Chinese Factory Supply Best Potassium Sorbate Organic preservatives

  Product Detail  

• Potassium sorbate, also known as potassium 2,4-hexadienoate, is the potassium salt of sorbic acid with the molecular formula C6H7O2K. It occurs as colorless or white flaky crystals or a crystalline powder. It is odorless or slightly odorous. Long-term exposure to air can lead to moisture absorption, oxidation, and discoloration. It is readily soluble in water (58.2g/100mL at 20°C). Potassium sorbate is a commonly used organic preservative, widely used in food, cosmetics, and feed. It is easily absorbed and metabolized by the human body, leaving no residue and exhibiting no toxicity.

Potassium sorbate is a common food preservative, primarily used to inhibit microbial growth and extend shelf life. It is highly safe and has a wide range of applications. It is widely used in food, daily necessities, and pharmaceuticals. It exerts its antibacterial effects by creating an acidic environment, significantly inhibiting molds, yeasts, and other fungi.

I. Functions of Potassium Sorbate
Antimicrobial Activity 1.
It inhibits the growth of molds, yeasts, and aerobic bacteria by disrupting microbial enzyme systems. It is particularly suitable for acidic environments (pH < 6.5).

Extends shelf life 2.
Reduces the risk of food spoilage, preserves flavor and nutritional value, and is milder than traditional preservatives (such as sodium benzoate).

High Safety 3.
It metabolizes carbon dioxide and water, is harmless to the human body at standard doses, and is recognized as a safe additive by international organizations (such as the WHO).

II. Uses of Potassium Sorbate
Food Industry 1.
It is added to processed foods: juices, jams, canned goods, and baked goods (bread and cakes) to prevent mold. Dairy products: Inhibit yeast contamination in cheese and yogurt.
Condiments: Extend shelf life in soy sauce and dressings.
Daily Chemicals 2.
Prevent microbial growth and improve product stability in cosmetics, shampoos, and skincare products.
Pharmaceuticals 3.
Used as an excipient in some medicines and ointments to inhibit drug deterioration (must comply with medical standards).
