Production Technology
Food-grade Disodium Hydrogen Phosphate is produced by neutralizing
phosphoric acid with sodium hydroxide in a controlled environment.
After neutralization, the resulting solution is crystallized,
filtered, and dried to remove impurities, producing a high-purity,
white crystalline powder. The product undergoes rigorous testing
for quality control and is packaged to meet food-grade standards
for safety.
Theory
Disodium Hydrogen Phosphate (Na₂HPO₄) dissociates in water to
release sodium (Na⁺) and hydrogen phosphate (HPO₄²⁻) ions. Sodium
plays a key role in regulating electrolyte balance, while phosphate
is critical for energy metabolism and cellular functions. The
product's buffering properties help maintain pH within desired
ranges, ensuring product stability and consistency. This is
especially useful in food systems where pH control is necessary to
preserve flavor, texture, and nutritional content. Additionally,
its emulsifying properties help in the formation of stable
emulsions, contributing to improved mouthfeel and texture in food
products.
