紫菜作为一种大型红藻,是目前世界上人工栽培经济价值最高的一种栽培海藻。全世界人工栽培海藻的总产值近3×10~9美元,其中紫菜的产值近2×10~9美元,约占2/3(费修绠等,1998)。紫菜不仅含有丰富的蛋白质、碳水化合物,而且各种维生素和矿物质的含量也特别丰富(Ruperez et al.,2002;Dinabandhu et al.,2002),其中紫菜的多糖及藻胆蛋白等成分具有药用价值,以紫菜为原料从中提取高附加值的产品。因此,利用紫菜可以开发保健食品和生物药物,其具有很大的市场价值和开发潜力。 Seaweed as a large red algae, is currently cultivated in the world’s highest economic value of cultivated seaweed. The total output of artificially cultivated algae in the world is nearly 3 × 10 ~ 9 US dollars, of which the production of seaweed nearly 2 × 10 ~ 9 US dollars, accounting for about 2/3 (Fei Xiu, et al., 1998). Seaweed is not only rich in protein, carbohydrates, but also rich in various vitamins and minerals (Ruperez et al., 2002; Dinabandhu et al., 2002), in which the laver polysaccharides and phycobiliproteins have medicinal properties Value, with seaweed as raw materials extracted from the high value-added products. Therefore, the use of seaweed can develop health food and biopharmaceuticals, which has great market value and development potential.
