Efficient and eco-friendly extraction of corn germ oil using aqueous ethanol solution assisted by steam explosion, Journal of Food Science
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
The corn wet milling process separates corn into its four basic components: starch, germ, fiber, and protein. There are five basic steps to accomplish this process. First the incoming corn is inspected and cleaned. Then it is steeped for 30 to 40 hours to begin breaking the starch and. protein bonds. The next step in the process involves a
Oil and protein recovery from corn germ: Extraction yield, composition and protein functionality
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.
Neutral oil losses, for crude corn oils with free fatty acid contents between 8% and 14%, may reach 15%–25% during chemical refining; thus justifying the preferential use of physical refining (Hamm and Hamilton, 2000; Dorsa, 2004; Dijkstra and Segers, 2007).
Formation, characterization, and potential food application of rice bran wax oleogels: Expeller-pressed corn germ oil versus refined corn oil
To visualize the formation of oleogel, all the samples were placed upside down and were considered as oleogel if no oil flows down. As can be seen from the inserted picture in Fig. 1 B, all the samples successfully formed oleogels denoting that both refined corn oil and EP corn germ oil have the capability to form oleogel by RBX at a concentration of ≥ 3%.

Pretreatment of corn oil for physical refining
pretreatment with phosphoric or citric acid and 1 to 3% of ac-. tivated earth (18). In physical refining of corn oil by the Simon Rosendows. System Ltd. process, 0.15% of phosphoric acid at 60
Color reversion has long been a major problem for the vegetable oil industry, and the enzymatic oxidation of γ-tocopherol is thought to trigger this phenomenon. In this study, first, the extraction, purification, and detailed characterization of tocopherol oxidase from fresh corn germs were performed. Then, the relationship between the enzyme reaction of γ-tocopherol and oil color reversion
A More Efficient Solution For Processing Corn Germ
Traditional corn germ processing Whole corn kernels only contain a small amount of fat, around 5% by weight. But the germ that remains after the starch is removed through wet processing can contain up to 50% oil by weight. This produces a high-quality cooking oil—one of the most expensive in the oilseed market, thanks in part to its high smoke point, neutral flavor, and free fatty acid content.
Deoxynivalenol (DON) contamination in germs and germ oil is posing a serious threat to food and feed security. However, the transformation pathway, the distribution of DON, and its degradation products in edible oil refining have not yet been reported in detail. In this work, we systematically explored the variation of DON in maize germ oil during refining and demonstrated that the DON in germ
