Plan a trial for your application
Low-protein diet evaluation
Under the same dietary constraints, evaluate the L-isoleucine contribution and recheck other branched-chain amino acids.
Lot substitution
Verify that the method resolves isoleucine from leucine. Then compare particle size and as-received assay.
Purchase specifications and incoming inspection
Review these properties when selecting and inspecting incoming material. Example figures refer to the cited grade or source. Confirm the offered specification, packaging and lead time in the quotation. CJ BIO BestAmino · L-amino acids for feed ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| L-Isoleucine | % as received | Confirm for the proposed grade and project | Use an analytical method specific to the L-amino acid. State whether the result is expressed as free base, salt or as-received product. |
| Stereochemistry | Identification result | Confirm for the proposed grade and project | Request identity evidence for the L configuration or the specified optical rotation conditions, matched to the sample lot. |
| Particle size | µm / % sieve residue | Confirm for the proposed grade and project | Report sieve apertures and percentage passing. Make a composite sample from different bag positions and distinguish lumps from primary particles. |
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
Identify L-isoleucine separately to prevent accidental dispatch of L-leucine.
Storage and handling
Match commercial lot and size grade. Check feeding and weighing errors if moisture causes agglomeration.
Sample and order lead times
State premix or pelleting trial size, replenishment quantity and receiving warehouse. Confirm MOQ, preparation time and plant arrival separately for samples, pallets and split orders.
Questions from the plant
Can a lot be released when two branched-chain amino acid peaks overlap?
Request a method and report that distinguish the target component. Confirm against the retained sample.
Should a replacement use the same number of kilograms?
Convert using measured isoleucine, then verify blend uniformity on the intended equipment.
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 L-Isoleucine, Stereochemistry, Particle size.
