Product Overview

Sodium acetate exists in anhydrous and trihydrate forms. It is a mild, stable organic salt, commonly known as E262 in food industry. It functions as acidity regulator, buffer and preservative. It can maintain stable pH environment, restrain the growth of microorganisms and extend the shelf life of finished products.

Key Product Characteristics

1. Excellent pH buffering capacity, keeps stable acidity during food processing

2.Mild property, does not affect the original flavor of raw materials

3.Good water solubility, easy to mix evenly in production systems

4.Stable chemical properties under regular processing temperature

5.Dual available forms: anhydrous sodium acetate and trihydrate sodium acetate

Main Functions

Sodium acetate acts as acidity regulator, pH buffer, preservative and flavor stabilizer. It controls pH fluctuation, inhibits bacteria and mould, and protects product quality during storage.

Application

1. Food Industry 

Used in processed meat, sauces, pickles, snacks and ready-to-eat food. It adjusts acidity, preserves freshness and stabilizes flavor.

2. Industrial Field

Used in textile printing, electroplating, wastewater treatment and concrete additive as buffering agent.

3. Other Applications

Also applied in laboratory reagent and chemical synthesis.

Packaging & Storage

Packaging Specification: 25kg full fibre drum

Storage Condition: Store in cool, dry and ventilated warehouse. Keep sealed and avoid moisture.

Shelf Life: 24 months under proper storage

Sodium Acetate is chemically designated CH3COONa, a hygroscopic powder very soluble in water. Sodium acetate anhydrous is white crystalline coarse powder or block. It’s odorless, tastes a bit of vinegary, used as food preservatives or acidity regulator.
