Manufacture

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 gelation of filtrate in presence of potassium chloride, drying then milling)

Carrageenans Manufacture process

Semi-refined carrageenan, or P.E.S., differs from refined carrageenan in two main respects. 

Firstly, the only permitted raw material for P.E.S. is Eucheuma Seaweed. Secondly, it is obtained by simple alkaline treatment (no extraction and no filtration).

Some Cargill products are only approved for use in certain geographies, end uses, and/or at certain usage levels. It is the customer's responsibility to determine, for a particular geography, that (i) the Cargill product, its use and usage levels, (ii) the customer's product and its use, and (iii) any claims made about the customer's product, all comply with applicable laws and regulations.
