Of the many red algae used in various areas for the production of agar, the most important agarophytes, such as Acanthopeltis japonica, Ahnfeltia plicata. a number of Gelidium and Gracilaria species which are of commercial value, as well as Pterocladia species are described. Information is given on occurrence, distribution, appearance, and use. Agar is a polysaccharide. Its most important property is the ability to form solid gels. Agar is produced by extraction processes from suitable raw materials. The most important property of agar for industrial applications is its substantial gelating property. Fields of use are food technology, pharmaceutical and cosmetic industries, the photography industry and a number of technical industries. Attention is drawn to the fact that in recent literature gelose material obtained from Gracilaria has frequently been called Gracilaria Gum.
