Abstract: Corn gluten meal was used as material to extract β-carotene through supercritical CO2 extraction technology.The major affecting factors of the extraction rate of β-carotence were studied by orthogonal test method.The optimal conditions for extracting β-carotene are determined as follows:amount of modifier 10%,extraction temperature 40℃,pressure 20 MPa,and time 150 min.Under the above conditions,the extraction rate is 88.70%.
