Potassium Sorbate

Sorbic Acid occurs naturally in the Rowanberries and the berries of the mountain ash in the form of Parasorbic Acid. This was discovered in 1895 and later chemically synthesized in 1900. The ANTIMYCOTIC and ANTIBACTERIAL actions were verified in 1945 and since then SORBIC ACID and POTASSIUM SORBATE have been recommended as an effective preservative for the protection of food products.

In the United States of America, Japan and Europe and almost all of the other countries of the world POTASSIUM SORBATE is a legally permitted preservative because of its outstanding physiological properties.

Innumerable tons of foodstuffs are saved each year from perishing because of the use of Potassium Sorbate as a preservative method.

The application of Potassium Sorbate becomes continually more important because of its effectiveness in combating microorganisms that attack foodstuffs.

Because Potassium Sorbate metabolizes like a food fatty acid, it is harmless to the human organism. If it is used in the correct amounts Potassium Sorbate do not affect the taste or smell of foodstuffs.

Potassium Sorbate is a preservative that attacks certain bacteria, molds and yeast.

Minimum concentrations of preservatives are determined by the pH and the water content of the foodstuffs to be preserved. The lower the pH value of the product the higher the acid and thus a lower amount Potassium Sorbate is needed for preservation.

Of course, Potassium Sorbate can only protect product from attack by mold, yeast and bacteria if the food product has been processed under hygienic conditions. Already infected or partially perished food products cannot be protected through the addition of Potassium Sorbate. Potassium Sorbate is a mold inhibitors. It inhibits mold from growing. It does not kill already established mold.

If food products are to be boiled intensively for long periods of time, it is recommended to add Potassium Sorbate after the process to avoid its partial escape through evaporation of the water.

A basic idea to keep in mind when contemplating uses for Sorbic Acid or Potassium Sorbate is that Potassium Sorbate is water soluble and Sorbic Acid is soluble in fats, oils and some solvents but virtually insoluble in water.

Sorbic Acid is the active ingredient in both Sorbic Acid and Potassium Sorbate and although different rates could be used in a finished product, the results would be the same.

Potassium Sorbate is considered by the Food and Drug Administration to be "generally recognized as safe" (GRAS); therefore, the only limitations on their use is that the quantity not exceed the amount reasonably required to accomplish the desired preservative function. Food standards must also be consulted as they list the certain foods official specifications for certain standardized foods. In this case, only those ingredients listed in the standard and their respective amounts can be used.

GRAS chemicals can be used at any safe, suitable and reasonable levels in unstandardized foods to accomplish their functions.

State laws should be consulted which may differ from Federal regulations.

In all cases, when Potassium Sorbate is used in a product, it must so state on the label.

BAKERY PRODUCTS

Most bakery products due to their high moisture and sugar content are subject to rapid mold growth and spoilage. Potassium Sorbate can extend the shelf life of various baked goods: Breads cakes, doughnut mixes, fillings, doughs, muffins, tortillas, etc.

Generally either product is added to the dough at rates of .03% to .3% per 100 weight of batter.

A topical spray of Potassium Sorbate has been used on bread, muffins and tortillas to prevent surface mold growth. In doughs that are yeast leavened generally Potassium Sorbate is not used as it has a strong inhibitory action on fermentation.

In fruit fillings as well as icings and cream fillings that are used in bakery products, Potassium Sorbate has been proven to be most effective at levels of .03% to 0.1% batter weight.

PHYSICAL PROPERTIES

Potassium Sorbate is a practically odorless white powder that is also available in a dust free granule.

STORAGE

Potassium Sorbate must be protected from excessive light and heat. Because Potassium Sorbate is water soluble, it must remain dry during storage. Containers should always be closed after use.
