Botanical identity and material
Confirm that the product is Moringa oleifera leaf powder and define whether stems, leaf fractions or other plant material are permitted.
Moisture
Moisture is an important quality and shelf-life parameter. The buyer should define a target or maximum and the test method used to report it.
Mesh and physical consistency
Mesh influences dispersion, mouthfeel and handling in many formulations. A sample should be approved against the same mesh requirement that applies to the production lot.
Colour and drying
Green colour can be a useful visual quality signal, but it should not replace analytical controls. Buyers should specify the acceptable colour range and, where important, the drying process.
Microbiology
For food and nutraceutical use, microbiological requirements should be agreed before production. Shipment-lot testing should use the buyer-approved laboratory or test method where required.
Packaging and storage
Use moisture-protective packaging suitable for the destination and expected storage conditions. The packaging specification should be included in the purchase order rather than left to assumption.
