When we talk about food ammonia we talk about ammonium bicarbonate (reported on the label with the code 503) for the preparation of yeasts.
In fact, food ammonia is a leavening agent and is found in food as a leavening agent or as a regulator of acidity
The ammonia plant of Azotal produces ammonia in aqueous solution, with a variable title between 20 and 31.75%, starting from anhydrous ammonia and desalted water. The product is mainly used in the industrial, food and pharmaceutical sectors and in the elimination of NOx emissions from waste-to-energy plants.
Characteristics of food ammonia
At room temperature, pure ammonia appears as a colorless gas with a characteristic extremely pungent odor and which at ambient pressure liquefies at a temperature of -77.7 ºC and boils at -33.4 ºC, transforming into a mobile liquid and also it is colorless.
In the early 2000s, world ammonia production stood at around 135 million tonnes a year
