Methods used for extraction of maize ( Zea mays L.) germ oil – a review The composition of corn oil obtained by the alcohol extraction of ground corn Sequential extraction processing of flaked whole corn: alternative corn fractional technology for ethanol production Corn oil production process.
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 to extract oil from corn germ?
Various organic solvents and water have been used for the extraction of corn germ oil. The most common commercial process for obtaining oil from corn germ is extraction by n -hexane because of its high extraction efficiency and low process cost.
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 °C) or microwave (at 1500 W and 2450 MHz) oven can be carried out.
