Sodium alginate, potassium alginate, carrageenan
Sodium alginate, potassium alginate, and carrageenan are commonly used food additives, but they differ in chemical structure, properties, and applications.
Firstly, their chemical structures are different. Sodium alginate is a natural polysaccharide composed of α- L-fucosuronic acid and β- A linear copolymer composed of D-glucose, while potassium alginate is composed of α- L-fucosuronic acid and β- Composed of D-glucose and potassium ions. Carrageenan is a high molecular weight polysaccharide composed of D-galactose, D-glucose, and D-glucuronic acid.
Secondly, their properties are also different. Sodium alginate and potassium alginate can form gel in water, and gel has high strength and stability, so it is often used as a stabilizer and gelling agent for making jellies, puddings, oral liquid medicaments, etc. Although carrageenan also has certain gelling properties, it is mainly a thickener and stabilizer, and is often used to make ice cream, sauces, salad dressings, etc.
Finally, they also differ in terms of application. Sodium alginate and potassium alginate are both used in fields such as food, medicine, and cosmetics, while carrageenan is mainly used in the food industry. In addition, sodium alginate and potassium alginate are also commonly used in the production of biomaterials and medical dressings.
In summary, although sodium alginate, potassium alginate, and carrageenan are all food additives, they have differences in chemical structure, properties, and applications, and need to be selected and used according to actual needs.
