Ammonium sulfate is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. It is also used as an agricultural spray adjuvant for water-soluble insecticides, herbicides, and fungicides.
As a food additive, ammonium sulfate is designated by the E number E517. It aids in controlling the pH of flours and baked products. It is mostly used as a dough conditioner, surfactant, or dough strengthener, ammonium sulfate supplies extra nitrogen for the yeast to consume promoting product consistency, volume, crumb, and shelf life. It is approved to use as food additive in EU.
