• 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.
  • 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.
  • 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.
  • 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. The content of linoleic acid is as high as 56%.
  • Can oil and protein extracts be recovered from corn germ?
  • Oil and proteins were successfully recovered from corn germ by a biorefinery scheme. Oil extraction yield and TPC of oils were influenced by the polarity of solvents. The protein content of recovered extracts ranged from 20 to 48%. The functionality of protein extracts depended on the defatting pretreatment.
  • Does Tempering degerming reduce endosperm fractions in corn germ-bran mixture?
  • The tempering-degerming process implemented to achieve the corn germ-bran mixture may let more endosperm fractions attached to the germ than the dry mechanical degerming and bran separation implemented by Castelmais. 3.2. Oil recovery and characterization Table 1 summarizes data of yields and oil composition for the different extraction methods.
