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 °C, supercritical carbon dioxide (Sc-CO 2) and Soxhlet with hexane and ethanol.
What is corn oil extraction machine?
The corn oil extraction machine, also known as screw oil press machine, is used for the mechanical pressing of corn germ oil. The corn germ oil press machine adopts directional pressure bearing and multi-stage propulsion to realize high oil yield.
What are the features of corn germ oil press machine?
The corn germ oil press machine adopts directional pressure bearing and multi-stage propulsion to realize high oil yield. Scientific heating, automatic control of pressing temperature, high quality of pressed corn oil are among the outstanding features.
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.
