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.
Can a high-shear extrusion system extract oil from corn germ?
As technologies continue to advance, high-shear extrusion systems may offer a more efficient alternative for extracting oil from wet processed corn germ. Extrusion systems like the Anderson Dox Extruder eliminate the need for separate steam heating and drying steps required in traditional stack cooking vessels.
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.
How to extract corn oil?
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.
