Sodium acid pyrophosphate is also used in the preservation of color and freshness, especially in cut potatoes and other vegetables. Its ability to act as an antioxidant helps to prevent enzymatic browning, thus maintaining an appealing appearance and flavor.

This could lead to increased cravings and consumption, leading some to argue that MSG could have addictive properties.
