Abstract: Primary research on Corbicula fluminea polysaccharides beverage polysaccharide technology was carried out by extracting polysaccharide in Corbicula fluminea through enzymatic hydrolysis by Chinese wolfberry extract. By considering the enzyme amount, enzymatic hydrolysis time, and material liquid ratio, orthogonal experiments [L9(34)] were carried out to obtain the optimize experiment conditions which the enzymatic hydrolysis time of 90 minutes, enzyme amount of 1.5%, material liquid ratio at 1:6, enzymatic hydrolysis temperature at 55℃, and pH of 7.5, and under which the yield of polysaccharide containing in Corbicula fluminea was 312.6 mg/100g. The best formula of Corbicula fluminea polysaccharides beverage, which was determined through orthogonal experiment method, were as follows: Corbicula fluminea polysaccharide extract（1 mg/ml）of 45 mL, Chinese wolfberry extract of 9 mL, and Spice extract of 0.3%. Used the sensory evaluation as comprehensive evaluation index, a Corbicula fluminea polysaccharides beverage was developed with natural taste and favor of Corbicula fluminea, fresh salty sweetness, refreshing and pleasant, as well as weak smell.
