1.What is Potassium Sorbate Granular ?

Potassium Sorbate Granular (PSG) is the potassium salt of Sorbic Acid. It appears as a white to off-white granular. This product is often used as a food preservative for a variety of applications including food and wine. It is used to inhibit molds and yeasts in many foods, such as cheese, wine, yogurt, dried meats, apple cider, soft drinks, fruit drinks, and baked goods. It can also be used in dried fruit products.

2.How is Potassium Sorbate Granular produced?

The main component of potassium Sorbate, sorbic acid, occurs naturally as para-sorbic acid in berries of the mountain ash tree. However, it is often synthesized by various processes. This can include, for example, condensing crotonaldehyde and acetic or malonic acid in pyridine solution, condensing crotonaldehyde and ketene in the presence of boron trifluoride, and other processes. Potassium Sorbate is manufactured by reacting sorbic acid with an equimolar portion of potassium hydroxide. The manufacturer then crystallizes the resulting potassium Sorbate from aqueous ethanol.

3.What Does Potassium Sorbate Do in Our products?

Potassium Sorbate is a preservative; it keeps microorganisms from growing. It is a common ingredient in cheese, baked goods, juice, produce, wine, soda, pickled products and some protein products. Potassium Sorbate in also present in thousands of personal care products, including shampoo, conditioner, body wash, moisturizers, makeup, sunscreen and other items. It dissolves in alcohol and slightly in water.

4.What is Potassium Sorbate Granular used for?

Potassium sorbate is a preservative used in different types of packaged foods to prevent them from being spoiled by microorganisms, namely fungi (such as mold) and certain bacteria. It's also classified as a food additive. "Potassium sorbate is used to help make food safe by curbing microbial growth," says Isabel Maples, MEd, RDN, a spokesperson for the Academy of Nutrition and Dietetics. "It's there to help extend shelf life [of packaged food]."
