Potassium Nitrate, (Saltpeter), 2.5kg, Food Grade

Our food grade Potassium Nitrate, also known as saltpeter, is a historical curing agent used in the production of cured meats and charcuterie. It plays a few key roles in the curing process:

• Color preservation: Potassium nitrate helps prevent the cured meat from losing its pink color and turning a grayish-brown.
• Flavor development: It contributes to the characteristic savory flavor of cured meats.
• Antibacterial properties: While not as effective as some other curing agents, potassium nitrate does have some antibacterial properties that can help extend the shelf life of cured meats.

Other uses for it are in pyrotechnics, rocket ignition compounds, incense manufacture, and tree stump remover. It is one of the three components of black powder, along with powdered charcoal (substantially carbon) and sulfur, where it acts as an oxidizer. Commercial uses include specialty fertilizer, glass manufacturing, and tempering steel.

For shipping, Potassium Nitrate is in hazardous materials Class 5: Oxidizer. It only ships to destinations within the 48 contiguous US states using Standard Ground. A HazMat fee applies to this 2.5kg size. Adult signature required upon delivery. Shipping to a commercial address is suggested.

For less shipping restrictions, our smaller 500g size may be shipped to Canada and has no HazMat fee.
