摘要: 以玉米须、绞股蓝提取物为原料,研究玉米须绞股蓝茶饮料的制备工艺,通过正交优化获得饮料的最佳配方,并评估饮料的抗菌及抗氧化活性。结果表明,玉米须绞股蓝复合饮料的最佳工艺配方为玉米须绞股蓝(1:1)提取稠膏5 g,黄原胶和卡拉胶混合物(1:1)0.08%,柠檬酸0.12%,白砂糖14%,在该条件下制备的饮料感官评分可达90.3分;最佳配方下的复合饮料中玉米须绞股蓝提取物混合液能有效抑制金黄色葡萄球菌,而对大肠杆菌、绿脓杆菌、阴沟肠杆菌、肠炎沙门氏菌有一定的抑制作用;不同浓度提取物混合液对DPPH·自由基、羟基自由基(·OH)和超氧阴离子自由基有明显的清除效果。

Abstract: The processing technology of the compound beverage using Stigma maydis and Gynostemma pentaphyllum (Thunb.) Makino as raw material was studied. The optimum formulation of compound beverage was obtained with the orthogonal design, and the antibacterial and antioxidant activities of the beverage were evaluated. The results showed that the optimum technological formula of Stigma maydis-Gynostemma pentaphyllum (Thunb.) Makino beverage was Stigma maydis-Gynostemma pentaphyllum(Thunb.) Makino(1:1) extracts 5 g, xanthan gum and carrageenan mixture(1:1) 0.08%, citric acid 0.12%, sugar 14%. The sensory score of beverage prepared under this condition was 90.3. The optimum formula of Stigma maydis-Gynostemma pentaphyllum (Thunb.) Makino extracts in compound beverage could effectively inhibit Staphylococcus aureus, but had a certain inhibitory effect on Escherichia coli, Pseudomonas aeruginosa, Enterobacter cloacae and Salmonella enteritidis. Different concentrations of extracts in compound beverage had obvious scavenging effects on DPPH·free radical, hydroxyl free radical (·OH) and superoxide anion free radical.
