Product Overview

Potassium Sorbate E202 is the potassium salt form of Sorbic Acid E200, recognized as one of the safest and most widely used E-series food preservatives globally. Compared with Sorbic Acid E200, Potassium Sorbate E202 features excellent water solubility, easy dispersion and convenient application.

Potassium Sorbate E202 exerts strong inhibitory effects on mold, yeast and aerobic bacteria, effectively preventing food and feed spoilage. It retains the original flavor, color and nutrition of products without peculiar smell, suitable for most acidic and neutral food systems.

 

Key Product Characteristics

1.food grade safe preservative with low toxicity

2.Excellent water solubility, easy to dissolve and use

3.High efficiency against mold, yeast and spoilage bacteria

4.No strange odor, does not affect product taste and color

5.Wider application range than Sorbic Acid E200

6.Stable thermal performance during food processing

7.Available in food grade and feed grade Potassium Sorbate E202

 

Main Functions in foods

Mold Inhibition: Potassium Sorbate  strongly suppresses mold growth in high-moisture food

Yeast Inhibition: prevents yeast over-fermentation and product deterioration

Bacteria Suppression:  inhibits aerobic spoilage bacteria to reduce contamination risk

Fresh-Keeping & Shelf Extension: Potassium Sorbate effectively extends storage and shelf life of various foods

 

Application in foods

Carbonated drinks, fruit juices, tea beverages, wine, yogurt and dairy products, bakery goods, jams, preserves, pickles, sauces, canned fruits and vegetables, processed meat products, snacks and confectionery, all suitable for Potassium Sorbate E202 preservation.

 

Potassium Sorbate vs Sorbic Acid: Key Differences

Product

Similarity

Main Difference

Typical Focus

Potassium Sorbate E202

Same antibacterial and preservative principle, safe E-series food additive

Potassium salt form, high water solubility, easy to use, wider pH adaptation

First choice for beverages, dairy, sauces, high-moisture liquid and semi-liquid foods

Sorbic Acid E200

Same antibacterial and preservative principle, safe E-series food additive

Acid form, poor water solubility, suitable for strong acidic systems

Solid bakery, low-moisture food, feed mildew prevention
