Is Canning Salt The Same As Citric Acid? (Fully Explained)

Are you confused about the difference between canning salt and citric acid?

Do you wonder if they can be used interchangeably in your home food preservation recipes?

Look no further!

In this article, we’ll explore the characteristics of these two ingredients and help you understand how they can be used in your canning and pickling endeavors.

Whether you’re a seasoned home chef or just starting out, this information will be valuable to you.

So sit back, relax, and let’s dive into the world of canning salt and citric acid.

Is Canning Salt The Same As Citric Acid?

The short answer is no, canning salt and citric acid are not the same thing.

Canning salt, also known as pickling salt, is pure salt without any additives like iodine or anti-caking agents. It is the best choice for canning, pickling, and making sauerkraut. Its coarse texture makes it ideal for preserving vegetables and fruits by drawing out moisture and inhibiting the growth of bacteria.

On the other hand, citric acid is a form of acid that can be added to canned foods to increase their acidity. This is particularly important for low-acid foods like tomatoes, which are highly prone to botulism if not properly preserved. Citric acid can also improve the flavor and color of canned foods.

While both canning salt and citric acid are used in home food preservation, they serve different purposes. Canning salt helps to preserve the texture and flavor of vegetables and fruits, while citric acid helps to prevent spoilage and improve taste.

What Is Canning Salt?

Canning salt, also known as pickling salt or preserving salt, is a type of salt that is specifically designed for use in food preservation. It is made of pure sodium chloride and does not contain any additives like iodine or anti-caking agents, which are commonly found in regular table salt.

The purity and fine-grain texture of canning salt make it ideal for pickling vegetables and preserving other foods. Its ability to dissolve easily in water also makes it perfect for creating brines. The absence of additives ensures that the brine remains clear and does not darken the color of pickled vegetables.

Canning salt is also preferred by many home chefs because of its ability to preserve the texture and flavor of fruits and vegetables. It draws out moisture from the food, inhibiting bacterial growth and preventing spoilage.

What Is Citric Acid?

Citric acid is a concentrated powder that is commonly used in both home cooking and the food industry to prevent food spoilage in home-canned goods. It is often preferred over lemon juice because it does not interfere with the flavor of tomatoes as much as lemon juice does. Citric acid also prevents browning in peeled and diced fruit, making it a useful natural ingredient for cooking or canning. Manufacturers derive citric acid by drying and grinding citrus fruits like limes and lemons. The final texture of citric acid depends on its intended use, with some products coming in powder form for candy making, while others are specified as “crystalline citric acid” for use in canning instructions. While the terms citric acid and sour salt are essentially interchangeable, it is important to consult a doctor for specific instructions if you need citric acid for a medical condition, as the form of citric acid needed may differ from that offered for food use. Overall, citric acid is an essential ingredient for maintaining safe pH levels in canned foods and improving their flavor and color.

Differences Between Canning Salt And Citric Acid

There are several key differences between canning salt and citric acid. Firstly, canning salt is pure sodium chloride without any additives, while citric acid is a form of acid that is added to canned foods to increase their acidity. Secondly, canning salt is primarily used to preserve the texture and flavor of vegetables and fruits, while citric acid is used to prevent spoilage and improve the taste of low-acid foods.

Another difference between the two is their texture. Canning salt has a coarse texture that makes it ideal for preserving vegetables and fruits by drawing out moisture and inhibiting the growth of bacteria. Citric acid, on the other hand, comes in either a coarse granular crystal form or a more finely ground crystalline powder form. When ready for home canning use, it looks like finely granulated sugar or table salt.

It is important to note that while both canning salt and citric acid are used in home food preservation, they cannot be used interchangeably. Canning salt should not be used to increase the acidity of low-acid foods like tomatoes, as it does not have the same effect as citric acid. Similarly, citric acid should not be used as a substitute for canning salt in preserving vegetables and fruits.

How To Use Canning Salt In Canning And Pickling

When it comes to using canning salt in canning and pickling, it’s important to note that it’s not recommended to substitute other types of salt for pickling salt. However, in a pinch, kosher salt or sea salt can be used as a substitute. These salts are more likely to be additive-free and can be used with a measurement conversion to ensure the correct amount of salt is added to the pickle brine.

To use canning salt in canning and pickling, simply add the required amount of salt to the recipe. It’s important to note that different types of salts have different grain sizes, which can make accurate measuring a challenge. For example, one cup of fine-grain pickling salt will contain more salt by volume than one cup of a coarse-grain salt. Therefore, it’s important to use the correct type of salt as specified in the recipe.

When it comes to pickling vegetables, canning salt is essential for drawing out moisture and inhibiting the growth of bacteria. It’s recommended to use 1-2 tablespoons of canning salt per quart of water when making a brine for pickling vegetables.

How To Use Citric Acid In Canning And Pickling

When canning or pickling low-acid foods like tomatoes, it’s important to add citric acid to increase their acidity and prevent the growth of bacteria, particularly botulism. To use citric acid in canning and pickling, follow these steps:

1. Select only disease-free, preferably vine-ripened, firm fruit for canning. Avoid using tomatoes from dead or frost-killed vines.

2. To ensure safe acidity in whole, crushed or juiced tomatoes, add 2 tablespoons of bottled lemon juice or 1/2 teaspoon of citric acid per quart of tomatoes. For pints, use 1 tablespoon of bottled lemon juice or 1/4 teaspoon of citric acid.

3. Acid can be added directly to the jars before filling with product. Add sugar to offset the taste if desired.

4. Four tablespoons of a 5 percent acidity vinegar per quart can be used instead of lemon juice or citric acid. However, vinegar may cause undesirable flavor changes.

5. If a procedure from the USDA Complete Guide to Home Canning for canning tomatoes offers both boiling water and pressure canning options, all steps in the preparation (“Procedure”) are still required even if the pressure processing option is chosen. This includes acidification.

6. Remember that citric acid is not a substitute for proper canning techniques and should be used in conjunction with other safe food preservation practices.

By following these guidelines, you can safely use citric acid in your home canning and pickling projects to improve acidity and prevent spoilage.

When To Use Canning Salt Vs. Citric Acid

When it comes to deciding whether to use canning salt or citric acid in home food preservation, it’s important to consider the type of food being canned. Canning salt is best for preserving vegetables and fruits with a high water content, such as cucumbers for pickles or green beans. It helps to draw out excess moisture and preserve the texture and flavor of the food.

Citric acid, on the other hand, is recommended for low-acid foods like tomatoes. Adding citric acid to canned tomatoes can increase their acidity and prevent the growth of harmful bacteria that can cause botulism. Citric acid can also be used to improve the color and flavor of canned fruits and vegetables.

It’s important to note that citric acid should never be used as a substitute for vinegar or lemon juice in canning recipes. These acidic liquids are necessary for safe preservation and should not be replaced with citric acid.

In general, it’s best to follow a trusted canning recipe that specifies the appropriate type and amount of acid to use. If you’re unsure whether to use canning salt or citric acid, consult a reputable source like the USDA’s Complete Guide to Home Canning or a local extension office for guidance.
