First, we need to extract the embryo of corn, remove impurities, and then use a corn oil press machine to complete the extraction of corn oil. The extracted crude corn oil can be refined to obtain edible oil. 1. Corn germ extraction: embryo extraction is one of the important steps for oil extraction.
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 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 germ oil used for?
Corn germ is mainly used as an oil resource to prepare corn germ oil. Corn germ oil is rich in vitamin E and unsaturated fatty acids, such as linoleic acid and oleic acid, which have a protective effect on cardiovascular and cerebrovascular. Do you know how to extract oil from corn with a corn oil extraction machine?
