摘要: 本文研究了超临界CO2萃取大豆渣中β-隐黄素的工艺条件。通过单因素实验筛选萃取温度、萃取压力和萃取时间的工艺水平,通过响应面实验对三个的工艺因素进行优化。优化得到的最佳工艺条件:萃取温度35℃、萃取压力28 MPa、萃取时间51 min,在此条件下,萃取得率为181.32μg/100 g。Abstract: This experiment studied the supercritical CO_2 extraction of soybean dregs beta- cryptoxanthin process conditions. By single factor experiment,screening of extraction temperature,extraction pressure and extraction time the state of the art,applied the response surface affecting the beta- cryptoxanthin extraction yield of three technological factors of optimization.Optimization to got the best technological conditions were as follows: extraction temperature 35 ℃,extraction pressure 28 MPa,extraction time 51 min.On this condition,the extraction yield was 181.32 μg /100 g.
