Oil and protein recovery from corn germ: Extraction yield
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
Corn germ oil extraction with compressed propane compared
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.
Corn Oil: Composition, Processing, and Utilization
Corn oil is an excellent source of essential fatty acids, which typically exceed 60% of its total composition, with the main contribution of linoleic acid (C18:2)
Efficient and eco-friendly extraction of corn germ oil using
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
Extraction of corn germ oil with supercritical CO2 and cosolvents
the supercritical extraction of corn germ oil at pressures of 34–55 MPa and constant temperature of 50 C. Experi-mental assays resulted in higher quality oil with a maxi-mum
Efficient and eco-friendly extraction of corn germ oil using
Corn germ oil was extracted from milled corn germ using diluted aqueous ethanol as solvent. Batch extractions were carried out in 500 mL glass reactor vessels which were series connected with a constant temperature water bath machine (MP-501 A, Shanghai Yiheng Scientific Instrument Co., Ltd., China).
Efficient and eco-friendly extraction of corn germ oil using
A process for the aqueous enzymatic extraction of corn oil from dry milled corn germ and enzymatic wet milled corn germ (E-Germ) J Am Oil Chem Soc. 2009; 86:469–474. doi:
Corn Oil: Composition, Processing, and Utilization
Most of the commercial corn oil is extracted from the germ and this is commonly known as 渃orn germ oil.?The germ from wet-milling operations (see Chapter 18) is recovered with up to 50% oil, which must be quickly processed because of its low microbiological and chemical stability.
Oil separation from wet-milled corn germ dispersions
Another approach is to extract corn germ by aqueous extraction (AE) or aqueous enzymatic extraction (AEE) with less costly equipment. AE ( Rhee et al., 1972,
Cold pressed corn (Zea mays) oil - ScienceDirect
During the dry or wet milling process, corn germ as oil source is separated from the kernel for starch production. A wet milling process is usually preferred for corn germ separation to extract the oil. Corn oil is usually extracted with expeller pressing together with hexane or isohexane extraction to achieve around 97%?9% yield.
