How to use potassium sorbate?

You can use potassium sorbate in the following ways:

To inhibit yeast growth. Potassium sorbate is used in many foods as a preservative. It inhibits mold and yeast growth, making it useful for keeping foods such as jams, jellies, syrups, and other products from spoiling.

As an antioxidant preservative. Potassium sorbate can also be used to prevent oxidation of fats in food products. This is particularly important for seafoods such as tuna steaks or salmon fillets that have been marinated with oil or lemon juice and then cooked in the same oil or juices. If you add potassium sorbate to these marinades before cooking them, you can prevent oxidation of the fat in the fish so that it remains bright red after cooking.

In cheese making. Potassium sorbate is added to cheesemaking mixtures during fermentation to prevent bacteria from growing on the surface of the cheese curd during aging (see How Cheese Is Made).

How does potassium sorbate work?

Potassium sorbate inhibits the growth of mold and yeast by stopping the enzyme oxidase from functioning properly. This enzyme is needed for respiration, which is necessary for life. Without it, no fermentation can occur, so mold or yeast will not grow in a product containing potassium sorbate.

How is potassium sorbate made?

By neutralizing sorbic acid with potassium hydroxide, it can be manufactured commercially by neutralizing other food preservatives such as E200 (a naturally occurring food preservative that can be found in berries).

The manufacturing process can be summarized in four steps:

  1. By condensation of ketene and crotonaldehyde, 3-hydroxy-4-hexenoic acid polymeric ester is obtained. A reaction equation is as follows: H2C=C=O + CH3–CH=CH–CHO = CH3CH=CH−CH=CH−COOH
  2. Decomposition: Sorbic acid is produced as a result of the decomposition of the polyester.
  3. Purification: It can be accomplished by activating carbon, distilling, recrystallizing, or any combination thereof.
  4. Potassium hydroxide neutralization.

Potassium sorbate specification

Potassium sorbate properties

Appearance

With a neutral taste and odor, this powder is crystal white, granular, or spherical. If exposed to humid air, it absorbs water easily and expires.

Potassium sorbate structure

Solubility

Water and ethanol are freely soluble. It is usually made into its water-soluble potassium salt – potassium sorbate (solubility 67.6g/100ml at 20 °C) as a preservative in food due to its low water solubility (0.16g/100ml at 20 °C).

PH

The antimicrobial activity of this substance is best under acidic conditions with a pH value of less than 5-6 and in a wide range of pH from 3.0 to 6.5. As the pH decreases, the activity increases.

In contrast, sodium benzoate and potassium benzoate almost lost their antimicrobial activity in the presence of a higher pH range, whereas potassium benzoate will still be effective at PH 6.5, while sodium benzoate cannot be used in the presence of higher pH ranges. It is important to note, however, that potassium sorbate will also be ineffective at pH levels above 7.0.

What’s the application of potassium sorbate?

A variety of microorganisms are protected by using sodium benzoate and potassium sorbate together in acidic foods. Microorganisms such as mold, yeast, and other microbes cannot grow in potassium sorbate, which prolongs food preservation.

Depending on PH, microbial types, and other factors, preservation dosages range from 250 ppm to 1000 ppm.

Use it directly, spray it, add it to packing materials, etc.

Soft Drink

Diet soft drinks often contain potassium sorbate as a preservative.

Coca Cola

In addition to sodium and potassium benzoate, potassium sorbate is also commonly used as a preservative in some non-carbonated and juice-containing drinks used by Coca-Cola to protect the flavor of the beverage. It can be found in ingredients lists for Sprite Limeade and Fanta Orange as well.

Pepsico

Pig, poultry, cat, and dog food can also be safely preserved with it.

Is potassium sorbate safe to use?

Yes, it’s safe to use potassium sorbate in food. The Food and Drug Administration (FDA) has approved it as a food additive and listed it as “generally recognized as safe” (GRAS). It can be used in all kinds of foods, including baked goods, dairy products, fruit juices, jams and jellies, and canned fish.

Metabolism

In the human body, potassium sorbate is metabolized into water and CO2 after participating in fat metabolism.

FDA

Chemical preservatives that are used in accordance with good manufacturing practices are generally recognized as safe (GRAS).

How much to use

Potassium Sorbate vs Sodium Benzoate

Sodium benzoate is a widely used preservative in food and beverages. It has been used for years because it’s cheap, effective, and safe. However, there are new concerns about sodium benzoate as a preservative for food products.
