Carrageenans are polysaccharides (galactose) with varying degree of sulfatation (between 15% and 40%). They are extracted from red seaweeds and are used as thermo reversible gelling agents and thickening agents. Carrageenans can control syneresis. Carrageenans can also be used as a binding agent and can improve texture and mouthfeel. Cargill is a supplier of carrageenan for the food industry.
Types of carrageenan
In general, three major types of carrageenans can be distinguished:
- Alcohol processed refined carrageenans.
- Potassium chloride processed refined carrageenans.
- Semi-refined carrageenan, also called PNG (Philippine Natural Grade) or PES (Processed Eucheuma Seaweed). This has only more recently been approved for food applications.
