Hot sauce has been made with vinegar since it originally became a spicy condiment almost 200 years ago. Manufacturers are reaching for new hot sauce recipes which exclude the use of vinegar as a preserving ingredient. Other preservatives are being used and added to hot sauce recipes to extend the shelf life, keep them safe for consumers and allow them to stay fresher longer.
The best preservatives for hot sauce are citric acid, potassium sorbate, ascorbic acid, acetic acid, and sodium benzoate. These additives will preserve a hot sauce, extend the shelf life and keep it fresh longer without altering the flavor, aroma or consistency of a hot sauce recipe.

To use citric acid as a preservative, you can follow these steps:
Determine the appropriate concentration
Citric acid can be used as a preservative in various concentrations depending on the specific application. The concentration will vary depending on the type of food or product you want to preserve. It’s important to consult reliable sources or guidelines to determine the appropriate concentration for your specific use.
The amount of citric acid needed in a recipe can vary depending on factors such as the specific recipe, desired acidity level, and taste preferences. Citric acid is typically used in small quantities as a flavor enhancer and acidifier.
To determine the amount of citric acid to use in a recipe, you can start with a small quantity and adjust to taste. As a general guideline, a common starting point is to use about 1/4 to 1/2 teaspoon of citric acid per 1 cup (240 ml) of hot sauce or per 1 kilogram of food product.
It’s important to note that citric acid is highly concentrated, so a little goes a long way. It’s always recommended to start with a smaller amount and gradually increase if needed, tasting as you go to achieve the desired level of acidity and flavor.
Additionally, it’s important to consider any specific recipe instructions or guidelines that may recommend a different amount of citric acid. Some recipes may have specific requirements or ratios to maintain the desired balance of flavors.

If you’re unsure about the appropriate amount of citric acid to use in your specific recipe, it’s always a good idea to consult reliable sources, recipe guidelines, or consult with a food expert for more precise recommendations. Many Hot Sauce Co-Packers can provide this information for you.
Prepare a citric acid solution
Dissolve the citric acid powder in water or the liquid you are using in your hot sauce recipe to create a solution. The concentration of the solution will depend on the desired concentration of citric acid as a preservative. Make sure to use clean, filtered water to avoid any contaminants.
Add the citric acid solution to the product
Once you have prepared the citric acid solution, you can add it to the product you want to preserve. The method of addition will depend on the specific product. For example, if you are preserving fruits or vegetables, you can either dip them in the citric acid solution or spray the solution on them. If you are preserving a liquid product, you can simply add the citric acid solution directly to it.
Mix thoroughly
Ensure that the citric acid solution is evenly distributed throughout the product. This will help in preserving the entire batch uniformly. Adding the citric acid solution before the blending process will ensure this step is completed properly.
Seal and store
After adding the citric acid solution, make sure to seal the product properly to prevent contamination. Store the product in appropriate conditions, such as refrigeration or a cool, dry place, depending on the specific requirements of the product.
Citric acid may not be suitable for all types of preservation. It is primarily effective in inhibiting the growth of certain bacteria and fungi.

Determine the appropriate concentration
To determine the amount of potassium sorbate to use in a recipe, you can start with a recommended concentration range and adjust accordingly. As a general guideline, a common starting point is to use about 0.1% to 0.2% of the total weight of the product.
The amount of potassium sorbate needed in a recipe can vary depending on factors such as the specific recipe, desired preservation effects, and regulatory guidelines. Potassium sorbate is typically used as a preservative in small quantities.
Here’s an example to illustrate the calculation:
- Determine the total weight of the product: Let’s say your recipe yields 1 kilogram (1000 grams) of hot sauce.
- Calculate the amount of potassium sorbate: If you want to use a concentration of 0.1% to 0.2%, you would multiply the total weight of the product by the desired percentage. For example:
- 0.1% of 1000 grams = 1 gram of potassium sorbate
- 0.2% of 1000 grams = 2 grams of potassium sorbate
These calculations are based on weight, so if you’re using a different unit of measurement, you’ll need to convert accordingly. Always follow recommended guidelines and consult with reliable sources or regulatory bodies for specific recommendations on the use of potassium sorbate as a preservative. It’s also important to handle and measure potassium sorbate accurately, following proper safety precautions.

How to measure preservation in a hot sauce recipe
Measuring preservation in a hot sauce recipe typically involves assessing factors such as pH level, water activity (aw), and the use of preservatives. Here are some steps to consider when measuring preservation in a hot sauce recipe:
pH level
Measure the pH level of your hot sauce using a pH meter or pH test strips. The pH level is an important factor in determining the acidity of the hot sauce, which can affect the growth of microorganisms. Generally, a pH level below 4.6 is considered safe for … preventing the growth of most bacteria. However, specific pH requirements may vary depending on the recipe and desired shelf life.
Water activity (aw)
Water activity refers to the amount of available water in a product that is accessible to microorganisms. It is measured on a scale from 0 to 1, with lower values indicating lower water activity and reduced microbial growth. While measuring water activity may not be practical for … home cooks, it is an important consideration for commercial producers. Ensuring a low water activity level can help enhance the preservation of the hot sauce.
Preservatives
If you are using preservatives such as citric acid, potassium sorbate, or sodium benzoate, it’s important to measure and use them in the appropriate concentrations. Follow the recommended guidelines or regulatory requirements for the specific preservative you are using. This will help inhibit the growth of microorganisms and extend the shelf life … of the hot sauce.
Microbiological testing
If you are producing hot sauce on a larger scale or for commercial purposes, it may be necessary to conduct microbiological testing to assess the effectiveness of preservation.
