Uses: Ammonium Sulfate is a dough conditioner, firming agent, and pro- cessing aid which is readily soluble in water with a solubility of approximately 70 g in 100 g of water at 0°c. the ph of a 0.1 molar solution in water is approximately 5.5. it is used in caramel produc- tion and as a source of nitrogen for yeast fermentation. in bakery products, up to 0.25 part per 100 parts by weight of flour is used.
Agricultural Uses: Ammonium sulphate, (NH4)2SO4, a water-soluble crystalline salt is a nitrogenous fertilizer containing about 2 1 % nitrogen and 24 % sulphur. It occurs naturally as the mineral mascagnite and offers many advantages as a fertilizer, such as low hygroscopicity, good physical properties, excellent chemical stability, good agronomic effectiveness and long shelf life.
