Gelrite is a naturally-derived gelling polymer that can be used in a variety of applications as a solidification agent instead of agar. Produced by microbial fermentation; Gelrite is a highly purified natural anionic polysaccharide without the variations commonly associated with agar. Gelrite forms rigid; brittle; agar like gels at approximately half the use level of agar in presence of soluble salts like Mg2+ and Ca2+. Gels prepared with Gelrite- are remarkably clear in comparison to those formed with agar. Gelrite contains no contaminating matters (e.g.; phenolic com-pounds) as found in agar that are toxic to certain sensitive organisms.Li-Chun Huang; Toshio Murashige et al.
