枸杞提取液复合营养素运动饮料的研究

Study on Complex Nutrients Sports Drink

采用热水浸提法提取枸杞提取液,将枸杞提取液与氨基酸、维生素等原料复配,制成复合营养素运动饮料。采用L9(34)正交试验的方法对枸杞的提取温度、提取时间及料液比的正交试验来确定枸杞提取液的最佳提取条件,对加入的枸杞提取液、蔗糖、柠檬酸和氯化钠用量的正交试验来确定复合营养素运动饮料的最佳配比。实验表明,最佳的枸杞提取液提取工艺为料液比1:10,温度80℃,时间75min,最佳的复合营养素运动饮料配方为枸杞提取液250mL/L、糖量80g/L、柠檬酸量1g/L、氯化钠0.5g/L,天冬氨酸0.593g/L、甘氨酸0.841g/L、缬氨酸0.255g/L、赖氨酸0.400g/L、异亮氨酸0.225g/L。维生素B60.010g/L、维生素B120.0002g/L、维生素C1.5g/L。

Exacted by hot water extraction lyceum barbarum polysaccharides（LBP） from Lycium barbarum,using LB,amino acides,and vitamins as main materials mixture,a complex nutrients sports drink was developed.The optional extraction process condition and optional formula were determined by L9（34） orthogonal test.The results showed optional extraction process condition were： the addition of Lycium barbarum,was 9.9%,treatment temperature was 800C,treatment time was 75min.The optional formula of complex nutrients sports drinks were： the LBP 250ml/L,glucose was 80g /L,citric acid content was lg/L,Nac1 was 0.5g/L,aspartic acid was 0.593g/L,Glycine was 0.841g/L,Valine was 0.255g/L,Lysine was 0.400g/L,IIoleucine was 0.225g/L,VB6 was 0.010g/L,VB12 was 0.0002g/L,VC was 1.5g/L.
