Carrageenans
Carrageenans are polysaccharides (galactose) with varying degrees of sulfatation (between 15% and 40%). They are extracted from red seaweed and are used as thermo-reversible gelling and thickening agents, mainly in the food industry.
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)
Carrageenans has only more recently been approved for food applications.
