Product Description

Introduction to Potassium Sorbate

1. Definition

Potassium sorbate, chemically known as potassium 2,4-hexadienoate, is a white to slightly yellowish crystalline powder or granule. It is the potassium salt of sorbic acid and is widely recognized as a highly effective and safe preservative. Derived from sorbic acid through a neutralization reaction with KOH, it inhibits the growth of molds, yeasts, and some bacteria, extending the shelf-life of various products without altering their taste, smell, or nutritional value significantly.

2. Physical and Chemical Properties

• Appearance: Typically appears as a white, odorless powder or granule. It is highly soluble in water, with a solubility of about 58.2 g per 100 mL at 20°C.

• Melting Point: The melting point of potassium sorbate is around 270°C, where it decomposes rather than melts like typical substances.

• pH Influence: In an aqueous solution, it hydrolyzes to form sorbic acid, and its effectiveness as a preservative depends on the pH of the medium. It performs best in acidic environments (pH 4 - 6).

3. Production Methods

• Neutralization: The most common method involves reacting sorbic acid with KOH in an aqueous solution. The reaction is straightforward, and the resulting solution is then evaporated to crystallize potassium sorbate.

• Esterification and Subsequent Reaction: Another approach starts with the esterification of crotonaldehyde and acetic anhydride to form sorbic acid esters, which are then hydrolyzed and reacted with KOH to produce potassium sorbate.

4. Storage Methods

• Sealed Containers: Potassium sorbate should be stored in tightly sealed containers to prevent moisture absorption. Exposure to air can cause it to gradually absorb water, affecting its quality and performance.

• Cool and Dry Place: It should be kept in a cool, dry environment, away from direct sunlight and heat sources. Temperatures between 0 - 30°C are ideal for maintaining its stability.

• Separation from Reactive Substances: Avoid storing it with strong oxidizing agents, acids, or bases, as these may react with potassium sorbate and degrade its properties.

5. Market Information

• Global Demand: The global market for potassium sorbate has been growing steadily due to its wide applications in food, beverage, and personal care industries. The increasing consumer demand for clean-label products has also contributed to its rising popularity.

• Key Producers: Major producers are located in regions like Asia, Europe, and North America. Competition among producers is intense, driving continuous improvements in production efficiency and cost reduction.

6. Downstream Industry Chain

• Food Industry: The primary downstream user, including baked goods, dairy products, and processed meats, where it prevents spoilage.

• Beverage Industry: Used in fruit juices, soft drinks, and wine to inhibit microbial growth and maintain product quality.

• Personal Care Industry: Incorporated into cosmetics, lotions, and shampoos to prevent the growth of microorganisms and extend product shelf-life.

Application

Food Preservation: In food products, potassium sorbate controls the growth of spoilage organisms, ensuring food safety and freshness. For example, it helps keep bread from molding and extends the shelf-life of jams and jellies.
Beverage Preservation: In beverages, it prevents the fermentation and spoilage caused by yeasts and bacteria, maintaining flavor and clarity.
Personal Care Products: In the personal care sector, it acts as a preservative, protecting products from contamination and ensuring their usability over time.
