Plan a trial for your application
Potassium salt buffers
Calculate potassium and acid equivalents separately. Compare acidity and flavor in the actual formulation.
Balancing potassium contribution and tartness
Run trials against both potassium and finished-acidity targets. Record the formulation range that satisfies both.
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 · Potassium Malate product information ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Potassium content | % as received | Request the specification for the exact salt form. | Identify the acid salt or other form and the stereochemistry of malic acid. Do not convert based on the name alone. |
| Optical or chiral identification | Identification result | Confirm the agreed stereoisomer. | Use an accepted reference material or identical optical rotation conditions. Compare with an approved sample of the target configuration. |
| Buffering performance | pH versus acid addition | Approve in the target formulation | Plot comparison curves using the same acid, order of addition, solids and temperature. |
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 1 kg bags or 25 kg drums. Confirm order-specific net weight, units per pallet and label revision.
Storage and handling
Specify the potassium salt and lot on the packaging. Check seals on small packs and full drums separately.
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 can similarly named potassium malates give different potassium and buffer contributions?
Calculate potassium and acid equivalents separately, then check acidity and flavour in the intended recipe.
How should quotations for potassium malate be compared?
Request potassium mass fraction, hydrate form and net delivered price. Compare cost per unit of effective potassium.
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 Potassium content, salt form and stereochemistry, Solution pH.
