Disodium Phosphate (DSP) · Buffer, Emulsifying Salt & pH Regulator for Food Processing

Disodium phosphate (DSP), also known as sodium phosphate dibasic or disodium hydrogen phosphate (Na2HPO4), is a widely used food-grade phosphate buffer and pH regulator. It helps stabilize acidity in beverages and dairy systems, supports processing consistency, and is used as part of emulsifying salt systems in processed cheese and cheese sauces. In certain meat and poultry applications, phosphate systems can contribute to water binding and texture (where permitted and correctly labeled). Atlas Global Trading Co. supplies disodium phosphate in common hydration forms (e.g., anhydrous, dihydrate or other specified grades), supported by COA, technical documentation and reliable global logistics.

Function: Phosphate buffer & pH regulator; part of emulsifying salt systems in processed cheese
Typical forms: anhydrous or hydrated (commonly dihydrate) powders; food grade for consistent buffering performance
Key feature: Reliable pH control and mineral management to support stability, texture and processing robustness

DSP is often used together with other phosphates (pyrophosphates, tripolyphosphates) and citrates for targeted pH and functional performance. Explore the full Phosphates portfolio or browse our Product Index (A–Z) for complementary buffers and functional ingredients.

Product overview

DSP: sodium phosphate buffer for consistent pH and process stability

Disodium phosphate is a versatile phosphate salt used to manage pH and ionic balance. In food systems, buffering helps stabilize flavor and processing conditions, improves robustness during heat treatment, and supports emulsification in selected dairy and processed cheese applications. DSP can be supplied in different hydration states, and the best choice depends on formulation, solubility requirements and handling preferences.

Key characteristics

  • Chemical identity: disodium phosphate (Na2HPO4), also known as sodium phosphate dibasic.
  • Forms: anhydrous and hydrated grades (commonly dihydrate) available depending on specification.
  • Appearance: white, free-flowing crystals or powder.
  • Solubility: readily soluble in water, suitable for buffer solutions and process liquids.
  • Functional roles:
    • Buffering / pH regulation: stabilizes acidity and supports consistent processing.
    • Sequestration (limited): helps manage mineral balance in some systems.
    • Emulsifying salt contribution: used in phosphate systems for processed cheese and cheese sauces.
    • Processing support: contributes to robustness in certain heat-treated and dairy systems (application dependent).
  • Regulatory & labeling:
    • Declared as “disodium phosphate”, “sodium phosphate dibasic” or equivalent regional naming.
    • Phosphate additive group permissions and maximum levels vary by market and category (notably for meat/poultry/seafood).

Atlas supports customers in selecting DSP hydration state and grade to match solubility needs, pH targets and regulatory frameworks.

Indicative specification points

Specifications vary by producer and hydration state. Typical parameters include:

  • Assay: defined Na2HPO4 content on dry basis (grade dependent).
  • pH (solution): specified pH range at defined concentration (buffer characteristic).
  • Loss on drying / water of crystallization: controlled to match hydration state and stability.
  • Insoluble matter: limited to ensure clarity in solutions.
  • Particle size: defined range for dissolution and blending performance.
  • Heavy metals and impurities: restricted to meet food-grade requirements.
  • Microbiological criteria: managed per applicable food ingredient standards.

Each batch is supplied with a Certificate of Analysis (COA) and a technical data sheet. Additional documents (GMO status, allergen statements, dietary suitability, origin, Halal/Kosher certificates where applicable) can be provided depending on grade and producer.

Applications

Disodium phosphate applications in dairy, beverages, processed cheese and food processing

DSP is selected for buffering, pH control and functional performance in multiple categories. Below are common use cases and practical goals.

Dairy & dairy-based processing

  • Buffering support in dairy systems where pH stability is critical during processing.
  • Improves process robustness in heat-treated dairy applications (formulation dependent).
  • Used in selected dairy powders and dairy-based blends as a functional buffer (project dependent).

Processed cheese & cheese sauces

  • Used as part of emulsifying salt systems to support smooth texture and stable emulsions.
  • Helps manage pH and calcium balance, supporting melt and sliceability (system dependent).
  • Applied in cheese spreads, cheese sauces and processed cheese formulations as permitted.

Beverages (selected)

  • Used in buffer systems where pH stabilization is needed for flavor and ingredient compatibility.
  • Supports stability in certain beverage concentrates and syrups (application dependent).

Meat & poultry processing (where permitted)

  • Phosphate systems can support water binding and texture in brines and marinades (regulation and labeling dependent).
  • DSP may be used as part of multi-phosphate solutions designed for yield and quality targets.

Bakery & dry mixes (selected)

  • Used in certain dry mixes and process concepts where buffering is required (application dependent).
  • Can be incorporated into custom premix systems with controlled particle size for uniformity.

Formulation guidance

  • Hydration state affects weight and handling; select the correct form for consistent dosing.
  • For buffer design, evaluate pH target, ionic strength and compatibility with other ingredients (citrates, acids, salts).
  • For processed cheese, optimize phosphate system selection (DSP with other phosphates) to achieve desired melt/texture.
  • For meat/poultry, confirm permitted phosphate types, maximum levels and labeling requirements in destination markets.
