Iota carrageenan

Iota carrageenan is a high molecular weight hydrophilic polysaccharide primarily extracted from the marine red algae Eucheuma denticulatum "Spinosum" using advanced processing technology. Its sulfate ester polysaccharide content can reach up to 32%, making it a polysaccharide with good immune activity. Under the influence of calcium ions, Iota carrageenan can form a soft and elastic gel, also known as calcium-sensitive carrageenan.

Foodchem selects high-quality seaweed from Indonesia, Tanzania, the Philippines, and Chilean waters as raw materials for carrageenan production. It has established carrageenan production bases in Indonesia and China to ensure a stable supply chain. With advanced processing technology, strict quality management, and more than 20 years of accumulated application solutions for carrageenan in various fields such as meat products, desserts, dairy products, daily chemicals, pharmaceuticals, and pet foods, it can meet the needs of different customers for carrageenan.

Production Process

Iota carrageenan

Product Characteristics


  • Low-temperature dissolution as a pseudoplastic fluid (50-3000cp viscosity)
  • Forms a viscous solution with free dispersion of carrageenan molecules
  • Generally has a viscosity of 20-60cp (1.5%) after heating

  • Forms highly elastic gels with divalent calcium ions after heating
  • Can also form gels with monovalent potassium or sodium ions, no syneresis
  • Forms elastic gels in sugar systems

    Freeze-thaw stability:
  • Iota carrageenan gels do not exude water after refrigeration
  • No syneresis after freezing and thawing

    Protein reactivity:
  • Weak protein reactivity with some emulsification properties
