Selection overview
Food & Beverage Decolorization selection starts with operating data
Food and beverage decolorization should be qualified with the actual process liquid because color bodies, pH and dissolved solids can change adsorption and filtration behavior. Compare candidate PAC grades at equal dose and contact time, then confirm filtration, carryover and destination-specific documents for the selected grade.
Recommended sourcing direction
Wood based PAC, commonly 200 or 325 mesh, qualified by actual-liquid decolorization and filtration testing
The figures below are common sourcing references, not an application-performance guarantee. Final grade, test methods and batch limits are confirmed after the operating conditions are reviewed.
| Common particle size | 200 or 325 mesh, specified with a minimum target passing rate |
|---|---|
| Methylene blue | Common target range: 150-200 mg/g |
| Iodine value | Typical supporting range: 800-1,050 mg/g |
| Ash | Common target: <=5-10% |
| Moisture | Typically <=5% |
| Application-specific checks | Caramel or molasses decolorization, iron, chloride, phosphate, filtration time and testing against the actual liquid |
Application data needed for grade matching
Liquid identity and composition, initial and target color, pH, dosage, contact time, temperature, filtration method, required documents, quantity and packing.
Qualification boundary
Confirm suitability with the actual system and agreed test method
Food-contact or drinking-water compliance is not a blanket product claim. Applicable documents and contaminant limits must be confirmed for the selected grade and destination market.
System qualification
Move from operating data to a defensible grade specification
The selection process separates system conditions from product properties so the quotation can state relevant tests and acceptance values.
Process factors to send
- Actual liquid composition, initial color and target color
- Dose, contact time, temperature and process pH
- Filter equipment, filtration time and acceptable carbon carryover
- Iron, ash, phosphate, chloride or destination-specific document limits
Recommended validation path
- Shortlist PAC by liquid chemistry
- Run equal-dose actual-liquid tests
- Compare color removal and filtration behavior
- Confirm grade documents and batch limits
Performance boundary: Operating results depend on the actual system. A sample or pilot result should use an agreed method and representative conditions.

Timing starts after the product specification, packing, order documents and agreed payment conditions are confirmed.
Export terms by route
Qingdao or Tianjin are commonly used; the final loading port is confirmed with the route and trade term.
FAQ
Food & Beverage Decolorization sourcing questions
Testing against the actual liquid is strongest. Methylene blue, caramel or molasses value, pH, ash, iron and filtration time help compare candidate grades.
PAC must be removed after adsorption. A high adsorption index can still be impractical if the carbon blinds filters, filters too slowly or creates unacceptable carryover.
Documents are reviewed for the selected grade and destination regulation. They are not assumed from a generic food or beverage application name.
