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/n;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。

Extraction of Flavonoids from Chaozhou Tangerine Pericarp and Its Antimicrobial Application in Jelly
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), material- to-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). 引用
