The technique used for protein recovery also influenced the mass and protein yield and composition. For all treatments, membrane filtration was a more effective method than isoelectric precipitation for recovering protein from extract. Aqueous enzymatic oil extraction (AEOE) was used to evaluate the oil recovery potential after Germ Wet Milling.
Extraction of oil from ground corn germ using ethanol
corn germ oil was extracted from whole ground corn germ using ethanol as the solvent. The yield of oil was measured as a function of temperature, time of extraction, solvent-to-solids ratio, and ethanol concentration. Optimal conditions were a solvent-to-solids ratio of 4 mL/g corn germ, an ethanol concentration of 100%, 30 min of extraction time, and a temperature of 50°C.
Its oil is commercially obtained from corn germ, which constitutes 5-14% of the weight of the kernel, and contains 18-41% oil (Johnston et al., 2005).

The basic steps in the method involved “churning” the corn germ with various enzymes and buffer for 4 h at 50°C, and an additional 16 h at 65°C, followed by centrifugation and removal of the oil layer from the surface. No hexane or other organic solvents are used in this process. By using oven-dried corn germ
