Prague Powder Can Take Your Curing Process to the Next Level

D.Q. Pink Curing Salts
D.Q. Pink Curing Salts

Prague powder No. 1 is a curing mixture that the federal government mandates be composed of 6.25 percent sodium nitrite and 93.75 percent table salt (sodium chloride). It's used in making cured meat products such as sausages, including hot dogs, fish, and corned beef.

So Prague powder No. 1 is mostly salt. And the way salt works as a preservative is through a process called osmosis, which describes what happens when the water within a cell is drawn out through the cell walls.

Food spoilage and food poisoning are caused by single-celled organisms called bacteria. Salt pulls out the water from within the bacteria cells, killing them. Sugar does the same thing, which is why foods with high amounts of salt or sugar are among those that often don't require refrigeration.

Its second ingredient, sodium nitrite, is a natural compound found in vegetables such as carrots and spinach because of the compound's prevalence in soil (nitrogen being 78 percent of our atmosphere). Sodium nitrite is known to prevent the growth of bacteria, and is also an effective anti-toxin and considered an essential medicine by the World Health Organization.

Combined, table salt mixed with sodium nitrite form a highly effective food preservative, which also has antimicrobial properties. The pink coloring is added so that it won't be mistaken for ordinary salt.

Adding Color

Prague powder is responsible for producing the pink color in cured meats.

It does this by interacting with a component of the protein in meat called heme, which is the part of a red blood cell that gives blood its color.

Why Is It Called 'Prague,' Anyway?

It's called Prague powder, or sometimes Prague salt, because the process for adding sodium nitrite to meat for the purpose of curing it was first developed in that city when it was part of the Habsburg Empire.

One teaspoon of Prague powder mixed with cold water will cure about 5 pounds of meat.

Another special property of Prague powder No. 1 is that it prevents the growth of the deadly Clostridium botulinum bacteria, which causes botulism.

Know Your Numbers

Prague powder No. 1 is not to be confused with Prague powder No. 2, which is used in making dry-cured meats, including hard salami, pepperoni, and prosciutto.

Prague powder No. 1 is only meant to be used in very small quantities. That's why it's colored pink to prevent it from being mistaken for ordinary salt. Accidentally adding Prague powder No. 1  to food like normal salt wouldn't be good for you.
