摘　　要：海带富含褐藻胶、纤维素和半纤维素等成分,是生产膳食纤维的优质原料。本文以海带为原料制备海带膳食纤维,并开展了海带膳食纤维与两种常见膳食纤维的理化性质及通便作用的比较研究。结果表明,海带膳食纤维持水力和膨胀力优于燕麦膳食纤维和魔芋膳食纤维;在通便实验中,小鼠给予海带膳食纤维一段时间,小鼠墨汁推进率和便秘模型小鼠排便粒数以及排便重量均明显优于空白对照小鼠以及其他膳食纤维处理小鼠。上述研究表明海带膳食纤维各项生理指标作用最好,并具有较好的通便作用。Saccharina japonica,whichcontains plenty of alginate,cellulose and semicellulose,has been considered an excellent resource of dietary fiber.In this study,dietary fiber was extracted from S.japonica,and its physico-chemical properties and laxative effect were investigated and compared with dietary fiber fromoat and konjac.The results showed thatdietary fiber from S.japonica exhibitshigher water holding capacity and expansion capacity than those from oat and konjac.Also,in the vivo laxative experiment,a better laxative effect was observed in mice treated with dietary fibermade from S.japonica.These results indicated that dietary fiber from S.japonica has excellent physiochemical properties and laxative effect,and might be a potential agent to prevent constipation.
