Production Methods

The kelp after iodine extraction was stirred and immersed in sodium carbonate solution at 60~80℃ for 2h. The leaching solution was coarsely filtered through 0.54mm sieve cloth, then the kelp residue was removed by emulsification floatation method, and then finely filtered through 0.147mm sieve cloth Clear solution. Adjust the pH value to 2 with hydrochloric acid, the alginic acid gel is precipitated, and add 5% calcium chloride to dehydrate the gel. After pressure filtration, the water content of the gel is below 75%, and the sodium carbonate solution of 6% to 8% is added to make the gel alkaline, and the product is dried after standing for 8 hours.
