Study on De-lipid of Corn Fiber by Supercritical CO2 Extraction

Abstract

Abstract: In this paper, the effects of pressure, temperature, CO 2 flow and extraction time were studied by supercrifical CO 2 extraction for de-lipid of corn fiber. The optimum conditions were determined through orthogonal test: the pressure was 30MPa, temperature 45℃, time 60min and CO2 flow rate 23L/h. The rate of de-lipid was 5.06%. The color of product was milk white, the flavor was pure and the content of lipid was below 0.3%. It could be food as additive for low calorie and high dietary fiber food.

Key words: corn fiber, supercritical CO2 fluid extraction, degrease
