摘要：

摘要：利用微波萃取技术对花生壳黄色素的最佳提取工艺进行了研究，实验通过单因素实验和正交实验极差和方差分析，观察了粒度、微波功率、微波时间、溶液pH值、料液比和提取液浓度对提取液吸光度的影响，得出了花生壳黄色素最佳工艺条件为：粒度80目，微波功率360W，微波辐射时间为220s，物料配比为 1g∶15ml，溶液pH值为3，乙醇溶液的体积分数为50%。在此工艺条件下提取液吸光度A385为1.432，固体产品得率为3.26％，色价为8.6，得到的色素产品颜色为黄色，属于黄酮类色素。

Abstract:

Abstract: Yellow pigment was extracted from peanut hulls by the method of microwave-assisted extraction. Using single factor test and orthogonal method, the effects of particle size,the microwave output power, the microwave-assisted extraction irradiation time, the solution pH, material-solvent ratio and alcohol concentration were investigated. The optimal extraction conditions were as follow: particle size 80,microwave output power 360w, microwave-assisted extraction irradiation time 220s, ratios of solvent to material 1g:15ml,pH 3.0, alcohol concentration 50％. Based on these conditions ,the absorptivity A385 was 1.432 ,the yield was 3.26%,the color value was 8.6. The pigment is yellow and belong to flavonoid pigments.
