Consumption of sodium alginate on the body and side effects, the right amount of sodium alginate is not bad for the human body. Sodium alginate, sodium alginate has been widely used in the food industry and the field of medicine, which contains a variety of nutrients, is good for the human body, but the amount of use should be appropriate.

Sodium alginate is a by-product after iodine and mannitol are extracted from kelp or sargassum, its molecule consists of β-D-mannuronic acid (β-D-mannuronic, M) and α-L-guluronic acid (α-L-guluronic, G) connected by a (1→4) bond, it is a kind of natural polysaccharides, with the stability, solubility, adhesion and safety required for excipients of pharmaceutical preparations. and safety.

Process and properties of sodium alginate:

The process of sodium alginate is as follows: dry or wet seaweed (algae) is crushed, washed to remove impurities, strong alkaline water extraction, clarified crude alginate solution, precipitated by calcium chloride to get colorful calcium alginate, decolorized, deodorized and then processed with acid to remove soluble impurities precipitated by alginate, sodium alginate with sodium carbonate, and then sodium alginate powder after drying, crushing and sieving.

Sodium alginate is white or light yellow powder, almost odorless and tasteless. Sodium alginate is soluble in water, insoluble in ethanol, ether, chloroform and other organic solvents. Dissolved in water into a viscous liquid, 1% aqueous solution pH value of 6-8, when pH = 6-9 viscosity is stable, when heated to 80 ℃ above the viscosity is reduced.

Sodium alginate is non-toxic, LD50>5000mg/kg. chelating agent on the nature of sodium alginate solution chelating agent can be complexed with the divalent ions in the system, so that sodium alginate can be stabilized in the system.
