Propylene Glycol Alginate (PGA)

CAS No.9005-37-2
Molecular Weight: 234.21
Appearance: White Powder
Purity: 99%

Function
1. In the food industry, it is used as a thickener, emulsifier and stabilizer.
2. Propylene glycol alginate has strong acid resistance and can be used in acidic environments with a pH of 3-5.
3. Propylene glycol alginate has good foaming and emulsifying ability, and is widely used in yogurt products, seasonings and beer foam stabilizers.
4. Propylene glycol alginate has the characteristics of hydration, anti-aging and tissue improvement. It is suitable for raw dry noodles, raw wet noodles, instant rice noodles, frozen rice noodles, bread, pastries and other baked foods.

Application
1. Application in bakery products:
Propylene glycol alginate can improve the water absorption, elasticity and water retention of the dough, and improve the taste of the product.
2. Application in cake:
Propylene glycol alginate can improve the water absorption of dough, improve the water retention of baked products, and make the products soft and dry.
3. Application in flour products:
Propylene glycol alginate can significantly improve the water absorption and stability of dough, and strengthen gluten for noodle products. And because of its good emulsification and thickening properties, it is especially suitable for some flour products to reduce the oil absorption rate of flour products and reduce the phenomenon of oil rancidity.
4. Application in yogurt:
Propylene glycol alginate can produce more excellent taste and stability, and can effectively prevent the product from forming an unsightly rough concave-convex surface, making the appearance of the product smooth and shiny.
5. Application in acidic milk beverage:
Propylene glycol alginate can stabilize protein, emulsify fat, improve taste and protect aroma.
6. Application in fruit juice:
Propylene glycol alginate can improve the stability of the pulp, make the juice thicker and taste better, maintain the flavor substances of the juice, and keep the juice fragrance strong and refreshing.
7. Application in salad dressing:
Propylene glycol alginate can act as a stabilizer and emulsifier. It can not only provide a pleasant texture of salad dressing, but also provide double emulsification stability and stabilize the suspension of solid particles. Of course, it also has a certain thickening effect. It also provides fat-like properties in low-fat salad dressings.
8. Application in ice cream:
Propylene glycol alginate can significantly improve the dispersion of oil and fat-containing solid particles and the taste, internal structure and appearance of ice cream, and can also improve the dispersion stability and melting resistance of ice cream. In addition, propylene glycol alginate can also prevent the formation of lactose ice crystals in ice cream.
9. Application in beer:
Propylene glycol alginate prevents the resulting foam collapse. The foam retention of the beer added with propylene glycol alginate is obviously improved, the foam is white and fine, and the hanging cup lasts for a long time, while the taste and storage period of the beer will not change.

Description About Propylene Glycol Alginate (PGA)
Propylene glycol alginate is a new type of emulsifier. It is a polysaccharide biopolymer synthesized by esterification of alginic acid extracted from brown algae. It is generally white or yellowish white fine powder, odorless or has a slight aroma of aromatic hydrocarbons.
It is made of alginic acid extracted from natural seaweed. The appearance is white or light yellow powder, and it becomes a viscous colloid after being dissolved in water. It is often used as a thickening, stabilizing and emulsifying agent for beverage products.
Propylene glycol alginate is a marine food additive with excellent performance. It has good thickening, puffing, acid resistance and foam stability. It has been widely used in food processing, yogurt products, seasoning and beer and other fields. Through the esterification reaction of alginic acid and propylene glycol, the hydroxyl group can be transformed into a less active ester group. The propylene glycol alginate produced by catalysis, pressurization and other processes has good acid and salt resistance, is soluble in water, and forms a viscous colloidal solution, insoluble in organic solvents such as ethanol.
Propylene glycol alginate can be used in the manufacture of thickeners, stabilizers, gelling agents, emulsifiers and water-holding agents.
