Coprocessing Corn Germ Meal for Oil Recovery and Ethanol
Efforts to engineer high-productivity crops to accumulate oils in their vegetative tissue present the possibility of expanding biodiesel production. However,
Coprocessing Corn Germ Meal for Oil Recovery and Ethanol
Corn germ meal was pretreated. Pretreated hydrolysate or solids were fermented for 96 h to produce ethanol. After distillation, lipids were extracted from spent fermentation whole broth or solids. The severity parameter R o is defined by Equation (1) [ 18, 30, 31, 32 ].
Corn germ oil extraction with compressed propane compared
The corn germ samples used in this study had a real particle density of 1100 kg/m3 and a moisture content of 6.00 ± 0.02 wt%. In this regard, Christianson et al. (1984) demonstrated that corn germ moisture contents below 8% have a minor influence in the extraction process. Table 1 shows the apparent bed density and bed porosity of the three differe...ScienceDirect
(PDF) Recoveries of Oil and Hydrolyzed Sugars from Corn Germ
Corn germ meal was chosen as a model feedstock representing lipid-producing energy crops. Germ meal was pretreated at 160 and 180 C for 10 and 15 min at 20% w/wsolids loading. Enzymatic...
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)
Fermentation of NaHCO3-treated corn germ meal by Bacillus
Abstract Sodium bicarbonate pretreatment and solid-state fermentation (SSF) were used to maximize the nutritional value of corn germ meal (CGM) by inoculating it with Bacillus velezensis CL-4 (isolated from chicken cecal contents and capable of degrading lignocellulose). Based on genome sequencing, B. velezensis CL-4 has a 4,063,558 bp ring chromosome and 46.27% GC content. Furthermore, genes

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 Germ - an overview | ScienceDirect Topics
The dried germ contains about 50% oil, in which the oil constitutes about 85% of the total amount of oil present in the corn. The oil is produced by first expelling the germ and then extracting the expeller cake with n -hexane. Global annual corn production is 700 million tonnes but corn oil production is only 400 000 tonnes.
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
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. Moreover, the extraction kinetics for the pressurized solvent were determined. Temperature and pressure had no
