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.
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 dioxide (Sc-CO 2) and Soxhlet with hexane and ethanol.

It contains 31–35% crude fat (dry basis, db) and is the primary source for the production of edible corn oil. Corn germ also contains 18–22% (db) crude protein, which accounts for about 29% of the total protein in whole corn . Of these proteins, more than 60% are the water-soluble albumins and saline-soluble globulins [2, 3].
PRODUCTION OF COOKING OIL FROM CORN GERM USING SUPERCRITICAL
Batch extraction was used throughout the experiments. In this study, corn germ oil was extracted using SC-CO2at temp of 25 to 60 °C, with pressure of 150 to 300 bar. The flow rate of CO2 was fixed at 4 L/min in all experiments. Figure 3.1 shows the schematic diagram of SC-CO2extraction system.
The quality of corn germ oil is affected by the method of oil extraction, corn germ quality, etc. The effect of moisture and heat treatment of corn germ on oil quality was studied, results showing that increasing the moisture contents of the corn germ from 8 to 25% before oil extraction increased the acid values (3.02–4.01 mg KOH/g), peroxide
Bioactive Phytochemicals from Corn (Zea mays) Germ Oil
production of corn oil [48].Corn oil, producedbysolvent extraction or pressing, is a type of high-quality vegetable oil containing polyunsaturated fatty acid (PUFA) [49]. Although corn has great industrial potential, its grains are rich in starch and oil [12]. Fatty acids found in corn are found in the germ with a value of approxi-mately 85% [50].
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
Comprehensive utilization of corn starch processing by
Therefore, commercial corn oil is mostly extracted from corn germ and is commonly known as corn germ oil. Corn germ oil is one of the nutritional vegetable oils with a high content of unsaturated fatty acids (≥ 80%), especially linoleic acid (≥ 50%) (Table 4), total trans fatty acid content was
Maize-germ oil is obtained from seedlings from the Zea mays L. (Gramineae) by pressing (cold-pressed maize-germ oil) or by extraction, after which it is refined (refined maize-germ oil). Its main use is in cooking, where its high smoke point makes refined corn oil a valuable frying oil, but it is also a feedstock used for biodiesel.
- What is corn germ oil processing by-products?
- Corn (Zea mays L.) is one of the most relevant and cultivated cereals. During the processing of corn, especially in obtaining edible oil, large quantities of by-products are generated, called corn germ oil processing by-products. In this sense, this chapter provides...
- How to extract oil from corn germ during flour processing?
- 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 dioxide (Sc-CO 2) and Soxhlet with hexane and ethanol.
- Can oil and protein extracts be recovered from corn germ?
- Oil and proteins were successfully recovered from corn germ by a biorefinery scheme. Oil extraction yield and TPC of oils were influenced by the polarity of solvents. The protein content of recovered extracts ranged from 20 to 48%. The functionality of protein extracts depended on the defatting pretreatment.
- Is corn germ oil edible?
- Corn germ oil was confirmed to be one of the edible oils by WHO (World Health Organization) and FAO (Food and Agriculture Organization of the United Nations) due to its superior oxidative stability and nutritive properties. Table 4. Fat acid composition in corn germ and bran. Table 5.
