超声法提取番茄油树脂中多酚的工艺研究

Study on extracting polyphenols from tomato oleoresin via ultrasound

采用超声波辅助法提取番茄油树脂中多酚类化合物,对固液比、超声功率、超声温度、提取时间等因素对提取物多酚得率的影响进行了研究。结果表明,最佳提取工艺为:固液比1∶15、超声功率70 W、超声温度50℃、提取时间40 min,在此条件下提取物多酚得率为12.8%,多酚含量高达4.396 mg/g。

Polyphenols from tomato oleoresin were extracted through ultrasound-assisted.The test was designed based on solid-liquid ratio,ultrasonic power and ultrasonic temperature,extracting time as the main research factors.Results show that the optimal technological parameters are as follows:solid-liquid ratio 1∶15,ultrasonic power 70 W,ultrasonic temperature 50℃,extracting time 40 min.Under this extraction condition,the yield of polyphenols is 12.8%and the highest content of polyphenols is 4.396 mg/g.
