4. Applications in Food Processing

Food Grade Ammonium Sulfate is indispensable in several key areas:

• Baking Industry (Primary Use): Used as a dough conditioner and yeast nutrient in bread, rolls, and other yeast-leavened products. It provides a rapid source of nitrogen for yeast, ensuring vigorous and consistent fermentation, which improves dough elasticity, gas retention, and final loaf volume.

• Flour Treatment Agent: Often added directly to flour as a standardizing agent and improver.

• Brewing & Fermentation: Acts as a yeast nutrient in the production of beer, wine, and other fermented beverages to support healthy and complete fermentation.

• Other Food Uses: Permitted for use as an acidity regulator and firming agent in certain food systems.

5. Features & Benefits

• Essential Yeast Nutrition: Provides a highly bioavailable and immediate source of nitrogen, which is critical for consistent yeast activity and predictable fermentation times.

• Improves Baking Performance: Enhances dough development, stability, and oven spring, leading to baked goods with better volume, finer crumb structure, and improved texture.

• Cost-Effective & Efficient: A highly economical and potent solution for controlling fermentation compared to other nitrogen sources.

• High Purity & Food Safety: Manufactured and handled under strict food-grade controls, ensuring a product free from harmful contaminants.

• Standardizes Production: Helps bakers achieve consistent results batch after batch, regardless of natural variations in flour.

• Reliable Supply: We ensure a steady and dependable supply of this essential processing aid to keep your production lines running smoothly.

6. Packaging & Storage

• Standard Packaging: 25 kg multi-ply paper bags with an inner polyethylene liner. Also available in 50 kg bags or larger bulk quantities (e.g., 1000 kg Big Bags) for high-volume users.
