响应面法优化合欢花色素的提取工艺
|
摘要
建立溶剂浸提法提取合欢花色素的优化工艺模型,为其在食品工业中的应用提供理论依据。以合欢花提取液的色价值为考察指标,在单因素试验的基础上,利用响应曲面统计法的Box-Behnken模型对影响色素提取的关键因素进行优化。结果表明:各因素对提取液色价值的影响次序为液料比<乙醇体积分数<提取温度<提取时间,所得优化工艺条件为提取温度70℃、乙醇体积分数51%、液料比31∶1(m L/g)、提取时间41min,该条件下提取液的色价值为886.16,与理论预测值相对偏差为0.88%。本研究所建立的合欢花色素优化工艺模型在实践中具有可行性。
Optimal conditions model for the extraction of pigment from albizia julibrissin were established in order to provide theoretical basis for its application in food. On the basis of single factor experiment, using color value of albizia julibrissin as the indexes, Box-Behnken design was used to optimze the key process parameters. The results showed that the influence orders of each factor on color value were liquid-to-solid ratio
