摘  要:
为了更好地开发和利用番木瓜籽,采用超声波辅助提取法提取番木瓜籽多酚,以多酚提取量为指标,通过单因素和正交试验,探讨乙醇体积分数、固液比、超声波提取温度和时间对番木瓜籽多酚提取量的影响,并确定番木瓜籽多酚的最佳提取条件。结果表明,番木瓜籽多酚提取的最佳工艺条件为乙醇体积分数60%、固液比1∶35、超声波提取温度40℃、超声波提取时间30min,各因素对多酚提取量的影响均呈极显著水平,在此条件下番木瓜籽多酚的提取量为2 916.5mg/kg。

摘  要:
To better exploit and utilize the papaya seed,polyphenol was extracted from papaya seed by ultrasonic-assisted method,and the effects of ethanol concentration,solid-liquid ratio,ultrasonic extracting temperature and time on the extraction amount of polyphenol were studied,and the optimum extraction parameters were confirmed through the single factor and orthogonal experiments.The results showed that the optimum ethanol concentration was 60%,solid-liquid ratio was 1∶35(m/V),ultrasonic temperature was 40 ℃ and time was 30 min.These factors had significant influence on extraction amount of polyphenol.Under this optimum condition,the extraction amount of polyphenol was 2 916.5 mg/kg.
