The aqueous enzymatic method was developed to extract oil from corn germ without hexane or other organic solvents. When using corn germ samples from wet-milling operations, yields ranging from 80% to 90% corn oil were obtained using commercial cellulose, whereas in the absence of enzymes, oil yields were only between 27% and 37%.
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 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.
What is corn germ oil?
Most of the commercial corn oil is extracted from the germ and this is commonly known as ¡°corn germ oil.¡± The germ from wet-milling operations (see Chapter 18) is recovered with up to 50% oil, which must be quickly processed because of its low microbiological and chemical stability.
