摘　　要：[目的]研制海带多糖降脂袋泡茶。[方法]采用复合酶法提取海带多糖,将海带多糖提取浓缩液与铁观音茶末和甘草配伍,采用喷揉法制成袋泡茶。在单因素试验的基础上,采用正交试验确定海带多糖提取的最优条件。以感官指标为评价标准,在单因素试验的基础上,通过正交试验,筛选出口感好、营养成分搭配合理的最佳配方。[结果]海带多糖的最佳提取工艺为加入海带粉质量4.0%的复合酶(纤维素酶、果胶酶和木瓜蛋白酶的质量比为1∶1∶1),在p H 6.0、温度50℃条件下酶解3 h,海带多糖的得率为14.80%。海带多糖降脂茶的最佳配方为海带多糖提取浓缩液(ρ=1.2 g/m L)、铁观音茶末和甘草的质量比为35∶20∶3,海带多糖降脂袋泡茶中多糖含量为6.0%。[结论]海带多糖降脂袋泡茶配方保存了海带和茶的清香,味道柔和适口,还含有海带多糖和茶多酚等功效成分,具有较好的保健效果。[ Objective] To develop lipid-lowering tcabag with kelp polysaccharide. [ Method] Taking the kelp as the raw material, compound enzyme method was used to extract kelp polysaccharide. At the same time, the compound lipid-lowering teabag base on kelp polysaccharides, Tieguanyin tea fanningss and liquorice were studied. The optimal condition was acquired by orthogonal test. [ Result ] The optimal hydrolysis conditions for kelp polysaecharide extraction was adding 4.0% compound enzyme（ the mass ratio of fiber enzymes ,pectin enzymes and papain was 1 ： 1 ： 1 ） , extraction temperature of 50 ℃, extraction time of 3 h and pH value of 6.0. Under these conditions, the extraction yield of polysaccharides was 14. 80%. The best formula of the lipid-lowering teabag contained kelp polysaecharide concentrate （the density was 1.2 g/mL） ,Tieguanyin tea fanningss and licorice . Their quality ratio was 35： 20： 3. The content of polysaccharide was 6.0% in kelp polysac- charities lipid-lowering teabag. [ Conclusion] This recipe with function of reducing blood fat tasted good and kept the fragrance of kelp and tea. The teabag contains functional contents including kelp polysaccharide and tea polyphenols and has good health effects.
