Ammonium Sulfate (Food Grade) – Safe Food Additive for Baking, Brewing & Food Fermentation

Published for: Food Manufacturers, Bakery & Beverage Factories, Food Additive Distributors

Food Grade Ammonium Sulfate (E517) is a safe and compliant food additive processed through special purification and food-grade production procedures. It complies with international FCC and domestic GB food safety standards, with strict control of heavy metals, microbial residues, and harmful impurities. As a multi-functional food ingredient, it is widely used in baking, brewing, and food fermentation industries, serving as a yeast nutrient, dough conditioner, and acidity regulator to optimize food processing effects and improve product taste and quality.

2. Core Advantages
Food-grade ammonium sulfate is characterized by high safety, pure texture, and stable performance. It has no toxic and side effects on the human body after standard use, and will not produce harmful residues in food processing. It can effectively provide nitrogen and sulfur nutrients for yeast and microorganisms, accelerate fermentation efficiency, and make fermentation more sufficient and stable. In baking processing, it optimizes dough structure, improves dough elasticity and stability, avoids collapse and deformation of finished products, and enhances the taste and appearance of bread, pastries, and other baked foods.

3. Main Applications
Bakery Industry: Acts as a dough conditioner to improve dough texture, increase product softness, and stabilize the molding of bread, cakes, and biscuits.
Brewing & Fermentation: Used as a high-efficiency yeast nutrient in beer, wine, and fermented beverage production to promote yeast reproduction and improve fermentation speed and yield.
Fermented Food Processing: Applied in the production of fermented condiments and dairy products to adjust microbial growth environment and optimize product flavor.
Food Acidity Regulation: Moderately adjusts the pH value of food systems, maintains flavor stability, and extends the shelf life of processed food.

4. Storage & Notes

Store in a dry, clean, odor-free food-grade warehouse, away from toxic and harmful substances. Avoid moisture and high temperature environments to prevent caking. Seal tightly after opening the package, and use it up as soon as possible. Strictly follow food additive usage dosage standards, prohibit over-dose use, and keep away from children.
