中文摘要: 采用复合酶法提取海带多糖，将提取的海带多糖浓缩后与菊花和甘草配伍，用喷揉法制成复方海带多糖袋 泡茶。在单因素试验的基础上，通过正交试验，得出提取海带多糖的最优条件。以感官指标为评价标准，筛选出口感 好、营养成分搭配合理的最佳配方。试验结果表明海带多糖的最佳提取工艺为加入海带粉重 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 pH 6.0、 温度 50 ℃条件下酶解 3 h， 在此条件下海带多糖的得率为14.80 %。复方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/mL）与菊花甘草混合物的质量比为 2∶1，其 中菊花和甘草的质量比以 5∶1 最好。复方海带多糖降脂茶该配方可掩盖海带的藻腥味，茶汤清爽可口，具有降脂功能。
Abstract:To development of the compound teabag with kelp polysaccharide. To takes the kelp as the raw ma－ terial， compound enzyme is used to extract kelp polysaccharide， at the same time， studied the compound lipid-lowering teabag base on kelp polysaccharides， chrysanthemum and liquorice. The optimal condition is acquired by orthogonal test. The optimal hydrolysis conditions for kelp polysaccharide extraction from Laminaria japonica was adding 4.0 % compound enzyme（the mass ratio of fiber enzymes， pectin enzymes and papain was 1∶1∶1）， extraction temperature was 50 ℃， extraction time was 3 h and pH value was 6.0. Under these condi－ tions， the extraction yield of polysaccharides was 14.80 %. The best formula of the compound lipid-lowering teabag contain kelp polysaccharide concentrate （the density was 1.2 g/mL） and the mixture of chrysanthe－ mum and licorice. Their quality ratio was 2∶1. The best quality ratio of chrysanthemum and licorice was 5∶1. This recipe with function of reducing blood fat can mask algae smell of kelp and the tea soup taste fresh and de－ licious.
