The right process for your drink
Hot fill, cold fill, tunnel pasteurization, HPP, retort and aseptic each suit different drinks and give different shelf lives. Ask which processes the plant runs and which one it would use for your formula.
Filed processes for juice, acidified and low-acid drinks
Juice drinks fall under the FDA juice HACCP rule. Acidified drinks need a process reviewed by a process authority, and shelf-stable low-acid drinks, such as coffee with milk or protein shakes, need a scheduled process filed with the FDA. Ask who files and holds them.
A GFSI food safety certification
Retailers and distributors usually expect SQF, BRCGS or FSSC 22000. Ask for the current certificate and the result of the last audit.
Minimums that match your packaging
Run minimums depend on line speed, and printed cans often carry large minimums from the can maker. Ask who buys cans, ends, labels and trays, and whether they run labeled or shrink-sleeved cans for short runs.
Lot codes and best-by dates on every unit
Each can or bottle should carry a lot code and date you can trace back to ingredient lots. Ask how long they keep retained samples from each run.
Shelf-life testing
Flavor, color and carbonation drift over time. Agree on who runs the shelf-life study, what it measures, and what date goes on the label.
