What is the Full Form of DAP?

The full form of DAP is Diamine phosphate. Diamine phosphate (DAP) is a water-soluble ammonium phosphate salt. Its IUPAC name is diammonium hydrogen phosphate, and its chemical formula is H₉N₂O₄P. This compound can be synthesized by combining ammonia with phosphoric acid. DAP has a rich history of biopreservation of plant products like seeds and fruits. 

Furthermore, it finds applications in food preservation and contributes to the creation of medicinal products like “dextrose dihydrogen phosphate” (DHDHP), used in parenteral anti-influenza medication.  


The structure of DAP consists of two molecules of diammonium hydrogen phosphate (NH₄HPO₄) along with H₂N₂O₄P and H₃N₂O₄P. Diammonium hydrogen phosphate is a colourless solid with a molecular formula H₂N₂O₄P, a molecular weight of 203.32 g/mol, a density of 1.131 g/cm³, a melting point of (not mentioned), and a refractive index of 1.585 – 1.587.  


Let’s have a look at some of the uses of DAP:

  • DAP has various uses in the food industry, including its role as an acidity enhancer for bread, rolls, and winemaking. 
  • Additionally, it acts as an antioxidant, scavenging free radicals and preserving foods like apples and wine. 
  • Research conducted at the University of Puerto Rico, Mayagüez, has shown that DAP can inhibit the growth of the “Staphylococcus aureus” bacterium responsible for food spoilage when applied to the surface of fruits and vegetables. 
  • Moreover, diammonium hydrogen phosphate serves as a buffering agent, regulating acidity levels in food and enhancing texture and taste by preventing the staling process that leads to flavour, colour, and nutritional loss in baked goods exposed to air.
  • It is utilized to prevent food spoilage in items like whole egg powder and skimmed dried milk. 
  • Additionally, in cheese processing, it serves as a buffering agent to regulate acidity, enhance flavor, and improve texture. 
  • Furthermore, it effectively inhibits the growth of yeast, mould, and bacteria, helping to preserve and extend the shelf life of foods like cheese, gums, and frozen citrus fruit.
