What are the methods used for extraction of maize (Zea mays L) germ oil?
Methods used for extraction of maize ( Zea mays L.) germ oil – a review The composition of corn oil obtained by the alcohol extraction of ground corn Sequential extraction processing of flaked whole corn: alternative corn fractional technology for ethanol production Corn oil production process.
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 aqueous ethanol extract corn germ oil?
This result proved the preponderance of aqueous ethanol method again. In this study, an efficient and eco-friendly extraction process was developed by the aqueous ethanol extraction with steam explosion pretreatment for obtaining corn germ oil.
What is corn germ?
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.
