Alginates
Manufacturing process
The process is based on the following two properties:
- Sodium and potassium Alginates are soluble in water
- Alginic acid and its calcium salt have very low water solubility.
The manufacturing process includes four main steps:
- Demineralization
- Extraction
- Precipitation of alginic acid
- Neutralization and obtention of alginates

Alginates are produced in Lannilis (Brittany), France close to the harvesting coast.
