Product Overview

Sorbic Acid is an unsaturated fatty acid preservative. It works mainly in the acidic pH range and is widely used to prevent mold, yeast and bacterial growth in food and feed.

Because it is an acid-form preservative, it is particularly suitable for acidic food systems. It helps maintain product quality and extend shelf life.

 

Key Product Characteristics

1.Effective against mold, yeast and bacteria

2.Suitable for acidic food systems

3.Good thermal stability during processing

4.Available in food grade and feed grade

5. Often used as an alternative or companion to potassium sorbate

 

Main Functions

1. Food Grade Functions 

Mold Inhibitor: Prevents mold growth in bakery, beverages, condiments and canned foods.

Yeast Inhibitor: Helps control yeast fermentation and spoilage.

Bacteria Control: Reduces the risk of bacterial contamination.

Preservative: Extends shelf life and maintains product freshness.

 

2. Feed Grade Functions 

Used as a preservative and mold inhibitor in animal feed.

 

Application Scope

 

Food Industry: Bakery products, beverages, fruit juices, condiments, pickles, canned foods, jams and dairy products.

Feed Industry: Animal feed and feed raw materials where mold control is required.

 

Sorbic Acid vs Potassium Sorbate: Key Differences

 

Product Similarity Main Difference Typical Focus
Sorbic Acid Antimicrobial and preservative activity Acid form; lower water solubility; more suitable for acidic systems Mold control, yeast control, acidic food preservation
Potassium Sorbate Antimicrobial and preservative activity Potassium salt form; higher water solubility Beverages, sauces, dairy, high-moisture foods
