Sorbic acid dispersion and preservation
Sample multiple points at the actual oil-to-water ratio and temperature. Check dispersion and storage stability.
Oil-water blending
Fix oil-to-water ratio and mixing procedure. Test top, middle and bottom samples and observe after cooling.
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 · Sorbic Acid product information ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Assay | % on a dry basis | ENVO published specification 99.0–101.0% | Specify the drying and assay methods. Distinguish the free acid from the potassium salt. |
| Moisture | % by mass | ENVO published specification ≤0.5% | Check the inner bag seal when sampling. Test dispersion uniformity separately in the actual formulation. |
| 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.
Chemical identity
| Database entry | Molecular or composition formula | Molar mass |
|---|---|---|
| Sorbic Acid | C6H8O2 | 112.13 g/mol |
The values refer to the compound indicated. Confirm hydrate form, solution concentration and blend composition for the commercial grade.
From samples to commercial delivery
Packaging and receiving
ENVO lists 25 kg bags or cartons. Confirm net weight, units per pallet and label revision.
Storage and handling
For bagged or boxed powder, verify size grade, moisture and closure. Protect retained samples against moisture change.
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 does sorbic acid deposit and become uneven within the batch?
Sample several positions at the actual oil-to-water ratio and temperature. Check dispersion and storage stability.
Does a clear stock solution establish uniformity throughout the finished product?
Sample several locations at final pH, temperature and oil-to-water ratio. Track precipitation during storage.
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 Assay, particle distribution, system acidity.
