Sodium hydroxide solid

Sodium hydroxide is a strong base (pH >14), and therefore very cost-effecive and is used at very low levels. It is used to neutralise acid and in the hydrolysis of proteins.

Sodium hydroxide is available as both a solid (pellets of flakes) and a concentrated liquid, both of which are very caustic, and precautions need to be taken to avoid these materials coming into contact with the skin. Once diluted in the food it is harmless.

Food uses of sodium hydroxide include washing or chemical peeling of fruits and vegetables, chocolate and cocoa processing, caramel coloring production, soft drink processing, and thickening ice cream. Olives are often soaked in sodium hydroxide for softening; Pretzels and German lye rolls are glazed with a sodium hydroxide solution before baking to make them crisp and dark brown.

The sodium hydroxide pellets are available in 100gr, 250gr and 1kg.
