摘要
以玉米为原料,研究微波与表面活性剂水溶液协同提取玉米黄色素,确定十二醇硫酸酯钠盐为玉米黄色素提取的最佳表面活性剂,通过正交实验确定了最佳协同提取条件为:微波辐射档数:中高火,提取时间:50s,二醇硫酸醋钠溶液浓度:0.03%,提取固液料比:1∶80g/mL。对比实验结果表明,采用该法使玉米黄色素的提取率比仅用微波法提高11.6%。
A procedure to extract the red natural pigment from the flower of corn was discussed. The optimum conditions for extraction of the pigment were established as follows: K12 was the appropriate surfactant for extraction and its suitable consistency was about 0.03% ,the extracted power was middle and high radiation, the time was 50 seconds and the extracted solvent was 1 : 80 g/mL. Combining mierowaveassistant technology with dissolution character of surfactants, the extractive proportion of the pigment was 11. 6% higher than only using the microwave-assistant technology.
