| 摘 要： | 研究了红曲米中水溶性色素的超声波辅助提取法的提取工艺.在单因素实验的基础上,采用响应面法研究了超声时间、液料比和超声功率对提取液色价的影响,建立了二次回归模型,得到了提取工艺的最优条件.研究结果表明以上3因素对红曲米中水溶性色素的提取均有显著影响.在提取工艺条件:超声时间为20.6 min,液料比为32.2∶1,超声功率为730 W下提取,红曲米中水溶性色素的色价达到最大值,为570.5 U/g.

| Abstract: | The extraction technology of water-soluble pigment from red kojic rice was studied.On the basis of single-factor experiment,the response surface methodology was used to study the effects of ultrasonic time,material solvent ratio and ultrasonic wave power on the water-soluble pigment extraction.A quadric regression model for the water-soluble monascus pigment concentration was established,and the optimum extraction conditions were obtained.It showed that all the three factors played important roles to water-... |
