Manufacturing process for refined carrageenan
Industrial production of refined carrageenan consists of three main steps:
- Extraction in alkaline conditions
- Purification by separating the gum from insoluble impurities
- Carrageenan recovery (precipitation in alcohol or gellation of filtrate by the addition of potassium chloride, drying then milling).
