Seaweed is harvested throughout the world as a food source as well as an export commodity for the production of agar and carrageenan products. Seaweed has been cultured traditionally for decades and probably for centuries in several Asian nations.
As early as the 1970s, it was recognized that demand for seaweed and seaweed products was outstripping supply and cultivation was viewed as the best means to increase production. The profitable nature of seaweed farming also became evident and accelerated its expansion. Seaweed farming has frequently been suggested as both a means to improve economic conditions and a means to reduce fishing pressure.
Seaweeds are exported either in raw form (fresh or dried seaweeds) or processed form (carrageenan and kelp powder). The major products derived from the utilization of seaweeds are agar, algin or sodium alginate, and carrageenan. Carrageenan is a natural gum used as additive, binder, and emulsifier on food, pharmaceutical, beverage, and cosmetic industries.
