海带多糖饮料的研制

Development of Kelp Polysaccharide Drink

以海带为主要原料,采用复合酶解法提取海带多糖,通过正交试验,得出提取海带多糖的最优条件。同时研究海带水解液的理化性质,并确定海带多糖饮料的配方,将其配制成饮料。结果表明,海带多糖的最佳提取条件为,加入海带粉重1.0%的复合酶,在pH 6.0、50℃酶解6 h,海带多糖的得率可达10.25%。其中复合酶(纤维素酶、果胶酶和木瓜蛋白酶)的最佳配比为2∶1∶2(质量比),海带多糖饮料的最佳配方为,海带多糖提取液浓度为50%,柑橘汁浓度为10%,柠檬酸浓度为0.3%,苹果香精浓度为1.5%。

The paper takes the kelp as the primary raw material, composite enzymatic is used to extract polysaccharide, and get the optimal conditions for extraction of kelp polysaccharide according to orthogonal kelp test results. At the same time, studied the physical and chemical properties of kelp hydrolyzate and identified kelp polysaecharide drink recipe, made it into beverages. The results indicate ： the optimum extraction conditions of kelp polysaccharide, kelp polysaccharide yield was 10.25 % when adding 1.0 % of the enzyme of kelp powder weight and enzyme 6 h in pH 6.0, 50℃. The best ratio of enzyme （fiber enzymes, pectin enzymes and papain） was 2：1：2, the best formula of kelp polysaccharide was, the concentration of kelp polysaecharide extract was 50 %, the concentration of citrus juice was 10 %, concentration of citric acid was 0.3 %, the concentration of apple flavor was 1.5 %.
