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.
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 considered a source of omega-3 fatty acids in the diet.
The small production line is easy to operate, with high efficiency of oil extraction and low investment cost, which is suitable for small-scale corn oil producers. If the processing capacity is more than 10 tonnes per day, it can be produced by a complete production line, including three parts: the equipment related to the corn germ treatment
Front‐end corn germ separation: Process variations and effects on
Corn oil, being the most valuable corn component, presents itself as an attractive candidate for front-end and tail-end separation of germs. Although the corn oil does not take part in starch fermentation into ethanol, the implication of the front-end degermination in dry-grind corn process on downstream product recovery is an essential consideration in bioethanol yield.
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.
Impact of Dry-milled Germ Processing on Aqueous Protein machine
The method was developed to address the limitations of the traditional dry milling process and to produce higher purity germ material that would allow cost-effective recovery of protein and oil coproducts (Lohrmann et al. 2008; Wilken and Nikolov 2015).
The TPC values of oils extracted at 45 °C and boiling hexane are consistent with those reported by Shende and Sidhu (2015) for corn oil extracted by hexane (76 mg GAE/kg oil). The highest yield of extraction (37.7 g oil/100 g CG) was obtained by the Soxhlet ethanol method.
Comprehensive utilization of corn starch processing by-products: A
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
2. Optional corn germ extraction line provides equipment with advanced design. 3. Corn oil extraction plant adopts prepressing extraction technology, the crude oil obtained has high quality. 4. Corn oil production line adopts negative evaporation technology, which helps saving energy, improving oil quality and ensuring safe operation. 5.
- How is corn germ oil extracted?
- As a kind of high-quality vegetable oil, corn germ oil has been studied for many years by using lots of extraction methods including pressing extraction, Soxhlet extraction, organic solvent extraction, supercritical CO 2 and aqueous enzymatic [ 124, 125, , , ].
- Does corn germ oil contain linoleic acid?
- Corn germ oil is one of the nutritional vegetable oils with a high content of unsaturated fatty acids (¡Ý 80%), especially linoleic acid (¡Ý 50%) ( Table 4 ), total trans fatty acid content was <0.3% [ 124, 125 ]. As known, linoleic is an essential fatty acid for humans that cannot be synthesized in human bodies.
- What are the disadvantages of pressing corn germ oil?
- The pressing method is to squeeze the oil out through mechanical pressure, which is a method commonly used in oil factories. The process of this method is relatively simple, the supporting equipment is scarce, and the quality of the prepared corn germ oil is good, but its disadvantages are lower oil production efficiency and more serious waste.
- What is the lipid content of corn germ?
- With the development of the corn processing industry, oil has become one of the important products of corn deep processing. Generally, the lipid content of corn germ is about 18%¨C41%, which accounts for more than 80% of the amount of the total lipid in corn.
