Potassium Sorbate Uses

Potassium sorbate is mainly utilized as a food chemical, in addition to aesthetic antiseptic and also feed anti-mildew. It has a solid inhibitory impact on perishing microorganisms as well as mold, and also is quickly soluble in water, so it has actually been widely utilized. Its antibacterial development effect is more powerful than antiseptic impact, as well as the reduced the pH value, the more powerful the anti-bacterial result.

Sorbic acid (potassium) can effectively prevent the task of mold and mildew, yeast as well as aerobic bacteria, and also can likewise prevent the development and reproduction of damaging microorganisms such as botulinum, staphylococcus and also salmonella, yet it is ineffective for anaerobic spores as well as acidophilus Beneficial microbes such as Lactobacillus are practically inefficient, as well as their growth-inhibiting effect is more powerful than the bactericidal result, so as to efficiently extend the storage time of food and preserve the initial flavor of food. Its disinfectant result is 5-10 times that of the similar item sodium benzoate. as a cosmetic preservative

Effect of Potassium Sorbate on the Activity of Lactic Acid Bacteria

How to use Potassium Sorbate

1. It can be used in various ways such as direct addition, spraying, dipping, dry powder spraying, and processing on packaging materials.

2. Potassium sorbate has incompatibility with alkali, oxidizing and reducing agents. The antibacterial activity of sorbic acid will be reduced when it encounters non-ionic surfactants and plastics. Heavy metal salts can catalyze oxidation reactions. Sorbic acid can also react with sulfur-containing amino acids, but this reaction can be inhibited by adding vitamin C, propyl gallate or butylated hydroxytoluene.

3. When the solution is stored in a glass container, it is very sensitive to pH. Therefore, preparations using potassium sorbate as a preservative need to be tested for the amount of microorganisms after being stored for a long time.

4. If the sorbic acid solution is stored in polypropylene, polyvinyl chloride or polyethylene containers without adding antioxidants, sorbic acid will degrade quickly.
