Carrageenan is obtained by aqueous extraction of natural strains of seaweeds of Gigartinaceae, Solieriaceae, Hypneaceae and Furcellar iaceae, families of the class Rhodophyceae (red seaweeds). No organic precipitant shall be used other than methanol, ethanol and propane-2-ol. Carrageenan consists chiefly of potassium, sodium, magnesium and calcium salts of polysaccharide sulphate esters which, on hydrolysis, yield galactose and 3,6-anhydrogalactose. Carrageenan shall not be hydrolysed otherwise chemically degraded.

Carrageenan is a kind of natural polysaccharides hydrocolloid which is present in the structures of certain varieties of red seaweed. These carbohydrates have the ability to form, at very low concentrations, thick solutions or gels in aqueous media.
Konjac Gum main ingredients is Konjac Glucommanan(KGM)with high purity of more than 85% on dry basis. White in color, fine in particle size, high viscosity andwith no special smell of konjac, stable when dissolved in the water.
Xanthan gum, a high-molecular hydrophilic colloid, provides excellent thickening and stabilizing in systems based on its unique pseudo-plastic rheological behavior. It is produced by fermentation of corn starch with xanthomonas campestris.
Sodium alginate, sometimes shortened to "algin", is present in the cell walls of brown seaweeds, and it is partly responsible for the flexibility of the seaweed. Consequently, brown seaweeds that grow in more turbulent conditions usually have a higher alginate content than those in calmer waters.
Agar is a phycocolloid extracted from a group of red-purple marine algae (Class Rhodophyceae) including Gelidium, Pterocladia and Gracilaria. Gelidium is the preferred source for agars. Impurities, debris, minerals and pigment are reduced to specified levels during manufacture.
Gum arabic is a dried exudate obtained from the stems and branches of Acacia senegal (L.) Willdenow or Acacia seyal (fam. Leguminosae). Gum arabic consists mainly of high-molecular weight polysaccharides and their calcium, magnesium and potassium salts, which on hydrolysis yield arabinose, galactose, rhamnose and glucuronic acid.
It is a carob gum, obtained by purification of the ground endosperm of the seeds of the carob tree (Ceratonia Siliqua L.) It is galactomannan polysaccharide. It is partly soluble in cold water and needs heating in order to achieve it’s full viscosity. It shall be a white powder with a ‘typical’ odour and bland taste. The product does not contain any husk.
The traditional, commercial sources of pectin have been citrus peel and apple pomace. Often this is a waste material from another industry such as apple pomace from a cider producer. Citrus peel has often been the preferred material for pectin manufacture due to its high pectin content and good colour properties.
