摘要
试验以苦荞作为原料,研究苦荞黄酮提取过程中超声波时间、乙醇浓度、料液比、超声波温度对黄酮提取率的影响,通过正交试验研究出最佳苦荞口服液调配工艺。实验表明黄酮最佳提取条件为:超声波时间25 min、乙醇浓度80%、料液比1∶20、超声波温度45℃,此时黄酮的提取率最高,利用最佳提取条件进行苦荞黄酮提取分离,确定调配工艺黄酮浓缩液添加量为80%、安赛蜜添加量为0.25%、木糖醇添加量为5%、山梨酸添加量为0.025%,纯净水补足,此时口味最佳。
The effects of ultrasonic time ,ethanol concentration,solid-liquid ratio and ultrasonic temperature on tartary buckwheat flavonoids yield were studied to determine the optimal extraction condition. The results showed that flavonoids yield was highest when ultrasonic time was of 25 min,ethanol concentration was 80%, solid-liquid ratio was 1:20, and ultrasonic temperature was at 45℃. Optimal formula for oral liquid was studied by the orthogonal experiment design method, and the formula was determined as follows: flavonoids concentrate 80%, acesulfame potassium 0.25%,xylitol 5% water make up 100%.
