| 摘 要： | 从樟树果实中提取红色素,检测该色素的抑菌活性及稳定性。结果表明,樟树果实红色素对大肠杆菌、金黄色葡萄球菌和痢疾杆菌的生长有较强的抑制活性,最小抑菌浓度(MIC)分别为4.0mg/mL、1.0mg/mL和3.0mg/mL;该色素经酸、碱、热处理后仍具有较强的抑菌活性;0.1mol/L的Zn2+及0.1mg/mL的淀粉、葡萄糖对该色素的抑菌活性影响较小,0.1mol/mL的Cu2+、Fe3+、Ca2+、Na+等均具增效作用。食品防腐实验表明,该色素有较好的食品防腐作用。

| Abstract: | The antibacterial activity and stability of the red pigment extracted from the fruit of camphor tree were studied.The results showed that the red pigment had stronger antibacterial activity to Escheichia coli,Staphy lococcus aureus and Shigella dysenteriae and MIC were 4.0,1.0,3.0 mg/mL respectively.The red pigment still had stronger antibacterial activity when treated acid,alkali and heating.The antibacterial activities of the red pigment were less affected by 0.1 mol/L Zn2+,0.1 mg/mL starch and 0.1 mg/mL glucose,and could be strengthened by 0.1 mg/mL Cu2+,0.1 mg/mL Fe3+,0.1 mg/mL Ca2+ and 0.1 mg/mL Na+.The food antiseptic experiment showed that the red pigment had much better antiseptic effect. |
