Abstract

Procyanidin hydrogels suitable for antacid therapy were developed from alginates with antipeptic properties. The influence of calcium ion on the gelling of colloidal solutions of sodium and potassium alginates was studied. Calcium gluconate displayed a marked reticulating ability, accentuating the pseudoplasticity and reducing the limpidity of the colloids.
