Carrageenan is extracted from red algae originating from Ireland, growing along the coasts of England, France, Spain, Island…
Product information
- Appearance: Coarse powder, fine powder, and almost odorless.
- Color: Slightly yellow, light yellow or white.
- Solubility: Insoluble in ethanol, soluble in water at a temperature of about 80 o C to form a viscous or milky white fluid solution; Disperses more readily in water if initially moistened with alcohol, glycerol, or a saturated solution of glucose and sucrose in water.
- Viscosity: depends on carrageenan type, molecular weight, temperature, ions present, and carrageenan content; Viscosity is proportional to content.
STABILITY OF CARRAGEENAN
- Carrageenan is stable and most effective in alkaline or neutral environments, insoluble in alcohol and other organic solvents.
- Degradation of Carrageenan powder can occur if there is acid in the mixture leading to lower viscosity and weak gel strength
- At low pH, the colloidal state and product stability are good as in the case of water jelly, jelly jelly…
POSSIBILITY OF REACTIVITY IN PRODUCTS
- Carrageenan is compatible with most hydrocolloids except Gelatin at low pH pH ≤ 5.0
- Carrageenan is incompatible with organic solvents such as alcohol at concentrations above 30%,
- leading to poor bonding ability and easy melting.
- Highly soluble substances (≥60% sugar, ≥20% salt) reduce the solubility of Carrageenan
- Because sugar and salt tend to be highly soluble in water, they will reduce the hydration capacity of Carrageenan in the product.
SOLUTION IN PRODUCTS
- Carrageenan must be dissolved in a liquid solution and stirred well. Carrageenan should be slowly added into the solvent (liquid solution).
- Dissolve Carrageenan powder in water or liquid solution at medium temperature. Never add Carrageenan directly to a high-temperature liquid solution as it will cause poor solubility.
- To dissolve easily and to avoid clumping, mix carrageenan with other ingredients such as Sugar, Salt, Spices… Carrageenan can be wetted with oil solutions or Sorbitol or glycerin to increase solubility. of Carrageenan when used


- Carrageenan is a stabilizer in milk.
- Carrageenan is a thickener in soft drinks.
- In food, carrageenan is used to create gels, thickeners, and stabilizers in products such as soft candy, sausages, canned meat, ice cream, jam, soup, beer, and bread.
- In pharmaceuticals, it is used to produce tablet products, etc.
