Efficient and eco-friendly extraction of corn germ oil using aqueous
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.
Usually the corn germ is around 8% in the total corn grain, and the corn germ’s oil content is approx. 50%. There are two common production methods for corn germ oil: pressing method, suitable for small and medium-sized corn oil producers, and solvent extraction method, suitable for large-scale corn oil producers.
Bioactive Phytochemicals from Corn (Zea mays) Germ Oil Processing By
In general, it is verified that corn oil processing by-product has a dry matter content of 89.0%, crude protein around 10.6%, the crude fiber of 4.6%, ether extract close to 1.34%, in addition to calcium, phosphorus, several amino acids such as methionine, lysine, and tryptophan [ 22, 23, 24 ].
3. Corn Husks. Corn husks are the most abundant and least valuable by-product of corn industrial processing, accounting for 10% to 14% of the total fiber content of corn [ 47 ]. Corn husks contain 382 g cellulose, 445 g hemicellulose, 66 g lignin, 19 g protein, and 28 g ash per kg of dry matter [ 48 ].
Biodiesel production from corn oil: A review
Corn with an oil content level above 6% is designated 'high oil corn'. The corn germ is the most important part of the kernel for oil production. Corn germ contains 35–56% oil, linoleic acid being the most common fatty acid (49–61.9%) [23]. In addition, corn germ contains about 1–3% phosphatides, 1% sterols, and 1.5% FFAs.
Oil content of Corn / Maize germ produced by Wet Milling is as high as 50% and that by Dry Milling is about 25%. 2 Stage pressing is required for wet milled corn germ and single stage pressing is required for dry milled corn germ. About 8 – 10 % residual oil is left in the corn meal which is an excellent source of Animal Feed.
A More Efficient Solution For Processing Corn Germ
Designed for difficult-to-process materials like corn germ, palm kernel, and grapeseed, the Duo’s unique dual-pressing action can reduce residual oils to 5-6% in a single pass. Models of this machine from the 1930s are still operating today, earning the Duo a reputation as the most durable, long-lasting press in the oilseed extraction industry.
The aim of this work was to investigate corn germ oil extraction using supercritical CO2 and cosolvents addition (hexane, acetone and ethanol). The effects of temperature (45–85 °C) and pressure (15–25 MPa) on the extract yield were evaluated for the tests conducted only with supercritical CO2. The addition of cosolvents to supercritical CO2 was also examined at 25 MPa and 60 °C. The
Development and Utilization of Corn Processing by-Products: A Review
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
Besides cornstarch and corn oil as the main products of wet milling process, the process generates multiple coproducts of corn gluten feed, corn gluten meal, corn germ meal, and CSL. One bushel of corn (56 pounds) processed by a wet mill generates approximately 12.9 pounds of corn gluten feed, 3.1 pounds of corn gluten meal, and 0.5 pounds of corn germ meal ( Hoffman, 2011 ).
