Product Overview

Sodium Propionate is a widely used acid-type food preservative belonging to the propionate salt series. Compared with Calcium Propionate, Sodium Propionate features much better water solubility, making it the preferred preservative for liquid foods, sauces, drinks and high-moisture food systems.

It effectively inhibits mold, bacteria and microorganisms, prevents food mildew and deterioration, and greatly extends product shelf life. It is safe, stable and compliant with international food additive standards. Feed grade and pharmaceutical grade are optional for secondary application scenarios.

Character

Sodium Propionate is a white, odorless or slightly faint characteristic crystalline powder. It presents excellent water solubility and stable chemical properties under normal storage conditions. The ingredient shows good compatibility with most common food additives and does not alter the original flavor and color of finished food products.

Core Product Functions

Sodium Propionate acts as an effective food-grade preservative. It mainly inhibits the growth and reproduction of molds, yeasts and harmful bacteria in food. It effectively prevents food spoilage and microbial deterioration, thereby significantly extending the shelf life of various food products.

Application Scope

1. Food Industry

Bakery Food: Bread, cakes, pastries, steamed buns, dumpling wrappers and noodle products.

Condiments & Sauces: Soy sauce, vinegar, jam, pickled vegetables and various brine seasonings.

Beverage & Liquid Food: Fruit drinks, functional beverages and liquid protein products.

Canned & Preserved Food: Canned fruits and preserved wet food for anti-mildew preservation.

2. Feed Industry

Anti-mildew and fresh-keeping additive for livestock and poultry feed raw materials.

3. Pharmaceutical Industry

Auxiliary preservative raw material for pharmaceutical preparations.
