The application of corn oil to products of the chemical, pharmaceutical, and food industries is determined by its physical and chemical properties. However, this raw material as well as other vegetable oils has limited application in its unaltered form due to its particular composition of fatty acids and triacylglycerols.
What is the process of industrialization of corn oil?
The process of industrialization of corn oil, in general, is divided into two main stages: the extraction of crude oil which also yields a corn oil cake coproduct and the subsequent refining of the crude oil.
What is a prepress or dual corn oil extraction process?
Fig. 21.1. Flowchart of the typical prepress or dual corn oil extraction process. If the corn germ has high-oil content, as in the case of the one obtained by wet-milling, the operation will require the use of pressure and heat to disrupt cell walls and break the oil containing spherosomes.
What is solvent extraction of corn germ?
Solvent extraction of corn germ is the process of greater industrial use because it allows the effective extraction of practically all the corn oil leaving a defatted germ meal with less than 1% residual oil.
