摘　　要：以蛹虫草和玉米肽为主要原料,研制具有抗氧化、降血压、提高免疫力、降低血栓倾向等多种功效的功能性饮料,通过正交试验确定最佳配比。结果表明,当V(蛹虫草浸提液)∶V(玫瑰花水)=2∶1、添加10g/L玉米肽、1g/L乙基麦芽酚、80g/L的蜂蜜、0.15g/L的柠檬酸时,饮料的色泽、口感、气味等为最佳。纤溶酶活力为2.78U/mL,虫草素含量为12.43μg/mL,多糖含量为199mg/mL。抗氧化试验结果表明,对于DPPH·、·OH清除能力和还原力,每毫升饮料相当于含有20、40和20μgVc。该饮料具有良好的抗氧化活性和降低血栓倾向的功能,同时该研究为以蛹虫草为基料的功能食品的开发提供一定的借鉴思路。This study used Cordyceps militaris and corn peptides as major materials to develop a functional drink that is antioxidative,antihypertensive,immunoregulatory and able to reduce thrombosis.The optimal formula of the drink was determined by orthogonal experiments.The results showed that when the ratio of Cordyceps militaris extract to rose water was 2∶1,with 10 g/L corn peptides,1 g/L ethyl maltol,80 g/L honey,and 0.15 g/L citric acid,the color,taste,and smell of the drink were the best.Under this condition,the activity of fibrinolytic enzyme in the drink was 2.78 U/mL,and the contents of cordycepin and polysaccharide were 12.43μg/mL and 199 mg/mL,respectively.Moreover,the scavenging effects of each milliliter of the drink on DPPH·,·OH,as well as its reducing power were equivalent to 20μg,40μg,and 20μg Vc,respectively.In conclusion,this study provides some ideas for developing functional foods based on Cordyceps militaris,which has great significance for its utilization.
