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 techniques were investigated: hexane at room temperature, hexane at 45 °C, supercritical carbon
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.
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
Corn Germ - an overview | ScienceDirect Topics
Corn germ oil ( Zea mays) Corn germ oil is a by-product of the corn oil milling process. Most corn that is harvested is used as feed but the proportion of the corn that is milled is increasing because of bioethanol production. During the wet milling process, the germ is isolated from the starch using cyclone separators, washed, and dried.
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
Introduction. Corn germ is a substantial byproduct of the wet milling and alcohol industry of corn. Corn germ (dry) contains 35?6 % oil, with linoleic acid (C18:2) being the predominant fatty acid (49?1.9 %) and the highest level of tocopherol and phytosterol amongst all vegetable oils, which is a cost-effective resource for healthy nutritious oil.
Kinetic, thermodynamic and optimization study of the
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
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.
Coprocessing Corn Germ Meal for Oil Recovery and Ethanol
Due to the insufficient availability of engineered oil-bearing crop samples, corn germ meal, with 2.3% oil on a dry basis [], was used as a model lignocellulosic
Corn Processing - Crown Iron Works
Corn germ is processed with the Model III Extractor. Desolventizing Once the oil has been removed by the solvent, the solvent must be removed from both the flakes and the corn oil. For the flakes, heat and steam are used to strip and recover the residual solvent. For the corn oil, a distillation system is used to recover the solvent.
