• How to extract oil from corn germ during flour processing?
  • This work aimed the recovery of oil and protein fractions from corn germ (CG) generated as a by-product during flour processing. Several oil extraction techniques were investigated: hexane at room temperature, hexane at 45 ¡ãC, supercritical carbon dioxide (Sc-CO 2) and Soxhlet with hexane and ethanol.
  • How is corn germ extracted from starch?
  • During the wet milling process, the germ is isolated from the starch using cyclone separators, washed, and dried. The dried germ contains about 50% oil, in which the oil constitutes about 85% of the total amount of oil present in the corn. The oil is produced by first expelling the germ and then extracting the expeller cake with n -hexane.
  • 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.
  • How is corn bran oil extracted?
  • In addition to traditional solvent extraction (petroleum ether), the methods of hexane extraction and subcritical butane extraction were used to extract corn bran oil which contains high content of unsaturated fatty acids and phytosterols [ 144 ].
  • What is a corn germ extractor?
  • Corn germ is a part of the corn embryo, which is located below the corn kernel and is mainly involved in the growth and development of corn (Different Strategies to Obtain Corn (Zea mays L.) Germ Extracts with Enhanced Antioxidant Properties, Design of corn germ extractor based on S7-1200 PLC).
