• 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.
  • 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%.
  • What is corn germ oil processing by-products?
  • Corn (Zea mays L.) is one of the most relevant and cultivated cereals. During the processing of corn, especially in obtaining edible oil, large quantities of by-products are generated, called corn germ oil processing by-products. In this sense, this chapter provides…
  • 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).
  • 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.
  • Which extraction method has the highest yield in corn germs?
  • In both corn germs, the UAE extracts showed the highest yields (about 12%), followed by the extracts obtained by alkaline hydrolysis + sonication (about 5%) and by alkaline hydrolysis (about 3%). Enzymatic hydrolysis was the extraction method with lower yields (less than 1%) in both corn germs.
