摘要
以番茄果实为研究对象,用黄酮含量作为提取工艺的指标,采用传统加热法和超声辅助法提取番茄总黄酮,并比较2种提取工艺效果;通过单因素试验与正交实验相结合,研究提取时间、提取温度、料液比、提取次数等对番茄总黄酮含量的影响。结果表明:番茄总黄酮的最佳提取工艺为超声辅助法:50%乙醇,提取时间为20min,提取温度60℃,料液比为1∶40mg/mL;在最佳提取条件下,番茄总黄酮的含量为576.95mg/100g。
Taking fruit of tomatoes as research object,the content of flavonoid indicators as the evaluation standard.The total flavonoid of tomato was extracted and compared by using conventional heating and ultrasonic assisted method.Extracted by univariate time,extraction temperature,solid-liquid ratio and extract frequency were conducted to study the flavonoid content of tomato through by single factor experiment and orthogonal experiment.The results showed that the optimum extraction process of flavonnoid in tomato was ultrasound-assisted method：50% ethanol,axtraction time was20 minutes,extraction temperature was 60℃,solid-liquid ratio was 1∶40mg/mL.Under optimal conditions,the content of total flavonoid in tomato was 576.95mg/100 g.
