was performed with 2-methyloxolane (2-MeOx) as a green solvent. The oil extraction yield, the tocopherol and tocotrienol content, the fatty acid and polyphenol profiles of the oils were analysed and compared with hexane.
- What is muscadine grape seed oil used for?
- Practical Applications: Muscadine grape seed oil is high in linoleic acid and antioxidant components, making it an ideal product for culinary, and cosmetic purposes. The unrefined oil is high in tocopherol and tocotrienol, shown to have anti‐adipogenic and anti‐inflammatory capabilities.
- What is the difference between oil extraction and hexane extraction?
- For seeds with relatively high oil content (above 20 %), industrial extraction typically involves both pre-pressing and solvent extraction using hexane. In contrast, seeds with lower oil content, like GSs, are usually extracted directly with hexane (Uitterhaegen and Evon, 2017).
- What is the best method for separating oil?
- Currently, solvent extraction with hexane is the most popular method for separating oil due to its high efficiency (residual oil content < 2 %) and ability to process large volumes (Pérez et al., 2019). After solvent extraction, the oil is usually refined to remove unpleasant compounds.
