Plan a trial for your application
Iron sources for fortified beverages
At equal elemental iron, compare acidity, color and precipitate during storage.
Iron salt substitution trials
Replace the existing iron source on a measured ferrous-iron equivalent basis. Compare clarity, color and mouthfeel.
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 · Ferrous Lactate product information ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Ferrous iron | % by mass | ENVO published specification ≥18.0% | The published table separately lists total iron ≥18.9%. Distinguish the two results on receipt. |
| Total iron | % by mass | ENVO published specification ≥18.9% | Compare with ferrous iron on the same as-received basis and record the method. |
| Dissolution or dispersion behavior | min or % residue | Verify under the approved sample conditions | Fix addition rate, water composition, agitation, temperature and standing time. Compare residue and precipitate. |
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
Verify hydrate and seal. Attach the as-received ferrous iron result to the ingredient release record.
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 did the iron dose change when replacing salts weight for weight?
Prepare trials at equal elemental iron. Compare acidity, colour and precipitation in storage.
Does a total-iron label establish the ferrous iron dose?
Request separate results and identify the hydrate. Calculate as-received ferrous iron before calculating the amount added per serving.
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 Elemental iron, ferrous iron fraction, water of crystallization.
