Abstract:
A new technique for extraction of corn germ oil via enzymatic hydrolysis was developed. The optimum ratio of raw material to liquid, the size of corn germ, cellulose dosage, protease dosage, reaction time for cellulose-catalyzed hydrolysis and for protease-catalyzed hydrolysis were 1:0.5, 120 mesh, 5000 U/g, 500 U/g, 6 h and 3 h, respectively. Under these conditions, the oil extraction rate reached 98.3%.
