Trace every ingredient lot through kettle, filler and carton to the retailer’s dock.

Every pack carries a best before date, a batch code and an ingredient list, and all three must be right. A missing lot code or a stale allergen line stops a pallet at the retailer’s dock and can open a recall. The bill comes later.

Batch and traceability records join each ingredient lot to the finished carton, through the kettle, the filler and the coder. One search then shows where a lot code or temperature log goes missing between the goods inward bay and the retailer’s delivery note.

Flour, oils, spice blends, sorbate and printed film arrive from approved suppliers and are held by lot, with a certificate of analysis where the ingredient needs one. Planning schedules batches by recipe and line, and one short roll of printed film can hold back a whole day of filling. Operators weigh each ingredient to the recipe, then cook in a jacketed kettle, blend or bake, and chill the product to core temperature before the filler. Sealers, labellers and coders run at set speeds, while checkweighers reject underfilled packs and a metal detector with a reject arm catches stray steel. Each pack is inkjet coded. The line sheet records cook temperatures, hold times, brix readings and any rework, and a supervisor signs it before the batch moves to the store. Finished goods wait in racking until released.

Retail chains, distributors and food service buyers order by the pallet, and each wants its own code format printed on the carton and quoted on the delivery note. Many also want allergen sheets and lot codes. A complaint or a recall query reaches the quality manager’s desk with a buyer already waiting for an answer. Any gap slows it. Trust suffers.
