Oil and protein recovery from corn germ: Extraction yield, composition and protein functionality
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.
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
Bioactive Phytochemicals from Corn (Zea mays) Germ Oil Processing By-products
In general, it is verified that corn oil processing by-product has a dry matter content of 89.0%, crude protein around 10.6%, the crude fiber of 4.6%, ether extract close to 1.34%, in addition to calcium, phosphorus, several amino acids such as methionine, lysine, and tryptophan [ 22, 23, 24 ].
Corn oil, being the most valuable corn component, presents itself as an attractive candidate for front-end and tail-end separation of germs. Although the corn oil does not take part in starch fermentation into ethanol, the implication of the front-end degermination in dry-grind corn process on downstream product recovery is an essential consideration in bioethanol yield.

Corn germ meal, the solid residue of corn germ after oil extraction from wet-milled corn, is a low-value product rationed in ruminant animal diets [21,22]. Liquid hot water (LHW) pretreatment, an essential step to enhance the enzymatic recovery of fermentable sugars, solubilizes hemicellulose and partially removes lignin.
Development and Utilization of Corn Processing by-Products: A Review, PMC, National Center for Biotechnology Information
As an important food crop, corn has an important impact on people’s lives. The processing of corn produces many by-products, such as corn gluten meal, corn husk, and corn steep liquor, which are rich in protein, oil, carbohydrates, and other nutrients, all of which are inexpensive. Their accumulation in large quantities during the production
The oil is predominantly located in the germ (about 80–84% of total kernel oil) (Rajendran et al., 2012), which can be separated from corn kernels by degerming processes. Although the corn oil is commonly obtained from the germ, it can also be recovered from whole kernels and by-product streams in ethanol production ( Zabed et al., 2017 ).

Smuda et al. [25] analyzed the effects of using four different solvents in the extraction of corn by-products; in relation to the germ meal, it can be said that the order of TPC extraction was: acetone distilled water methanol ethanol, in a. 1 < < range of values from 638 to 1356 mg GAE 100 g DW (Table 3).
