| 摘 要： | 文章主要研究了响应面优化迷迭香多酚提取工艺及其抑制李斯特菌活性。通过响应面分析法确定迷迭香多酚的最佳提取条件,即液料比为15,乙醇浓度为56%,超声波功率为376W,超声波时间为38min。迷迭香多酚能在一定程度上抑制李斯特菌的活性,且随着迷迭香多酚浓度提高,抑制程度增大。

| Abstract: | This study mainly researches the optimization of extraction process of rosemary polyphenols by response surface method and their antibacterial activity to Listeria monocytogene . The optimum extraction conditions of rosemary polyphenols are determined by response surface methodology. The ratio of liquid to material is 15, the concentration of ethanol is 56%, the ultrasonic power is 376 W, and the ultrasonic time is 38 min. The rosemary polyphenols can inhibit the activity of Listeria monocytogenes to a certain extent, and the higher the concentration of rosemary polyphenols, the greater the degree of inhibition. |
