| Application | Alginic acid, derived from the walls of brown seaweeds, plays a crucial role in various industries due to its unique chemical structure, consisting of D-mannuronic and L-guluronic acid units. These units form different regions within the alginic acid chain, resulting in varied chemical and physical properties, which are influenced by the species of seaweed. In the presence of calcium ions and acidic conditions, alginic acid forms non-thermoreversible gels, making it valuable for thickening, gelling, and binding applications. This property is extensively utilized in food production, where alginic acid enhances the texture and stability of products like ice cream, puddings, and dessert gels. Its use extends into the pharmaceutical sector as well, where it acts as a binder and disintegrating agent in tablets and capsules, and serves as a thickening and stabilizing agent in creams, gels, and emulsions. Additionally, alginic acid offers therapeutic benefits, functioning as an antacid and being employed in managing gastroesophageal reflux when combined with H2-receptor antagonists. Through its diverse applications, alginic acid underscores its importance as a versatile and vital compound in food, pharmaceutical, and therapeutic contexts. |
