毛酸浆枸杞液体营养饮料研制及其对运动抗疲劳作用的研究

以毛酸浆和枸杞为主要原料,优化毛酸浆汁、枸杞汁、木糖醇、柠檬酸的最佳添加量,并探究饮料的抗疲劳特性。结果表明:营养饮料的最佳工艺参数为毛酸浆汁20%、枸杞汁7.5%、木糖醇8%和柠檬酸0.13%,感官评分为92.52,对感官评分影响程度为毛酸浆汁>枸杞汁>柠檬酸>木糖醇。小鼠疲劳实验结果表明,灌胃毛酸浆枸杞液体营养饮料量越大,游泳时间越长,运动能力提升越明显,因此,毛酸浆枸杞液体营养饮料具有抗疲劳的功效,可以作为健康的运动饮料推广使用。

Development of Physalis pubescens L.and Wolfberry Compound Liquid Nutrition Beverage and Its Anti-fatigue Effect on Sports

In this experiment,Physalis pubescens L. and wolfberry were used as the main raw materials to optimize the optimal addition amount of Physalis pubescens L. juice,wolfberry juice,xylitol,and citric acid,and explored the anti-fatigue characteristics of beverages. The results showed that the best process parameters for nutritional beverages were:20 % Physalis pubescens L. juice,7.5 % wolfberry juice,8 % xylitol and 0.13 % citric acid,the sensory score of the beverage was 92.52,the degree of influence on the sensory score was Physalis pubescens L. juice > wolfberry juice> citric acid> xylitol. The results of the mouse fatigue test showed that the greater the amount of lycium barbarum liquid nutrient drink,the longer the swimming time,and the more obvious the improvement of exercise capacity. Therefore,the liquid nutrient beverage had anti-fatigue effect and could be used as a healthy promotion of sports beverage.
