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.
How is maize germ extracted?
The ma ize germ consists of 80% of oil of maize kernel a s presented in Table 1. The refore, vegetable oils ar e mostly extracted by using so lvent extraction (K emper, 2005). Solvent extraction of maize o il obtained with soxhlet apparatus using solvent as n -hexane (Abdulkadir & Abubakar, 2011).
Does Tempering degerming reduce endosperm fractions in corn germ-bran mixture?
The tempering-degerming process implemented to achieve the corn germ-bran mixture may let more endosperm fractions attached to the germ than the dry mechanical degerming and bran separation implemented by Castelmais. 3.2. Oil recovery and characterization Table 1 summarizes data of yields and oil composition for the different extraction methods.
