超声波辅助法提取胭脂萝卜色素的工艺研究

Study on extracting technology of pigment from carmine radish by ultrasonic-assisted method

  • 摘要: 以胭脂萝卜为原料,对超声波辅助法提取胭脂萝卜色素工艺进行优化。在单因素实验基础上,进行响应面优化实验,以提取率为指标,确定了超声波辅助法提取胭脂萝卜色素的最佳工艺条件:采用50%乙醇为浸提剂,在液料比为42.6∶1、提取时间为50min、提取温度70℃、浸提剂pH4.6时,提取率最高为75.15%;采用超声波辅助法提取胭脂萝卜色素其的提取率明显高于乙醇浸提法。 

     

    Abstract: Using carmine radish as raw material, the extraction technology of pigment from carmine radish by ultrasonic-assisted was optimized. Based on the single factor experiments, and used the response surface optimization experiments, and made the extraction yield as the index, the best technological conditions of ultrasonic-assisted method were determined. Under the conditions of the ethanol concentration 50% , liquid-solid ratio 42.6∶1, the extraction time 50min, extraction temperature was 70℃, pH4.6, the extraction yield was the maximum. Extraction yield of ultrasonic-assisted method was obviously higher than ethanol extracted method, and the extraction yield was 75.15%.
