Applications
Food Industry
In the food sector, ammonium sulfate serves as an acidity regulator in flour
and bread. The food-grade variant of ammonium sulfate has received recognition
as safe by both the US FDA and the European Union.
Agriculture Industry
Within the realm of agriculture, ammonium sulfate finds utility as a
fertilizer for crops cultivated in alkaline soil. The addition of ammonium
sulfate to alkaline soil results in the release of ammonium ions, accompanied
by a slight acidification of the soil, thereby reducing its pH. Beyond this,
it serves as a nitrogen source, promoting plant growth.
Horticulture Industry
In horticulture, ammonium sulfate is employed as a spray adjuvant for water-soluble
insecticides, herbicides, and fungicides. Its role is to bind iron and calcium
cations present in the water.
Analytical Uses
Ammonium sulfate plays a crucial role in analytical applications, particularly
in purifying proteins through selective precipitation or salting out.
This method facilitates the separation of complex protein mixtures.
Other Applications
Notably, ammonium sulfate is listed as an ingredient in numerous US vaccines by the Centre for Disease Control.
