Product Overview

Sodium Acetate (E262) exists in two forms: anhydrous and trihydrate. It is the sodium salt of acetic acid with outstanding pH buffering performance. As a pH buffer and acidity regulator for food processing, it stabilizes pH value and suppresses microbial growth to prolong shelf life. It is widely adopted in sauces, pickles, processed meat and bakery products. It also has applications in water treatment, textile and other industrial fields.

 

Core Characteristics

1.Excellent pH buffering capacity, stabilizes acid-base balance in food systems

2.Mild preservative effect, inhibits mold and bacterial growth

3.Freely soluble in water, easy to dissolve and distribute

4.Available in anhydrous and trihydrate forms for different processing needs

 

Main Functions

1.pH Buffer Sodium Acetate delivers strong pH buffering capacity, resisting sudden pH shifts and maintaining stable acidity throughout food processing and storage. It keeps consistent flavor and quality for acidified food systems.

2.Acidity Regulator It adjusts and fine-tunes the acidity level of food formulations, balancing sharp sour taste and optimizing the overall flavor profile.

3.Preservative In suitable pH conditions, sodium acetate inhibits molds, yeasts and spoilage bacteria, extending product shelf life, often used synergistically with other preservatives.

4.Industrial Application Serves as raw material in water treatment, textile dyeing and other industrial processes.

 

Applications

1.Sauces, Dressings & Condiments  Used in sauces, ketchup, mayonnaise and salad dressings to stabilize pH, adjust acidity and extend shelf life.

2.Pickles & Fermented Vegetables Applied in pickled vegetables to maintain consistent acidity, improve flavor stability and inhibit spoilage microorganisms.

3.Processed Meat Products Used in sausages, ham and cured meats as pH buffer, preservative and flavor modifier.

4.Bakery & Snack Foods Applied in bread, cakes and snack foods to stabilize dough pH, retard staling and extend freshness.

5.Other Food Applications Also used in ready-to-eat meals, seasonings and various processed…
