摘要
Abstract
A method utilzing supercritical CO2 fluid extraction (SFE-CO2) technology to extract peanut oil was described. The optimum technological conditions were obtained by single-factor and response sur- face experiments, and the effect of parameters such as peanut granularity, extraction pressure, time, temperature and supercritical CO2 flow on extraction rate were investigated. The highest extraction rate of 96.16% was achieved under the optimum extraction conditions of 20 mesh peanut, 20 L/h CO2 flow, the pressure of 24 MPa, and 43℃ for 110 min. The unsaturated fatty acids content of peanut oil with the SFE-CO2 fluid extraction (mainly linoleic acid and oleic acid) reached as high as 78% , in line with the level of first-class peanut oil standard.关键词
