SODIUM NITRATE / SALTPETRE

SODIUM NITRATE (SALTPETRE) - A TRUSTED PRESERVATIVE FOR CURED MEATS AND CHEESE

Saltpetre,
also know as Sodium Nitrate (NaNO3), is a well established preservative used in the production of cured meats and selected cheese varieties to prevent undesirable microbial activity and quality defects. Its controlled use helps ensure product safety, stability, and consistent quality throughout storage and ripening.

What is Saltpetre?
Sodium Nitrate is a white, crystalline, slightly hygroscopic inorganic salt that has been used for centuries in traditional food preservation. In curing and cheesemaking, it functions primarily in traditional food preservation. In curing and cheesemaking, it functions primarily by inhibiting spore-forming and gas-producing bacteria, helping to prevent spoilage, off-flavours, and structural defects.

Used in Cured Meat
In cured meat applications such as bacon, ham, and sausages, Sodium Nitrate is typically used as part of a curing system together with salt, sugar, and/or Sodium Nitrite. During curing and storage, nitrate is slowly reduced to nitrite, providing long-term protection against harmful bacteria, including Clostridium botulinum, while supporting colour stability and characteristic cured flavour.

Role In Cheesemaking
In semi-hard and hard cheeses – Sodium Nitrate is added to cheese milk to prevent late blowing defects caused by gas-producing Clostridia and certain coliform bacteria. Its use helps maintain proper texture, flavour development, and structural integrity during ripening.

How to Use
Sodium Nitrate is normally:
• Dissolved in water and added to cheese milk (general up to 200 g per 1 000 l / Gouda & Edam ± 100 g per 1 000 L), or
• Included as part of a formulated curing mix for meats.
Controlled dosing is essential, as overuse may inhibit starter cultures, slow ripening, or cause flavour and colour defects.

Sodium Nitrate offers proven, dependable preservation for traditional and industrial meat curing and cheese production when used responsibly and according to guidelines.
