Development of Mixed Beverage of Red jujube,Hawthorn and Aloe

With red jujube,hawthorn and aloe as main materials to develope compound beverage with unique flavor,sugar and citric acid were used as excipients. The raw materia juice formula was optimized with taking sensory evaluation as the reference index by single factor and orthogonal experiments,the mixed stabilizer was optimized with taking centrifugal sedimentation rate as the reference index by single factor and response surface methodology. The results showed:On the basis of single factor experiments,raw material juice formula:red jujube juice 20%,hawthorn juice 11% and aloe juice 40%,the mixed stabilizer formula:xanthan gum 0.086%,carboxymethyl cellulose sodium 0.13% and gellan gum 0.037%,the sensory evaluation score of mixed beverage was 93.1±0.9 score,and the centrifugal sedimentation rate was 0.43%±0.015% under optimum formulation conditions. The mixed beverage had a orange color with the proper acidity and sweet taste,releases unique aroma of red jujube,hawthorn and aloe without precipitation or stratification. The research results had some reference value.
