What is Ammonium Sulfate ?
Food-grade ammonium sulfate, scientifically known as ammonium sulfate, has a CAS number of 7783-20-2, a molecular formula of (NH4) 2SO4, and a molecular weight of 132.14. Food-grade ammonium sulfate is a purified ammonium sulfate ((NH₄)₂SO₄) salt that meets food safety standards. It is mainly used as a processing aid in the food industry, especially as a nitrogen source in the field of yeast fermentation. It also serves as a dough conditioner and flour treatment agent. The international code for food additives is E517. Thuộc tính: Colorless and transparent rhombic crystals, relative density 1.769, readily soluble in water, the aqueous solution is acidic, insoluble in alcohol, acetone and ammonia, releases ammonia gas when reacting with alkalis, hygroscopic.
What is ammonium sulfate used for?
Ammonium sulfate is not only used as a food additive in the food industry but also finds applications in other fields. For instance, in agriculture, it is mainly used as a nitrogen-sulfur compound fertilizer. Industrial-grade ammonium sulfate, which is of high purity, is widely applied in chemical materials, textiles and leather, water treatment, medical industry and batteries. It is a basic and versatile chemical.
Ammonium sulfate in food application
The ammonium sulfate supplied by KosNature has been widely used in food as a dough conditioner and flour treatment agent, making the dough more elastic and resilient and improving its processing performance. It is also used as a nitrogen source nutrient for yeast. After adding ammonium sulfate, it can significantly promote the vitality and reproduction rate of yeast, thereby accelerating dough fermentation and making the fermentation process more stable and thorough. It is also used in beer brewing as a yeast nutrient. It is a rare functional food ingredient.

FRQ
In the food industry, ammonium sulfate (chemical formula: (NH₄)₂SO₄) is a food additive approved by regulations (with the international code E517). It must meet the “food grade” purity standard, which means that the content of harmful impurities such as heavy metals (such as arsenic and lead) is strictly controlled below the safety limit. Its core functions include: yeast nutrient (nitrogen source), dough conditioner, and flour treatment agent.
Food-grade ammonium sulfate (E517) is safe when used within the regulatory limits. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have both evaluated it and approved its use in specific food categories as needed or within specified maximum limits. Tuy nhiên, it is important to note that industrial-grade ammonium sulfate must never be consumed as it is toxic. Industrial-grade products contain uncertain amounts of harmful impurities such as heavy metals, sulfides, and fluorides, which are the main sources of health risks. Accidental ingestion may cause gastrointestinal irritation, nausea, vomiting, and other symptoms of poisoning.
Ammonium sulfate is a versatile chemical with applications spanning both agricultural and industrial sectors. Agricultural uses (the main application, accounting for over 80% of global consumption):
Nitrogen-sulfur compound fertilizer: It provides approximately 21% nitrogen (ammonium nitrogen) and about 24% sulfur. Both of these are essential key nutrients for plant growth. It is particularly suitable for sulfur-loving crops and alkaline soils.
Industrial uses:
Chemical and metallurgical industries: The key application is as an extraction agent for extracting and separating rare earth elements from rare earth ores.
Công nghiệp thực phẩm: As a yeast nutrient and processing aid (E517) as mentioned above.
Textile and leather: As a leveling agent in wool dyeing and for tanning in the leather industry.
Xử lý nước: As a dechlorinating agent to remove residual chlorine from drinking water.
Flame retardants: Used in the manufacture of intumescent fireproof coatings.
Biotechnology: In protein purification, it is used as a high-concentration salt for ammonium sulfate precipitation to separate and purify proteins.
