Propylene glycol alginate, also known as propylene glycol alginate (PGA), is made from the deep processing of alginic acid extracted from natural algae. Compared with alginate, it has stronger acid and salt tolerance and is an excellent marine food additives.
Product Description
Propylene Glycol Alginate is an ester of alginic acid, which is derived from kelp. It is white to yellowish brown filamentous, grainy, and can be in both granular and powdered forms.
PGA is known as an emulsifier, stabilizer, and thickener used in food industry.
