Link the sample to the process
Record fruit lot, fresh/frozen/prepared condition, extraction route, any conditioning, sample temperature and the sampling point. Keep paired inlet, product and reject samples where available. Do not identify a layer by colour alone.
Observe phases under the same conditions
Use the same container, fill height, standing time and temperature. Record mixing before sampling, cream-layer height, serum appearance and sediment separately. Retain dated photos with a scale and the sample ID. Natural layering can be relevant to the product specification.
Connect the observation to an outlet
State which stream should remain in the ingredient and which should be collected separately. A bench layer is not proof that a selected separator has a dedicated outlet or reaches a recovery specification.
