江蓠是一种富含琼胶的重要经济海藻,随着世界各国琼胶生产的不断发展,作为主要原料海藻的石花菜日益不能满足琼胶生产的需要,以江蓠作原料提取琼胶的工作,已引起有关国家的广泛重视。早在一百多年前,日本就开始用江蓠作提取琼胶的辅助原料,进入二十世纪初期,北美、南非和澳大利亚,也利用当地的自然资源,逐渐发展起以江蓠为原料的琼胶生产。但是,近些年来,工农业生产和科学技术的飞跃发展,对琼胶的需要量也大为增加。据初步了解,目前全世界每年的琼胶消费量,大约为一万多吨,其中仅日本每年就需要二千多
As an important economic seaweed rich in agar, as the continuous development of agar production all over the world, sea buckthorn, as the main raw material of seaweed, can not satisfy the need of agar production increasingly. Work has drawn wide attention from the countries concerned. As early as a hundred years ago, Japan began to use Jiang Shui as a supplementary raw material for agar extraction. In the early twentieth century, North America, South Africa and Australia also used the local natural resources to gradually develop the raw materials Agar production. However, in recent years, the rapid development of industry, agriculture and science and technology has greatly increased the demand for agar. According to a preliminary understanding, the current annual consumption of agar in the world is about 10,000 tons, of which Japan alone needs more than 2,000
