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) and percentages of α-linolenic acid (C18:3) lower than 1.5%. Therefore, it cannot be
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
Efficient and eco-friendly extraction of corn germ oil using
Oil extraction 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).
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
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
Biodiesel production from corn oil: A review ScienceDirect
This paper provides a general overview of the usage of corn oil as oily feedstock for biodiesel production. First, corn cultivation, corn germ composition,
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
Materials Dry corn germ was purchased from , Shandong Province, China. The raw material (dry corn germ) contained 6–7 % (w/w,
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
