Abstract: Objective:Using Lingwu long jujube and cistanche as raw materials to develop a beverage have sweet tasteand rich nutrition.Methods:Optimization of cistanche- Lingwu long jujube beverage formulation by fuzzymathematical sensory combined with response surface,and the contents of total polysaccharide,total polyphenols,flavonoids and antioxidant activities in the optimized product were determined. Results: The optimal ratio of beveragewas determined by response surface analysis as 40% of long jujube juice,16% of cistanche juice,6% of xylitol and0.12% of citric acid. The contents of total polysaccharide,polyphenol and flavonoid of the beverage prepared underthe optimal formula were 2.07mg/mL,0.25mg/mL and 0.09mg/mL,respectively. The antioxidant test results showedthat the total antioxidant capacity of the beverage was 0.91μmol FeSO4/mL,the scavenging ability of hydroxyl radicaland superoxide anion radical was 0.7mg VC/mL and 0.112mg VC/mL. Conclusion: The beverage of cistanche- longjujube optimized by fuzzy mathematical sensory evaluation and response surface method has clear and sweet taste,harmonious aroma and rich nutrition.
