Product Description
Potassium sorbate, chemically represented by the formula C6H7KO2, is the potassium salt of sorbic acid, a widely utilized preservative in various industries. As a white to pale yellow crystalline powder or granules with little to no odor, it exhibits excellent solubility in water (approximately 58.2g/100mL at 20°C) and slight solubility in ethanol, with its aqueous solution showing weak alkalinity. Its preservative efficacy predominantly relies on sorbic acid, which penetrates microbial cell membranes, inhibits key enzymes such as dehydrogenases and oxidases, and disrupts metabolic processes, thereby preventing the growth and reproduction of molds, yeasts, and bacteria.
In the food industry, potassium sorbate serves as a primary defense against spoilage. It is extensively used in a variety of products: in meat products like sausages and hams, its maximum allowable usage ranges from 0.075 to 0.15g/kg (in accordance with GB 2760 standards); in beverages such as fruit juices and carbonated drinks, the dosage is typically capped at 0.2g/kg; and in bakery items like bread and cakes, it is added at a concentration of 0.1 - 0.2g/kg. Beyond food, it plays crucial roles in the brewing industry by controlling bacterial contamination during wine fermentation, in the tobacco sector by preventing mold growth to maintain product quality, and in the manufacturing of plastics, rubbers, water-based coatings, and adhesives, where it protects materials from microbial degradation and enhances durability.

Application
meats, the maximum usage is typically controlled at 0.075-0.15g/kg (in accordance with GB 2760 standards). For beverages including carbonated drinks, fruit juices, and protein drinks, the dosage generally does not exceed 0.2g/kg. In bakery products like bread, cakes, and mooncakes, about 0.1-0.2g/kg of potassium sorbate is added to inhibit mold reproduction. For pickled vegetables such as pickles, salted vegetables, and pickled cucumbers, the dosage is ≤0.5g/kg. Its mechanism of action mainly involves inhibiting the activity of microbial enzymes in the form of sorbic acid (the active component), thereby interfering with the metabolic processes of microorganisms to achieve the effect of antiseptic and preservation.
Brewing Industry
Controls contamination by miscellaneous bacteria during the fermentation process, especially commonly used in the brewing of fruit wines and wines.
Tobacco Industry
Added to tobacco products to inhibit mildew and maintain quality.
Plastics and Rubbers
As an additive, it prevents polymer materials from microbial erosion during storage, enhancing product durability.
Coatings and Adhesives
Used in water-based coatings, glues and other products to prevent deterioration or performance degradation caused by microbial reproduction.
Packaging & Shipping
Temperature: It is suitable to be stored in a cool environment. The ideal storage temperature is below 20°C. Excessively high temperatures can easily cause potassium sorbate to decompose and become inactivated, reducing its application effect. Some materials also mention that the storage temperature should not exceed 40°C, but low temperatures are more conducive to long - term stable storage.
Humidity: The relative humidity should be kept below 50%. High humidity will make it absorb moisture, resulting in caking problems and affecting use. Containers with good airtightness (such as glass bottles, plastic bottles, etc.) should be used to block the invasion of moisture. The storage environment should also be dry and away from water sources.
