[Description]:
Propylene Glycol Alginate is of white powder and it is easy to dissolved in water and its
water solution become gel. Propylene Glycol
Alginate (PGA) is an ester of alginic acid in which originally derived
from brown algae as some of the carboxyl groups are esterified with propylene glycol, some
neutralized with an appropriate alkali and some remain free. It is in the form of white or
flaxen powder and can be easy dissolved in water.
[Applications]:
Food industry
