PGA-Propylene Glycol Alginate The Best Sodium Alginate

Propylene Glycol Alginate is made by esterification of the carboxyl groups in alginic acid with propylene glycol groups. It is soluble in both cold and hot water and forms smooth and viscous solutions.

Propylene Glycol Alginate (PGA) can be used in such areas where sodium alginate does not work.?
PGA becomes an acidic aqueous solution when dissolved in water. It can be dissolved even in acidic foods, resulting in thickening and stabilizing effects.
Due to masking by the propylene glycol group, the carboxyl group does not dissociate in water making it difficult to crosslink even in the presence of calcium ions, and therefore PGA can be effectively used as a stabilizer for dairy products and in similar applications.
In addition, PGA has a lipophilic propylene glycol group added to hydrophilic alginic acid giving a surface-active effect not found in other alginates.
