The moment guava pulp leaves the refiner, its identity starts to depend on records rather than on appearance. A beverage-base line adds water, ingredients and transfers that can obscure where a lot came from. A practical lot record keeps the pulp batch, the recipe and the sanitation evidence connected from refining through to the declared product handover.
Open the record at the pulp batch
Give the extracted pulp a batch identifier and attach the source lot. Record the cultivar or blend where known, the extraction date, the preparation route, the screen fitted to the pulper, the operating condition and any treatment or storage before blending. If the pulp arrived from another plant, record the supplier, the incoming container, the stated prior process and the receiving temperature. Do not assume that a purchased pulp has the same history as pulp made on the same site.
The batch record should also describe the condition that matters downstream: visible seed fragments, gritty texture observations, fibre and body, and any measured solids or acidity with method. These are the characteristics that a blender may need to adjust for, and they are also the characteristics that a buyer may ask about later. A batch number without a description is an index, not a specification.
Treat water and ingredients as declared inputs
In a formulated beverage base, water is an ingredient, not a harmless filler. Record its source, the treatment or sanitary condition relied on, and the quantity added to the batch. Record each other ingredient with its lot or delivery reference, the measured amount and the addition order. The recipe establishes the product boundary; the fruit fraction and the total batch volume should be stated separately so that added water is not mistaken for additional fruit extraction.
This boundary has regulatory significance in some markets. FDA's juice HACCP guidance defines juice to include purees of edible fruit portions and concentrates, and it distinguishes a juice ingredient from a beverage that contains less than 100 percent juice. The exact labelling and HACCP obligations depend on the product and jurisdiction. Keep the product description, the recipe and the juice-content basis together, and obtain competent regulatory advice for the destination market rather than inferring a claim from a machine name.
Trace every buffer transfer and line clearance
Record each transfer from the pulp buffer to the blending tank: source tank, destination tank, start and end time, product temperature where relevant, transfer route and the person or system responsible. If a transfer is interrupted, note the hold period and what happened to the material. A buffer is an operating interface, not a place where lot identity can be allowed to disappear.
Line clearance matters when the same circuit handles more than one recipe or product. Record the cleaning and rinse step between batches, the valves or branches included, and the check that the route was actually clear before the new batch started. A shared manifold that is not positively identified can create an unintended mix even when each tank carries a correct label. Product-contact surfaces, seals and low points deserve a defined cleaning boundary between recipes.
Keep quality and sanitation evidence together
A blended base should have a release record that connects the pulp batch, the ingredient lots, the blend record and the treatment or filling handover. Include the samples taken at named points, the results and the disposition of any nonconforming material. If a result is outside the agreed limit, record the decision and the affected quantity; do not let a later good result erase the earlier deviation.
FDA's juice HACCP guidance describes hazard analysis, critical limits where applicable, validation, verification and record keeping, and it expects validation by a trained or qualified person. That is a regulatory framework, not a certificate for a machine. A thermal system, a holding tube or a filling head does not by itself prove that a preservation process is validated for a particular guava base and package. Keep the process authority's basis, the operating records and the verification records together so the lot can be reconstructed.
Close the lot at the declared product boundary
At the end of the run, state exactly what left the line: unformulated guava pulp, a formulated beverage base, a treated bulk bag or an intermediate at a named filling handover. Record the quantity, the package or container identifiers, the date and the destination. If the product is a base for another plant, say so plainly; a bulk base is not retail packaging and does not become one merely because a filler is nearby.
The final record should let a reviewer follow one pulp batch through blending, treatment, filling and storage without relying on memory. That is the practical meaning of traceability in a guava project: not a software label, but a chain of identified material, declared inputs, verified cleaning and released results. When the chain is complete, a buyer question about a single bag can be answered from records rather than from a search through the plant.
