DAP (Diammonium Phosphate)

Diammonium phosphate (DAP) is a food grade inorganic salt made of ammonium and phosphate ions. It dissolves easily, appears under INS or E number 342, and is valued for its roles in fermentation, dough development, and pH stability. 

Its primary function is yeast nutrition, supplying accessible nitrogen and phosphorus that help yeast activate, grow, and complete fermentation reliably in bread, wine, fruit wine, cider, mead, and beer. 

DAP also provides mild buffering support, helping maintain steady pH in doughs and fermenting liquids. It disperses smoothly in dry blends, dough conditioners, and fermentation bases, integrating cleanly into systems that depend on consistent, predictable performance. 

DAP finds a comfortable home in many categories because it solves practical, process level challenges without drawing attention. 

Bakery 

• Supports yeast activity in doughs needing predictable fermentation.  

• Helps maintain consistent rise and structure in bread and unstandardized bakery items.  

• Works well in dry blends where controlled pH and functional phosphates improve handling.  

Sports Nutrition 

While not a primary ingredient in consumer ready sports mixes, DAP appears upstream in fermentation driven ingredient production. 

• Contributes to fermentation processes used to create nutrient enriched bases.  

• Supports stable pH and fermentation environment for select functional ingredients.  

Meat and Prepared Foods 

• Supports pH balance and texture in systems that benefit from mild buffering.  

• Offers phosphate functionality in sauces, gravies, and process tolerant blends.  

Fruits and Vegetables 

• Helps maintain predictable fermentation environments in fruit wines and related beverages.  

• Plays a supporting role in stabilizing pH in select fruit-based formulations.  

Plant Based 

• Contributes nitrogen and phosphorus for fermentation-based flavour development systems.  

• Helps maintain consistency in enzyme or culture driven plant protein preparations where pH stability matters.  

Functionality 

• Yeast nutrient: Provides ammonium and phosphate ions for fermentation driven products.  

• pH control: Supports slightly alkaline buffering to help stabilize recipes.  

• Dough conditioning and leavening: Aids structure and handling in select bakery systems.  

Grade and Purity 

• Food grade DAP is produced under strict specifications, with typical assays above 99 percent, low moisture, and controlled impurities. Ideal where consistency and clean performance matter.  

Physical Form 

Available as fine crystals or granules. 

• Fine crystals disperse quickly in liquid additions. 

• Granular versions blend smoothly into dry mixes.  

Solubility 

• Fully water soluble, allowing quick integration into dough systems, musts, worts, and processing solutions. Hydration is predictable and uniform.  

Regulatory Fit 

• Canada: Permitted as a yeast food in bread, unstandardized bakery products, wine, fruit wine, cider, and honey wine at category specific levels.  

• United States: Recognized by FDA for uses including leavening, fermenting aid, nutrient supplement, and pH control.  

Packaging 

• Offered in common food industry formats such as bags and larger bulk units suitable for blending and commercial batching.  

Quantity 

• We can help determine the right ordering format and minimums to match your production scale. 

Certifications 

• Blendtek is SQF certified and Kosher certified. 

Diammonium phosphate is a steady, functional ingredient that brings nutrient support, pH balance, and formulation dependability to a wide range of applications. Whether you're building a consistent bakery blend, managing fermentation in beverages, or supporting texture and stability in prepared foods, DAP keeps processes predictable and product quality steady.
