• 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 to increase oil yield from corn germs?
  • The oil yield from corn germs depends on factors such as the type of pre-heating, moisture content, temperature, screw speed, and nozzle diameter. To increase the oil yield, heating the corn germs in a conventional (at 180?¡ãC) or microwave (at 1500?W and 2450?MHz) oven can be carried out.
  • What is the oil yield from Steam exploded corn germ?
  • Under the extraction conditions applied for the untreated germ, the oil yield from the steam-exploded corn germ increased to 88.51%. Corn germ soaking with citric acid (0.05?M) for 2?h at a solid-to-liquid ratio of 1:2 (w/v), followed by steam explosion results in an oil yield of 93.74%.
  • What is corn oil yield?
  • Corn oil yield is about 172?L/ha . The moisture at harvest and drying temperature are the most influential factors affecting the germ oil content and oil yield . Generally, the germ weight and oil yield decrease as the kernel moisture at harvest and the temperature of the drying air increase.
  • What is high oil corn?
  • Corn with an oil content level above 6% is designated ‘high oil corn’. The corn germ is the most important part of the kernel for oil production. Corn germ contains 35¨C56% oil, linoleic acid being the most common fatty acid (49¨C61.9%) . In addition, corn germ contains about 1¨C3% phosphatides, 1% sterols, and 1.5% FFAs.
  • What happens if you press corn germ in expeller? presses?
  • The pressing of wet process corn germ in Expeller? Presses can produce, within the barrels of the machines, sufficiently high degrees of temperature to cause charring of the cake and excessive coloring of the product oil.
