• How is corn germ oil extracted?
  • At present, there are many extraction methods for corn germ oil, and the traditional extraction method of corn germ oil is the pressing method. The pressing method is to squeeze the oil out through mechanical pressure, which is a method commonly used in oil factories.
  • Can aqueous ethanol extract corn germ oil?
  • This result proved the preponderance of aqueous ethanol method again. In this study, an efficient and eco-friendly extraction process was developed by the aqueous ethanol extraction with steam explosion pretreatment for obtaining corn germ oil.
  • What is corn germ oil?
  • Corn germ oil is a nutritious and healthy edible oil. It has a transparent golden yellow color and a fragrant fragrance. It is called ¡°liquid gold¡± by Western countries. Corn germ oil contains 80¨C85% of unsaturated fatty acids, oleic acid, linoleic acid, and ¦Á-linolenic acid.
  • What is corn germ?
  • Corn germ is a substantial byproduct of the wet milling and alcohol industry of corn. Corn germ (dry) contains 35¨C56 % oil, with linoleic acid (C18:2) being the predominant fatty acid (49¨C61.9 %) and the highest level of tocopherol and phytosterol amongst all vegetable oils, which is a cost-effective resource for healthy nutritious oil.
  • What fatty acids are in corn germ oil?
  • The main fatty acids in corn germ oil are linoleic (39¨C63%), oleic (20¨C42%), and palmitic (9¨C17%) . According to the same authors, several methods are used for the recovery of corn germ oil, such as pressing, solvent, extraction of aqueous, enzymatic, and supercritical fluid.
  • Can corn germs be milled before oil extraction?
  • Grinding oilseeds prior to oil extraction may enlarge the interface between material particles and aqueous solvent or enzyme, and then enhance free oil yield. In previous research, colloid milling was employed to mill corn germs (Dickey et al. 2010 ). In this study, a dry milling method was developed to grind corn germ.
