摘　　要：玉米须富含多种生物活性成分,开发以玉米须为主、其他辅料为辅的茶饮产品对缓解高血压、高血脂、高血糖等有重要意义。梳理当前主要购物APP上玉米须茶饮产品的主要辅料成分,并以黑糯玉米须为主材料,与梳理得出的辅料分别进行搭配,比较质量比在1∶2、1∶1和2∶1条件下水提液中生物活性成分和抗氧化能力。结果表明,8款购物APP销售的139种玉米须茶饮产品中,筛选出了桑叶、山楂、葛根等出现次数占总产品数比例超过20%的13种辅料。黑糯玉米须与大多辅料在质量比2∶1条件下,水提液中总多糖、总皂苷和总黄酮等生物活性成分含量均处于较高水平,但抗氧化能力表现一般。采用隶属函数值法综合考虑生物活性成分和抗氧化能力得出,黑糯玉米须分别与葛根、栀子、菊花、陈皮、苦荞在质量比2∶1搭配下的综合效应最佳。综上,1.5 g黑糯玉米须与0.75 g葛根、栀子、菊花、陈皮、苦荞搭配可作为玉米须袋泡茶潜在的产品进行开发。Corn silk is rich in a variety of biologically active ingredients.The development of tea products based on corn silk and supplemented by other auxiliary materials could be of great significance for alleviating high blood pressure,high blood fat,and high blood sugar.The main ingredients of corn silk tea products on dominating online shopping APPs were sorted out in current study.Then,in order to assess the bioactive substances and antioxidant capacities in the water-extraction of corn silk tea products,an experiment was carried out with corn silk as the main material and other ingredients as supplements under different mass ratios with 1∶2,1∶1,and 2∶1.The results showed that thirteen ingredients were sorted out by analyzing 139 kinds of corn silk tea products sourced from 8 shopping APPs,occurrence times of which were more than 20%of total products number,such as mulberry leaves,hawthorn and pueraria.Under the mass ratio of black corn silk to most ingredients with 2∶1,the contents of total polysaccharides,total saponins and total flavonoids in the water-extraction were higher,but the antioxidant capacity did not show an advantage.The integrated effects of bioactive substances and antioxidant capacities were assessed by subordinate function value method,and it was concluded that corn silk with pueraria,gardenia,chrysanthemum,pericarpium citri reticulatae and tartary buckwheat had better comprehensive effect under the mass ratio of 2∶1.Therefore,1.5 g corn silk with 0.75 g pueraria,gardenia,chrysanthemum,pericarpium citri reticulatae and tartary buckwheat could be used as potential products for corn silk tea.
