Pure Refined Carrageenan 100gm

Carrageenan is made up of sodium, potassium, magnesium and calcium sulphate esters of galactose and 3, 6-anhydrogalactose units. It is a wholly natural ingredient obtained from certain species of red edible seaweed called the Class Rhodophyceae. The popular sources for Carrageenan are the ChondrusCripus, EucheumaCottonii and EucheumaSpinosum species.

The Chondruscrispus species grows mainly in cold water territories such as the northern coasts of the Atlantic while the Eucheuma species are abundantly found in tropical climates like the Philippines. The Philippines has successfully launched and maintained numerous EucheumaCottonii and EucheumaSpinosum seaweed farms providing ample supply and good quality to meet the growing demand.

There are three Carrageenan types which are of commercial interest because of the various applications of hydrocolloids in food and other industrial uses. They are called the Iota, Kappa and Lambda Carrageenan. Marine Hydrocolloids Carrageenan uses the EucheumaCottonii for the production of Kappa Carrageenan and the EucheumaSpinosum for Iota Carrageenan. ChondrusCrispus species is used for production of Lambda Carrageenan.

Product Description

There are many ways to produce Carrageenan.

Marine Hydrocolloids Carrageenan selects only the best method to produce both refined and semi-refined Carrageenan (SRC). These methods are delicate and technically sophisticated processes. The Eucheuma seaweeds are sundried to preserve quality before the production process. Prior to extraction the raw materials are classified and washed to remove sand and salt.

Carrageenan is extracted from the seaweed by alkali treatment at high temperature. The extract is then purified and converted into powder. This is done either by the gel-press, KCI-freezing, KCI-press, or alcohol precipitation method.

At the heart of the manufacturing process is the Quality Control Laboratory. Highly-trained chemists and food technologists continually ensure that the quality parameters are strictly followed and that the Carrageenan being processed passes the specification on:

  • pH
  • Viscosity
  • Gel Strength
  • Protein Reactivity and
  • Other test parameters for the intended application

Commercial Carrageenan is usually standardized by blending different batches of Carrageenan and or adding other gums and salts to obtain the desired gelling or thickening properties.


We also have different blends of Carrageenan specifically for various application. Some of them are given here.
Over and above more blended products are made for various purposes.
