Furcelleran is a gum that is the extract of the red alga furcellaria fastigiata. It swells in cold water and requires heating to 75–80°c for solubilization. It forms thermoreversible gels after heating and cooling and has properties between agar and carrageenan. It is also termed danish agar. It is used in milk puddings, flans, jelly, jam, and gelled meat products. | [EPA Substance Registry System]

| Hazard Information | Back Directory | [Description]
Furcelleran is a hydrocolloid obtained by extraction with water or aqueous alkali of Furcellariafastigiata of the class Rhodophyceae (red seaweeds). It consists mainly of the potassium, sodium, magnesium, calcium, and ammonium sulfate esters of galactose and 3,6-anhydrogalactose copolymers. These hexoses are alternately linked α-1,3 and P-1,4 in the polymer. The relative proportion of cations existing in Furcelleran may be changed during processing to the extent that one may become predominant.
The ester sulfate content of furcelleran ranges from 8% to 20%. In addition, it contains inorganic salts that originate from the seaweed and the process of recovery from the extract. Furcelleran is recovered by alcohol precipitation, potassium precipitation, or by freezing. The alcohols used during recovery and purification are restricted to methanol, ethanol, and isopropanol.
Furcelleran is a brownish or tan to white, coarse to fine powder that is practically odorless and has a mucilaginous taste. It is soluble in water at a temperature of about 80°C, forming a viscous, clear or slightly opalescent solution that flows readily. It disperses in water more readily if first moistened with alcohol, glycerin, or a saturated solution of sucrose in water. | [Chemical Properties]
