Calcium alginate

Calcium alginate is a water-insoluble gelatinous cream-coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate Calcium alginate is also used for entrapment of enzymes and forming artificial seeds in plant tissue culture Alginate is usually the salts of alginic acid but it can also refer to derivatives of alginic acid

Production of Alginate Beads

The chemical reaction between sodium alginate and calcium ions is dependent upon the solubility and availability of calcium ions Some calcium salts (e g CaCl 2 calcium lactate) were readily soluble and fully dissociated in water and resulted in an immediate gelation of the alginate Dicalcium phosphate (DCP) was sparingly soluble at pH 7 and calcium ions were

Spherification and Edible Water Spheres

When sodium alginate (dissolved in a liquid) meets calcium chloride (dissolved in water) a chemical reaction happens! Just like when oil is mixed with water little spheres start to form in the solution trapping the liquid inside It only takes a few seconds for the calcium solution to cause the outer layer of the alginate liquid to form a thin and flexible skin
