Lycium barbarum contains betaine, unsaturated fatty acids, amino acids, and other vitamins, which can nourish the liver, kidney, benefit essence and so on, while roses contain more than 300 kinds of chemical components, such as dendrobium bark glycosides, fatty oil and organic acids, as well as 18 kinds of amino acids and trace elements needed by human body, which have whitening, moisturizing, nourishing face, regulating meridians and so on. In this study, rose powder and wolfberry were used as raw materials. Through single factor experiment and orthogonal analysis, sensory evaluation score was used as the main measurement index, supplemented by its precipitation rate, the raw and auxiliary materials of rose powder and wolfberry composite beverage were tested to determine the best formula and stabilizer ratio. The rose pollen medlar compound beverage with good tissue and taste was prepared by the technology of beverage preparation, and its acidity and soluble solids content were determined by physical and chemical indexes.
