Polyphosphoric acid (PPA) is a viscous, colorless liquid that is derived from phosphorus pentoxide. It has a wide range of applications in various industries, including the food sector.
In the food industry, PPA is used as a food additive and processing aid. It is often added to certain types of processed foods, such as baked goods, to improve their texture and shelf life. PPA can also be used as a flavor enhancer and as a preservative in certain types of food products.
In addition to its use as a food additive, PPA is also used in the production of certain types of food packaging materials. It is often added to plastics, such as polystyrene and polyethylene, to improve their strength and durability. PPA can also be used to modify the properties of paper and cardboard, making them more resistant to moisture and other environmental factors.
