Abstract: The optimum size of wheat germ is 40 mesh for extracting oil from it,and 90-second microwave heating for wheat germ is beneficial to the oil extraction. The optimum production conditions of wheat germ oil with immobilized cellulase and immobilized proteinase are as follows:ratio of immobilized celluase to immobilized proteinase 6:1,hydrolysis time 6 hours to 8 hours,pH 6.0 and 60 ℃. Under these conditions,the yield of wheat germ oil is about 71.6%.

Key words: wheat germ oil, immobilized cellulase, immobilized proteinase, technique
