摘要
为了优化超声波辅助提取黑豆皮色素的工艺条件,在单因素试验基础上,采用响应曲面法对影响黑豆皮色素提取效果的3个主要影响因素即超声功率、溶液pH值和液固比进行了优化,建立并分析了各因子与黑豆皮色素提取液吸光值关系的数学模型。结果表明:原料用量0.5 g,在超声功率为80 W、溶液pH值1.5、液固比30 mL/g时,黑豆皮色素提取效果较好,在此条件下色素的提取率达到95.6%。
Ultrasonic-assisted extraction of pigments from black soybean hulls was investigated.Based on the single factor experiments,the effects of different ultrasonic power,pH values and the ratios of solution to solid on the extraction yield of pigments from black soybean hulls were optimized with Response Surface Methodology(RSM).A mathematical model was established and analyzed to describe the relationships between the studied factors and the response of the total extraction yield of pigments from black soybean...
