2. Product Introduction

Ammonium Sulfate is an inorganic salt with the chemical formula (NH₄)₂SO₄. It is produced through the neutralization of ammonia with sulfuric acid, followed by crystallization, separation, drying and purification. The product is available in food grade and industrial grade, both of which are widely used in food processing, agriculture, chemical manufacturing, pharmaceutical production and other industrial fields.

Food Grade Ammonium Sulfate is used as an acidity regulator, firming agent, leavening agent and processing aid in food production. It helps control acidity, improve texture and support certain fermentation and preparation processes. Industrial Grade Ammonium Sulfate is mainly applied as a nitrogen source in fertilizers, a raw material in chemical synthesis, a crystallization agent in pharmaceutical production, and a processing agent in various industrial processes.


Main Functions:

1. Food Grade Functions

1.1.Acidity Regulation Ammonium Sulfate can adjust and maintain the acidity of food systems. It is used in certain processed foods and beverages to help stabilize pH and support consistent processing conditions.

1.2.Firming Agent It helps improve the firmness and texture of some food products. By interacting with food components, it can support a more stable structure and better mouthfeel.

1.3.Leavening Aid In some baked goods and fermented products, Ammonium Sulfate can act as a leavening aid or processing aid. It supports gas formation and contributes to volume and texture development.

1.4.Processing Aid Ammonium Sulfate is used as a processing aid in food manufacturing. It may assist in protein precipitation, crystallization control and other technical operations during production.

1.5.Nutrient Source in Fermentation It can serve as a nitrogen source in fermentation processes. For certain microbial preparations and food fermentation systems, it supports microbial growth and production efficiency.

2.Industrial Grade Functions

2.1.Fertilizer: Provides nitrogen and sulfur for crop nutrition.

2.2.Chemical Raw Material: Used in the production of ammonium salts, sulfates and other chemicals.

2.3.Pharmaceutical Intermediate: Applied in drug synthesis and crystallization processes.

2.4.Textile Additive: Used in dyeing and textile processing operations.

2.5.Water Treatment: Applied in certain water treatment and chemical treatment processes.
