Description
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.
