Carrageenan (also called carrageen gum) is a kind of natural polysaccharide hydrophilic gum extracted from the sea plant red seaweed. It is usually in the form of white or bit yellow powder, free of smell or taste. Carrageenan gel is heat reversible. Carrageenan can melt into solution after being heated and the solution can coagulate into gel after being cooled. Carrageenan has good water-solubility. It begins to melt at 70°C and completely melts at 80°C. It also has good stability, long-term placement may not reduce the intensity and viscosity. It does not hydrolyze in neutral and alkaline solution, even being heated. When used in combination with konjac gum, locust bean gum and xanthan gum, it can functions as strong coordinator and reinforce, distinctly altering the gel characteristics and making the gel elastic and water-keeping.

Carrageenan, also known as Irish moss gelose or Eucheuman, is a natural hydrocolloid extracted from certain species of red seaweeds. It consists mostly of the calcium, magnesium, potassium and sodium sulfate esters of galactose and 3, 6-anhydrogalactose polysaccharides. Due to its unique characteristics of hydrophile, gelling, thickening, emulsifing and stabilizing, carrageenan is widely used in various fields, such as food industry, chemical engineering and medical research.

selects top quality cultured Eucheuma seaweed harvested in Philippines and Indonesian natural seashore, to extract carrageenan and refine with the most advanced techniques. Product quality is superior than national standard GB15044- 2009 and conforms to WHO JECFA and EU E407 regulations.

Carrageenan has good synergies with many other hydrocolloids, such as locust bean gum, gellen gum, arabic gum and gelatin. Such synernism results in diversified and improved food texture, which has been prevalently applied in processed meat, diary product, gummy candy, cup jelly, beverage and jam etc.


Carrageenan is extensively applied in food, medicine, chemical industry for daily supplies, biological chemistry, building paints, textile printing and agriculture. In food industries, Carrageenan is widely applied in the field of the food industries and daily chemistry industries and medical research etc. In daily chemistry industries, it can be used to the agent for toothpaste, detergent, cosmetics and air clarifier agent and so on.
