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。
