SODIUM PHOSPHATES
Sodium Hexametaphosphate SHMP
A condensed phosphate commonly assessed for sequestration, dispersion and mineral-management tasks.
INGREDIENT OVERVIEW
SHMP: product profile
Commercial SHMP is described in JECFA as sodium polyphosphate, glassy. Specify the commercial composition rather than assuming a pure, fixed ring molecule from the name.
Also known as: SHMP · Sodium polyphosphate, glassy · Graham's salt
SHMP is relevant when mineral interactions, dispersion or a phosphate system are part of the formulation problem. In a beverage, clarity and sediment may matter most; in a protein food, processing and texture introduce a different set of observations.

Where it may fit.
These are technical starting points, not finished-product performance or use authorizations.
Seafood processing: evaluate quality under the actual brine and storage conditions.
Other formulated foods: screen sequestration and dispersion where permitted.
GRADE & PROCESS
Mineral management with a commercial polyphosphate
Choosing the material
Commercial SHMP is a glassy polyphosphate material. Its name does not define one pure ring compound or one chain-length distribution. Total phosphate, inactive phosphate and solution behavior describe different aspects of a grade.
Planning a useful comparison
Compare the actual process water, mineral load, pH and heating sequence. Record solution preparation, initial clarity and changes after the intended hold or storage period rather than judging only the freshly mixed sample.

These selected composition and physical fields are a reference for comparison, not a complete food-grade acceptance specification or an IngredientCore supply guarantee. Ask us for the specification, test methods and impurity requirements for the proposed grade and source.
On narrow screens, scroll within the table if needed.
| Parameter / stated test conditions | Reference specification | Unit |
|---|---|---|
| Total phosphate as P₂O₅ | ≥ 68.0 | % |
| Inactive phosphate as P₂O₅ | ≤ 7.5 | % |
| Water-insoluble matter | ≤ 0.06 | % |
| pH — 1% solution | 5.8–6.5 | Dimensionless |
The pH concentration is stated in the source. Temperature, concentration basis and analytical methods are not specified.
Request specificationGRADE & SPECIFICATION
Key parameters to confirm.
Review composition and solution behavior alongside purity. A general SHMP label does not settle the source’s phosphate distribution, dissolution behavior or suitability for the proposed food.
These are procurement questions, not a supplied specification. Units below indicate reporting context, not acceptance limits. Compare the current grade, source, document revision and test method before agreeing values.
If columns extend beyond the frame, scroll the table horizontally.
| Parameter | What to request | Units or test context | Why it matters |
|---|---|---|---|
| Identity and composition | Declared commercial material and composition basis | Source definition and analytical method | Connect the name SHMP to the material actually offered. |
| Phosphate content | Reporting basis and test method | % as the specified analyte | Avoid comparing unlike expressions of phosphate content. |
| pH and solution preparation | Concentration, temperature and preparation method | pH; preparation conditions | Use comparable conditions for solution measurements. |
| Insolubles and dissolution | Insolubles method and mixing conditions | % or stated method; time and temperature | Residual material or incomplete dissolution can affect handling. |
| Physical form and purity | Form, particle requirements and relevant contaminant limits | Declared form; units for each limit | Qualify the source and process fit separately. |
Frame the mineral-management question
Describe the system: Describe the food matrix, water/mineral conditions, protein content, pH, heat history and the problem being observed.
Observe in a controlled trial: Compare clarity, sediment, dispersion or texture as relevant to the food. Keep the recipe and processing conditions constant; a useful result in one system does not establish universal stability.
A trial informs selection for that material and process; it is not a guarantee for a different grade or future batch.
PURCHASING QUESTIONS
SHMP: what to ask next.
Does the name identify one molecular composition?
Do not assume that it does. Request the source’s commercial identity and composition information. The published glassy-polyphosphate identity is a reference, not a specification for a particular offer.
What makes a pH comparison useful?
Use matching concentration, water, preparation and temperature, and note the method and document revision. An unqualified pH number cannot resolve a grade comparison.
When should I compare SHMP with STPP?
When both are candidates for the same stated problem. Test mineral interactions, dispersion or water-management objectives in the actual food rather than declaring either universally better.
Packaging, handling & ordering
Include your dissolution step and water conditions in the inquiry. Ask for the pack format and source-specific storage and shelf-life information alongside the selected grade.
Share your quantity and required delivery timing. Minimum order, sample terms, packing and the stated shelf life belong to the specific quotation and source records.
Identity reference points
These sources support technical identity checks. They do not establish a supplied grade, source approval or permission in every food or market.
DOCUMENT REQUEST
Request documents for SHMP.
Tell us the material form, intended use, destination market and document purpose. Request Current specification, representative COA and composition, pH or dissolution test information. Records depend on the proposed grade and source; any certificate applies only within its stated entity, site and product scope.
