Efficient and eco-friendly extraction of corn germ oil using
Introduction. Corn germ is a substantial byproduct of the wet milling and alcohol industry of corn. Corn germ (dry) contains 35–56 % oil, with linoleic acid (C18:2) being the predominant fatty acid (49–61.9 %) and the highest level of tocopherol and phytosterol amongst all vegetable oils, which is a cost-effective resource for healthy nutritious oil.
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 ].
Oil and protein recovery from corn germ: Extraction yield
The residual oil content in corn meal after Sc-CO 2 extraction could have affected protein extraction, leading to a slightly lower yield (21.3%) than that from hexane defatted meal at the same temperature. However, no significant difference was observed in the recovery yields between Hexane at RT and undefatted meals (19.0% and 19.9%
5.1. Corn Germ Oil. Corn germ oil is a nutritious and healthy edible oil. It has a transparent golden yellow color and a fragrant fragrance. It is called “liquid gold” by Western countries. Corn germ oil contains 80–85% of unsaturated fatty acids, oleic acid, linoleic acid, and α-linolenic acid. The content of linoleic acid is as high as
Front‐end corn germ separation: Process variations
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
The extraction of corn germ oil was evaluated using pressurized propane as solvent in semi-batch process as an alternative approach to organic solvent extraction. The effect of temperature (20, 40, 60 °C), pressure (20, 60, 100 bar), particle size and confinement time were studied. Moreover, the extraction kinetics for the pressurized solvent were determined. Temperature and pressure had no

By using oven-dried corn germ samples (6 g) from a commercial corn wet mill, corn oil yields of about 80% were achieved using three different commercial cellulases. A fourfold scale-up of the method (to 24 g of germ) resulted in oil yields of about 90%. Nine other commercial enzymes were evaluated and resulted in significant but lower oil yields.
Kinetic, thermodynamic and optimization study of the corn
Before oil extraction, the corn germ was ground by a domestic grinder (Braun, Germany) for 2 min. The CGO content of the corn germ determined by the Soxhlet extraction using n-hexane (HPLC grade; Lab–Scan, Ireland) at the SGR of 3:1 mL/g for 3 h was 45.35 ± 0.32 g/100 g dried germ. 2.2. Extraction of corn germ oil2.2.1. Maceration of corn germ
An improved aqueous extraction method has been established for extraction of oil from corn germs and the quality of extracted oil was superior to commercial oils. 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
