Salt is a staple ingredient in every kitchen, and there are many different types of salt available.
One type that you may have heard of is kosher salt. But what exactly is kosher salt, and does it contain nitrates?
In this article, we will explore the properties of kosher salt and compare it to curing salt, which is commonly used in meat preservation.
We will also discuss the history of curing and the different methods used to preserve meat.
So, whether you are a home cook or a food enthusiast, read on to learn more about kosher salt and its role in food preservation.
Does Kosher Salt Have Nitrates?
Kosher salt is a pure form of sodium chloride, which means it does not contain any nitrates. This makes it a great alternative to curing salt, which is a mixture of sodium chloride and sodium nitrite.
Curing salt is commonly used in meat preservation to provide a longer storage life and alter the color and flavor of the meat. However, it is important to note that curing salt can be harmful if not used properly.
On the other hand, kosher salt is non-iodized and has a neutral salty taste. It was originally used by ancient Jews to preserve foods containing different kinds of meat. While it may not have the same preservative properties as curing salt, it can still be used in all kinds of food from veggies to meat.
It is important to note that if you are using kosher salt as a substitute for curing salt, you may need to add other elements for preserving the meat and to achieve the desired color. Meat cured without nitrite will be grey instead of the rosy pink and red color you want.
What Is Kosher Salt?
Kosher salt is a coarse-grained salt that is commonly used in cooking and food preparation. It gets its name from its use in the koshering process of meat, which involves drawing out the blood from the meat to make it fit for consumption according to Jewish dietary laws.
Unlike table salt, which is fine and heavily processed, kosher salt has a larger grain size and is less refined. This makes it easier to handle and control when seasoning food. It also has a milder flavor compared to table salt, which can be overpowering in dishes.
Kosher salt is made by compacting large crystals of salt together to form irregularly shaped flakes. This process gives it a unique texture that makes it ideal for seasoning meat and other foods. The larger flakes also make it easier to sprinkle over food evenly.
Kosher Salt Vs. Curing Salt
When it comes to choosing between kosher salt and curing salt, it is important to understand their differences and uses. Kosher salt is a coarse-grained edible salt that does not contain any nitrates. It is used primarily for seasoning and cooking, and it is a great alternative to table salt due to its pure form and neutral taste.
On the other hand, curing salt is a mixture of sodium chloride and sodium nitrite or sodium nitrate. It is used in meat preservation to prevent bacterial growth, enhance flavor, and improve the color of the meat. Curing salts are highly concentrated and should be used with caution.
While kosher salt can be used in all kinds of food, including meat, it may not have the same preservative properties as curing salt. If you are using kosher salt as a substitute for curing salt in meat preservation, you may need to add other elements such as sodium nitrite or sodium nitrate to achieve the desired color and preservation.
It is important to note that both kosher salt and curing salt have their own uses and benefits. While kosher salt is great for seasoning and cooking, curing salt is essential for meat preservation. It is important to use the right type of salt for each application and to always follow the recipe instructions carefully.
Understanding The Role Of Nitrates In Meat Preservation
Nitrates and nitrites are commonly used in meat preservation to prevent the growth of harmful bacteria such as Clostridium botulinum, which can cause serious illness when ingested. Nitrate is an inert salt that needs to be converted by bacteria into nitrite before it can be effective in meat preservation. Nitrite, on the other hand, is responsible for improving meat quality and safety.
When added to meat at the allowed levels set forth by the USDA, nitrite completely inhibits the growth of Clostridium botulinum and almost completely inhibits Clostridium perfringens. It also slows down the growth of other pathogenic bacteria such as Listeria monocytogenes. Due to these properties, nitrates and nitrites are classified as curing ingredients by the USDA.
The process of salting meat involves diffusion, which is the tendency for substances to disperse through another substance until equilibrium is reached. Salting includes the addition of nitrates and nitrites if used. These salts are responsible for the flavor, color, and safety of dry-cured meats. Salt prevents the growth of unwanted bacteria and aids in the drying of the meat.
While kosher salt does not contain any nitrates, it can still be used as a substitute for curing salt. However, it is important to note that if you are using kosher salt as a substitute for curing salt, you may need to add other elements for preserving the meat and achieving the desired color. Meat cured without nitrite will be grey instead of the rosy pink and red color desired in cured meats.
The History Of Meat Preservation
The history of meat preservation dates back to 3,000 BC when the Sumerians in Mesopotamia preserved cooked meats and fish in sesame oil and salt. Later, in 900 BC, the Greeks began producing salt gardens which were used for the drying and smoking of fish. By 200 BC, the Romans had learned how to use salt for preservation from the Greeks, and began preserving other kinds of meats including pork. During this time, the reddening effect of salt on meat was recorded.
As time passed, treating meat with salt, saltpeter, and smoke became common practice during medieval times. Saltpeter’s ability to fix the reddening of meat was recognized during this period. It wasn’t until the late nineteenth century that the role of nitrate and nitrite in color and flavor were recognized and meat curing became more of a science than an art.
By the end of the century, various methods of curing including dry, wet, or pickle cures and combinations were common. The meat packing industry began searching for ways to improve the quality of cured meats which resulted in scientific studies and knowledge. Since the mid-1920s, the meat curing industry has seen many advances. The direct use of nitrite was a huge advance as it greatly reduced the time required for curing.
Today, purified nitrate and nitrite are commercially manufactured for many uses from fertilizer to a variety of foods such as cured meats and toothpaste. Research has shown that nitrite salt is responsible for very effectively improving meat quality and safety. Nitrate salt is inert and must be first converted by bacteria to the form nitrite before it can be helpful for meat quality and safety.
Methods Of Meat Preservation
Meat preservation is the process of adding some combination of salt, sugar, nitrite and/or nitrate to meat for the purposes of preservation, flavor and color. There are different methods of meat preservation, including salting, corning or salt curing, dry curing, and wet or pickle curing.
Salting involves rubbing the cure ingredients onto the surface of the meat. Corning or salt curing involves packing the meat in a mixture of salt and other curing agents. Dry curing involves rubbing the cure ingredients onto the meat and then hanging it to dry. Wet or pickle curing involves submerging the meat in a brine solution until it is completely covered.
Curing salt is a toxic form of salt that always contains nitrites and sometimes nitrates. It is commonly used for meat preservation because it kills microbes in the food and provides a longer storage life. However, it should be used with caution and kept out of reach of children.
If you want to use regular salt for curing but still want nitrates for preserving, one solution is to use celery juice. The celery juice contains natural nitrates which will work similarly to saltpeter in curing. However, it’s not as effective as curing salt, so it’s best to follow recipes for curing instead of making up your own concoctions.

The Pros And Cons Of Using Kosher Salt In Meat Preservation
There are both pros and cons to using kosher salt in meat preservation.
One of the main advantages of using kosher salt is that it is a pure form of sodium chloride, without any additives or anti-caking agents. This means that it is a more natural and healthier option compared to other types of salt. Additionally, kosher salt has a larger crystal size compared to regular table salt, which makes it easier to control the amount of salt used in a recipe.
Another benefit of using kosher salt is that it does not have a strong flavor, which allows the natural taste of the meat to shine through. This can be particularly appealing for those who prefer a more subtle seasoning in their meat.
However, using kosher salt as a substitute for curing salt does have some drawbacks. As mentioned earlier, meat cured without nitrite will not have the same rosy pink and red color that is expected. This can be a concern for those who want their meat to look appetizing and visually appealing.
Furthermore, using kosher salt may require additional elements to preserve the meat and prevent bacterial growth. While it may work well for short-term preservation, it may not be as effective for long-term storage.
