For extraction of corn oil, compressed carbon dioxide is fed in a SFE reactor, which contains the flaked germ, with temperature close to 50°C and pressure between 351 and 562 kg/cm 2. After depressurizing the system, the oil is collected in a reservoir.
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 enzymatic extraction of corn oil?
The enzymatic extraction of corn oil is especially promising when applied simultaneously with purely mechanical expelled oil because it significantly enhances yield. The aqueous enzymatic method was developed to extract oil from corn germ without hexane or other organic solvents.
How to extract oil from corn germ without hexane?
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%.
