Utilization of High Hydrostatic Pressure to Make Alginate Gels

Alginate gel formation under high hydrostatic pressure was studied. Sodium alginate was mixed with various calcium salts and water was added to make slurry. An hydrostatic pressure of 900 MPa was applied. Calcium salts with different solubility were used, i.e. calcium chloride, calcium citrate, calcium lactate, calcium gluconate, and calcium carbonate
