摘要
以小米菜为材料,以吸光度为指标,在单因素试验的基础上采用二次通用旋转试验设计,对小米菜色素的提取工艺进行了优化,建立了色素提取效果与提取温度、液料比、提取时间的二次回归数学模型,并利用该模型探讨了各因素对色素提取效果的影响。结果表明:小米菜色素初步定性为复合色素,可能包含黄酮醇和叶绿素。
The preliminary qualitative of Amaranthus Paniculatus L. pigments using organic solvent method were studied by the comparison of the pigment solubility in different solvents and the maximum absorptions. According to single factor experiment about extraction time,raito of liquid to material and extraction temperature,the extraction technology of Amaranthus Paniculatus L. pigment was optimized by quadratic general rotary design and a quadratic regression equation was established. Also,effects of the factors were investigated by the equation. Results showed the pigment was one of the complex pigment,may contain flavonoids and chlorophyll.
