• How to extract corn germ oil in semi-batch process?
  • The extraction of corn germ oil was evaluated using pressurized propane as solvent in semi-batch process as an alternative approach to organic solvent extraction. The effect of temperature (20, 40, 60 ¡ãC), pressure (20, 60, 100 bar), particle size and confinement time were studied.
  • How to extract oil from corn or maize germ?
  • The main methods to extract oil from corn or maize germ: Screw pressing and solvent extraction . “Screw Oil Pressing / Expelling” is the most used in small to medium scale corn oil manufacturing process. (At present, most corn oil companies or factories use screw pressing process, the oil yield is around 70%.)

  • What is the extraction yield of corn germ oil?
  • The highest extraction yield with propane was 38.4?¡À?1.2 wt% at 20 ¡ãC, 20 bar, 30 min and 0.95 mm particle size. Corn germ oil is widely used for culinary preparation because of its pleasant and slightly sweet taste.
  • What is the oil production process of maize germ?
  • The oil production process of maize germ is similar to that of rice bran. Also must pay attention to reasonable storage, embryo processing, oil extraction and dewaxing of crude oil. The global corn oil market is unique in several ways. Corn oil is relatively cheaper than majority of other variety of vegetable oils.
  • Can hexane extract be used to extract corn germ oil?
  • Extraction with subcritical propane resulted in corn germ oils with properties similar to those obtained in classic extraction procedures using hexane. However, both propane and hexane extracts had lower total phenolic content and antioxidant activity compared with Soxhlet extraction with ethanol or ethyl acetate.
