摘要

本研究采用三级方框-贝肯响应面设计，在提取温度、超声功率、提取时间和固液比四个因素下对超声辅助提取（UAE）从废弃红甜菜茎秆中提取天然色素进行了优化。提取温度、超声功率和固液比对色素的提取率有显著影响。提取温度为 53 °C，超声功率为 89 w，提取时间为 35 分钟，固液比为 1:19 g/ml。在此条件下，色素的实际产量（甜菜黄素为 1.28 ± 0.02 mg/g，甜菜红素为 5.31 ± 0.09 mg/g）与预测值（甜菜黄素为 1.29 mg/g，甜菜红素为 5.32 mg/g）有很好的相关性。

Multivariate statistical analysis and optimization of ultrasound-assisted extraction of natural pigments from waste red beet stalks.

In this study, ultrasound-assisted extraction (UAE) of natural pigment extraction from waste red beet stalks were optimized under four factors (extraction temperature, ultrasonic power, extraction time and solid-liquid ratio) by using three level Box-Behnken response surface design. Extraction temperature, ultrasonic power and solid-liquid ratio were significantly influenced the extraction yield of pigments. Extraction temperature of 53 °C, ultrasonic power of 89 w, extraction time of 35 min and SL ratio of 1:19 g/ml was identified as the optimal condition. Under this condition, the actual yield of (betacyanin of 1.28 ± 0.02 and betaxanthin of 5.31 ± 0.09 mg/g) pigments was well correlated with predicted values (betacyanin was 1.29 mg/g and betaxanthin was 5.32 mg/g).
