1. Sodium alginate is a by-product of the extraction of iodine and mannitol from the brown seaweed kelp or Sargasso. Its molecule is connected by β-D-mannuronic acid (β-D-mannuronic, M) and α-L-gul uronic acid (α-L-guluronic, G) according to (1→4). Sodium alginate aqueous solution has high viscosity and has been used as food thickener, stabilizer, emulsifier, etc. 2. Sodium alginate is a non-toxic food that was included in the US Pharmacopoeia as early as 1938. Sodium alginate contains a large amount of -COO-, which can show polyanionic behavior in aqueous solution and has certain adhesion, which can be used as a carrier for the treatment of mucosal tissue. Under acidic conditions, -COO- is converted into -COOH, the degree of ionization decreases, the hydrophilicity of sodium alginate decreases, the molecular chain shrinks, the pH value increases, the -COOH group continues to dissociate, and the hydrophilicity decreases. 3. The property of sodium alginate increases and the molecular chain is elongated. Therefore, sodium alginate has obvious pH sensitivity. Sodium alginate can rapidly form gels under extremely mild conditions. When there are cations such as Ca2+ and Sr2+, Na+ on the G unit will undergo an ion exchange reaction with divalent cations, and the G unit will accumulate to form a cross-linked network structure, thereby forming a hydrogel.
