Food additives propylene glycol alginate
1.Introduction:
Propylene glycol alginate (abbreviated as PGA), is derived from alginic acid which is extracted
from natural seaweed. It is in the form of white or flaxen powder. Aqueous solution is viscous
colloid. Compared with alginate , it has better resistance against acid and salts. And PGA is a good
seaweed based food additive which has excellent performance.

3. Applications:
PGA is an excellent food additive derieved from algae, and can be widely used in both food and pharmaceutical field due to its unique properties.
Besides the thickening function, PGA is also a surfactant due to the amphiphilic structure. PGA doesn't form a gel with polyvalent metal, therefore, it is stable with metal.
1. In Food Application:
1) as a thickener, stabilizer and emulsifier in yogurt and ice cream, the addition of PGA can make the product soomth and improve the mouthfeel;
2) as a stabilizer and emulsifier in cheese, PGA makes cheese puffing and emulsifying well, the mouthfeel is smooth;
3) as a foam stabilizer in beer, PGA can improve and maintain the foam levels;
4) as a dispersant and emulsifier, PGA is acid stable, therefore, it canbe used in all kinds of fruit juice, which can keep the beverage uniform;
5) as texture improver, PGA can be used in flour, noodles and instant foods;
6) furthermore, PGA can be also used in ketchup, sauce, syrup, etc.
2. In Pharmaceutical Application:
PGA can be used as a stabilizer for X-ray contrast agent, a protective agent for gastrointestinal mucosa, and a raw material for cosmetics.
