海南野生与养殖琼枝麒麟菜形态和成分对比

The Morphological Comparison and Component Analysis between the Wild and Farmed Eucheuma of Hainan

对海南野生和养殖2种不同来源的麒麟菜进行了形态和成分对比。结果表明,野生麒麟菜藻体大、分枝数多且长,2种麒麟菜主要成分为碳水化合物,由膳食纤维和可溶性糖组成,野生麒麟菜可溶性糖含量高于养殖麒麟菜,而养殖麒麟菜膳食纤维含量和卡拉胶得率则较高。2种麒麟菜成分组成各有优劣,应根据麒麟菜的实际用途来选择最佳原料。

The morphological comparison between the wild and farmed Eucheuma of Hainan shows that the wild Eucheuma has been greater frond, more number branches, and longer branches. The ingredient measured shows that the mainly component of the wild and fanned Eucheuma is the carbohydrate which composited by dietary fiber and soluble sugars. The soluble sugars of wild Eucheuma is higher than the one of farmed Eucheuma, the dietary fiber and carrageenan of farmed Eucheuma is higher than the one of wild Eucheuma. The advantages and disad- vantages of ingredient are similar between the wild and fanned Eucheuma, which advocate selecting the different Eucheuma as the best materials according to the actual application.
