The process of sodium alginate is as follows: dry or wet seaweed (algae) is crushed, washed with water, mixed with strong alkali water, and clarified to obtain a crude alginate solution, which is precipitated by calcium chloride to obtain colored calcium alginate. After decolorization and deodorization, it is treated with acid to remove soluble impurities to obtain alginic acid precipitation, and sodium carbonate is obtained by sodium carbonate, and then dried, pulverized and sieved to obtain sodium alginate powder.
