摘要:

通过响应面试验设计,优化高压脉冲电场提取栀子中的栀子黄色素工艺。采用Box-Behnken响应面法,在单因素试验的基础上,以栀子黄色素提取率为响应值,以脉冲电场强度、乙醇体积分数、料液比和脉冲数为考察因素,进行四因素三水平试验。根据回归方程优化,栀子黄色素提取最佳工艺条件为电场强度25 kV·cm-1,乙醇体积分数28%,料液比1∶18 g·mL-1,8个脉冲数,在此工艺下栀子黄色素提取率为(9.13±0.53)%,由回归方程得出的理论预测数值为9.18%,与实际结果基本一致。结果显示,在栀子天然食用色素的提取中运用经响应面法优化的高压脉冲提取工艺,具有简单可靠的优点,为栀子黄色素的工业化提取提供了可靠的理论依据。

Abstract:

In this study, the extraction technology of gardenia yellow pigment was optimized through response surface test design. Based on single-factor experimental results, a Box-Behnken response surface methodology was employed to design a 4-factor 3-level experimental scheme. With gardenia yellow pigment extraction yield as the response variable, the investigation focused on pulsed electric field intensity, ethanol volume fraction, solid-to-liquid ratio, and pulse times as critical process parameters. According to the regression equation, the optimal extraction conditions were obtained as follows: Electric field strength was 25 kV·cm-1, ethanol volume fraction was 28%, solid-liquid ratio was 1∶18 g·mL-1, pulse times was 8. Under these conditions, the comprehensive score was(9.13±0.53)%, which was basically consistent with the theoretical prediction value of 9.18% by the regression equation. In conclusion, the high voltage pulsed electric field assisted extraction process optimized by response surface methodology is simple and reliable in the extraction of gardenia yellow pigment, providing a theoretical basis for large-scale extraction of gardenia yellow pigment.
