摘要
用正交实验对大枣红色素的提取工艺条件进行了筛选,得出最优提取条件为:在80℃下,用16倍于枣皮粉的80%乙醇,超声波浸提30min。同时研究了光照、pH值、H2O2、Na2SO3等因素对色素稳定性的影响,结果表明大枣红色素除在强氧化剂H2O2和碱性环境中稳定性较差外,在其他条件下均具有良好的稳定性。
Extraction conditions of zizyphus pigment were discussed and the optimum extraction conditions were determined by orthogonal test. The results of orthogonal test showed that the optimum extracting conditions were: temperature was under 80℃, ultrasonic extracting time 30 minutes and the proportion of materials 1:16.The effects of different conditions such as light, pH, H2O2 and Na2SO3 on the stability properties of pigment were also discussed.
