  A method for the manufacture of carrageenans from bi-component seaweed material, wherein the seaweed is subjected to 1) a heterogeneous reaction step in an aqueous alkaline medium having specific values of alkali concentration, temperature and salt concentration; 2) separation of the solid material from the liquid phase; 3) fractionation of the lambda-family carrageenans from the solid material obtained in 2) by treatment with an aqueous medium; and 4) optionally further purification steps, provides for efficient production and separation of kappa-family carrageenans and lambda-family carrageenans respectively.

  一种利用双组分海藻材料制造卡拉胶的方法，其中海藻要经过 1) 在具有特定碱浓度、温度和盐浓度值的水性碱性介质中进行异相反应步骤；2) 从液相中分离出固体材料；3) 通过水性介质处理，从 2) 中得到的固体物质中分馏出λ族卡拉胶；以及 4) 可选的进一步纯化步骤，从而分别高效地生产和分离出卡帕族卡拉胶和λ族卡拉胶。

  An improved method for the manufacture of gelling carrageenens from seaweed, wherein mono-component seaweed is subjected to a heterogeneous reaction step, one or more washing step (s), and further workup provides for substantial savings in alkali costs as non-expensive alkalis, such as NaOH, Na 2 CO 3 ,Na-phosphates, K 2 CO 3 , K-phosphates, ammonia may be used in the heterogeneous reaction step.
