reported a solvent-free aqueous enzymatic oil extraction process that achieved oil yields of 800% using corn germ from a commercial corn germ wet mill [1, 2]. Since our previous report was published new procedures have been reported for the aqueous enzymatic extraction of oil from soybeans [3, 4] and rapeseed [5, 6]. The newly published procedures
A bench-scale aqueous enzymatic method was developed to extract corn germ oil from corn germ from either a commercial corn germ dry mill or corn germ from a newly-developed experimental enzymatic wet milling process (E-Germ). With both types of germs, no oil was extracted when acidic cellulase was the only enzyme used.
