【摘要】 以超临界CO2 流体萃取技术制备的姜油树脂为试材 ,采用管碟法结合MIC液体稀释法 ,对其抑菌性分别作了定性与定量研究。结果表明 ,生姜油树脂对试验中几种测试菌均有不同程度的抑制作用 ,尤其对真菌的抑制作用明显强于食品常用防腐剂山梨酸钾。其MIC值分别为桔青霉 3.91mg/mL ,酿酒酵母 7.81mg/mL ,金黄色葡萄球菌 15.6 3mg/mL ,大肠杆菌 6 2 .50mg/mL更多还原

【Abstract】 Ginger oleoresin, which made from supercritical CO 2 fluid extraction, was studied on its inhibition to molds, bacteria and yeast cell. Both cylinder plate assay and MIC test demonstrate that ginger oleoresin is of obvious inhibition activity. And its inhibition to fungi was much stronger than the common food preservatives-potassium sorbate. The minimum inhibition concentration (MIC) of ginger oleoresins to the microorganisms in test was P. cierimon 3.91mg/mL, S. cerevisiae 7.81mg/mL, S. aureus 15.6mg/mL and E.coli 62.5mg/mL respectively.更多还原
