Plan a trial for your application
Stabilization of acidic beverages
Hydrate fully at actual pH and salt concentration. Compare viscosity, settling and mouthfeel.
Dry premix feeding
At the actual premix ratio, disperse, sieve and weigh unhydrated particles. Record time to stable viscosity.
Purchase specifications and incoming inspection
Include the intended grade or current specification in the enquiry. Use the table to compare selection criteria and inspection conditions. The specification agreed by both parties defines the contractual limits. ENVO · Sodium Carboxymethylcellulose (CMC) product information ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Degree of substitution | Dimensionless | JECFA monograph identity range: 0.20–1.50. | The range describes substance identity. Agree the target grade range and viscosity under specified conditions in the contract. |
| Viscosity under specified conditions | mPa·s | Request the grade-specific range | Fix solution concentration, temperature, hydration time, instrument and rotational speed. |
| Moisture | % by mass | Agree for the specific grade | Specify the water test, sampling and sealing conditions. Interpret water content and loss on drying separately. |
When approving a sample, record the grade, methods, limits and specification revision. On receipt, match the packing lot number to the lot-specific COA and record the measured values and release decision.
From samples to commercial delivery
Packaging and receiving
ENVO lists 25 kg bags. Confirm order-specific net weight, units per pallet and label revision.
Storage and handling
Check the viscosity grade and lot on the receiving label. Keep a sealed control after opening.
Sample and order lead times
State food category, sales market, pilot quantity and required arrival date. Confirm MOQ, batch documents, availability and remaining shelf life separately for samples and commercial orders.
Questions from the plant
Why do identical COA viscosity values give different suspension in a beverage?
Hydrate fully at actual pH and salt level. Compare viscosity, settling and mouthfeel.
Why does the screen block on scale-up when the bench sample is smooth?
Sieve samples at several times after addition using the same aperture. Distinguish poor initial wetting from excessive final viscosity.
Report a delivery or batch issue
Include the order number, lot number from the package, label photos and inspection records for the affected lot. When retesting, check Degree of substitution, viscosity test concentration and spindle, Moisture.
