Potassium sorbate is a normal food additive, which has antiseptic effect. This has little impact on human body, but don't eat too much, which may lead to allergies and abnormal gastrointestinal digestion, especially if your child is allergic. Usually, it is best to choose snacks that are natural, or foods with less additives and preservatives are better.

Potassium sorbate-colorless to white scaly crystals or crystalline powder, odorless or slightly smelly. Unstable in air. Can be oxidized and colored. Molecular weight 150.22. It is hygroscopic. Soluble in water and ethanol. Mainly used as food preservative, which belongs to acidic preservative and is used with organic acid to improve the antiseptic reaction effect. Is prepared from potassium carbonate or potassium hydroxide and sorbic acid.

Sorbic acid (potassium) can effectively inhibit the activities of mold, yeast and aerobic bacteria, thus effectively prolonging the storage time of food and maintaining the original flavor of food. When we buy packaged (or canned) food, we often see the words "sorbic acid" or "potassium sorbate" in the item of ingredients. In fact, they are commonly used food additives.

Sorbic acid (potassium) is an acidic preservative, which still has a good antiseptic effect in foods close to neutral (PH6.0-6.5) (not suitable for dairy products). Sorbic acid (potassium) is an efficient and safe preservative recommended by FAO and WHO, which is widely used in food, beverage, tobacco, pesticides, cosmetics and other industries. As an unsaturated acid, it can also be used in resin, perfume and rubber industries.
