A Process for the Aqueous Enzymatic Extraction of Corn Oil
reported a solvent-free aqueous enzymatic oil extraction process that achieved oil yields of 80–90% using corn germ from a commercial corn germ wet mill [1, 2]. Since our previous report was published new procedures have been reported for the aqueous enzymatic extraction of oil from soybeans [3, 4] and rapeseed [5, 6]. The newly published procedures
A bench-scale aqueous enzymatic method was developed to extract corn germ oil from corn germ from either a commercial corn germ dry mill or corn germ from a newly-developed experimental enzymatic wet milling process (E-Germ). With both types of germs, no oil was extracted when acidic cellulase was the only enzyme used.
Efficient and eco-friendly extraction of corn germ oil
An improved aqueous extraction method has been established for extraction of oil from corn germs. This method primarily included steam explosion pretreatment and aqueous ethanol extraction. Process variables such as steam pressure, resident time, particle size and ethanol concentration were investigated. The highest yield of 93.74 % was obtained when ground steam-exploded corn germ (1.3 MPa ...

Kinetic, thermodynamic and optimization study of the corn germ
Corn germ oil (CGO) was recovered from the ground corn germ by maceration using n-hexane at the ranges of the temperature and the solvent:germ ratio (SGR) of 20–70 °C and 3:1–10:1 mL/g, respectively.The obtained CGO contained mainly the unsaturated fatty acids (87.09 ± 0.37%) with linoleic and oleic acid as the most abundant while the main saturated fatty acid was palmitic acid.

Not every wet corn germ mill has equipment to process corn germ into oil and meal. These plants market germ to a few extraction plants. The dry brittle germ (3% moisture) may be either hard screw pressed or extracted with prepress solvents (Johnson, 2000a). In hard pressing, as much oil as possible is squeezed out of the germ.
