Plan a trial for your application
Clear calcium beverages
Request the lot assay basis. Check the target beverage after heating and after refrigeration.
Dilution of calcium concentrates
Record calcium concentration, turbidity and standing time before and after dilution. Check for precipitation after cold-chain storage.
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 · Calcium lactate gluconate product information ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Calcium content | % as received | ENVO published specification 12.5–13.5% | Confirm the composition of the mixed calcium salt and whether the assay is reported as received. |
| Moisture | % by mass | Agree for the specific grade | Specify the water test, sampling and sealing conditions. Interpret water content and loss on drying separately. |
| Test solution pH | Dimensionless | ENVO published specification 6.0–8.0 | Use a 5% cold solution at 20°C. Evaluate the finished product’s buffer system 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 woven bags with plastic liners. Confirm net weight, units per pallet and label revision.
Storage and handling
Check the ingredient composition and production lot. Confirm the moisture barrier and expected consumption per opened bag.
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
How can we identify the calcium contribution when several organic salts have similar names?
Request the batch calculation basis. Check the intended beverage after heating and refrigeration.
Can a blend of calcium lactate and calcium gluconate use the original sample approval?
Verify the composition ratio and compare dissolution and storage stability at equal calcium and temperature.
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 salt composition statement, elemental calcium content, Moisture.
