how to make sodium alginate beads

Sodium Alginate (alginate algin)

Sodium Alginate is a natural polysaccharide product extracted from brown seaweed that grows in cold water regions In modernist cuisine sodium alginate is mostly used with calcium salts to produce small caviar-like and large spheres with liquid inside that burst in the mouth Sodium Alginate is also used in the food industry to increase viscosity and as an emulsifier

Preparation and Characterization of Biosorbents Beads

Calcium alginate beads are formed when sodium alginate salt is added dropwise to a fixing solution of calcium chloride Calcium alginate beads has been one of the most extensively investigated biopolymers for binding multivalent cations So it has been used for the removal of heavy metals from dilute aqueous solutions (Apel and Torma 1993)

Sodium alginate

Sodium Alginate is the sodium salt form of alginic acid and gum mainly extracted from the cell walls of brown algae with chelating activity Upon oral administration sodium alginate binds to and blocks the intestinal absorption of various radioactive isotopes such as radium Ra 226 (Ra-226) and strontium Sr 90

Basic or Direct Spherification

To produce Basic Spherification you need a solution with 0 5% sodium alginate (0 5 g per 100 g of flavored liquid) Sodium Alginate like most hydrocolloids needs to be dispersed in the liquid and hydrated before it can gel in presence of calcium ions This can simply be done by mixing the sodium alginate with an immersion blender or regular blender but you need to know a few
