摘  要:
研究潮州柑果皮中黄酮的提取工艺条件及其在果冻防腐中的应用。结果表明,潮州柑果皮中黄酮提取的最佳工艺为乙醇体积分数70%(V/V);料液比1:30(g/mL);提取温度60℃、超声波功率80W,提取时间80min条件下,潮州柑果皮提取物中黄酮含量为(49.49±2.13)mg/g;功能性实验表明,黄酮提取物对羟自由基具有较好的清除作用,其IC50为0.7073mg/mL;防腐抑菌实验表明,潮州柑果皮提取物具有一定的抑菌作用,黄酮类提取物质量添加为1.5%时对果冻的防腐效果较好。

摘  要:
In this study the extraction of flavonoids from Chaozhou tangerine pericarp and its antimicrobial application in jelly were studies.The results demonstrated that the optimal extraction parameters were ethanol concentration of 70%(V/V),materialto-liquid ratio of 1:30(g/mL),extraction temperature of 60 ℃,ultrasonic power of 80 W and extraction time of 80 min.The content of flavonoids in the extract obtained under these conditions was(49.49 ± 2.13) mg/g.The tangerine pericarp extract revealed strong hydroxyl radical-scavenging activity with IC50 of 0.7073 mg/mL and had better antimicrobial effect jelly at a dose of 1.5%(V/V).
