利用废弃油制备杀菌护肤药皂的研究

Study on Preparation of Antibacterial and Skin Protection Soaps with Waste Oil

目的收集家庭生活的废弃油制成药皂。方法超声提法提取薄荷、香薷和蒲公英中有效成分;以黄酮提取率为指标,液料比A、乙醇浓度B、超声温度C、超声时间D做L9(34)正交实验优化黄酮类成分提取工艺;通过抑菌试验确定中药提取物最小抑菌浓度;将收集的废弃油过滤除杂后加入30%NaOH溶液进行皂化,根据抑菌实验结果加入中药提取物制成药皂。结果根据正交实优化最佳提取工艺为料液比1:25、乙醇浓度60%、温度70℃和超声40 min时总黄酮的提取率为最佳,且对大肠杆菌的最小抑菌浓度为0.06 mg/mL。根据QB/T标准进行总游离件和总氯化物检测。抑菌药皂经肥皂标准质量检查合格。结论通过该实验可以利用废弃油制备出质量合格药皂。

Objective The project was to gather family edible waste oil as raw material and to make a medicinal soap.Methods Ultrasonic extraction was used to extract the active constituents of mint,sage and dandelion.The flavonoid extraction rate was used as an index to optimize the extraction process of flavonoids by using L9(34)orthogonal test with liquid material ratio A,ethanol concentration B,ultrasonic temperature C and ultrasonic time D;The bacteriostasis test was used to determine the minimum inhibitory concentration(MIC)of the extracts of Chinese herbal medicine.The collected waste oil was filtered and then added to 30%NaOH solution for saponification.According to the bacteriostasis test result,the traditional Chinese medicine extract was made into drug soap.Results According to the orthogonal optimization of the best extraction process for the solid-liquid ratio of 1:25,the ethanol concentration of 60%,the temperature 70℃and ultrasonic extraction of flavonoids 40min,and the minimum inhibitory concentration of escherichia coli was 0.06 mg/mL.Total free and total chloride detection were according to QB/T standards.Bacteriostatic soap was made by standard quality inspection.Conclusion The qualified soaps were prepared by this process.
