Ultrasound-assisted extraction (UAE) was used to extract carotenoids from the carrot pomace. To investigate the effect of independent variables on the UAE, the response surface methodology (RSM) with central-composite design (CCD) was employed. The study was conducted with three independent variables including extraction time (min), temperature (°C), and ethanol concentration (%). The results showed that the optimal conditions for UAE were achieved with an extraction time of 17 min, temperature of 32 °C, and ethanol concentration of 51% of total carotenoids (31.82 ± 0.55); extraction time of 16 min, temperature of 29 °C, and ethanol concentration of 59% for a combination of β-carotene (14.89 ± 0.40), lutein (5.77 ± 0.19), and lycopene (2.65 ± 0.12). The non-significant ( > 0.05) correlation under optimal extraction conditions between predicted and experimental values suggested that UAE is the more productive process than conventional techniques for the extraction of carotenoids from the carrot pomace.
超声辅助提取 (UAE) 被用于从胡萝卜渣中提取类胡萝卜素。为了研究独立变量对 UAE 的影响，采用了中心复合设计 (CCD) 的响应面法 (RSM)。该研究采用了三个独立变量，包括提取时间 (min)、温度 (°C) 和乙醇浓度 (%)。结果表明，UAE 的最佳条件为提取时间 17 min、温度 32°C 和乙醇浓度 51%，总类胡萝卜素得率为 31.82 ± 0.55；提取时间 16 min、温度 29°C 和乙醇浓度 59%时，β-胡萝卜素 (14.89 ± 0.40)、叶黄素 (5.77 ± 0.19) 和番茄红素 (2.65 ± 0.12) 的组合得率最高。在最佳提取条件下，预测值与实验值之间无显著相关性 (> 0.05)，这表明 UAE 是一种比传统技术更有前途的从胡萝卜渣中提取类胡萝卜素的方法。
