Sterility testing
Container-closure integrity and incubation testing for canned, retorted, aseptic and vacuum-packed foods — the proof your seals hold.
What this service covers
Ambient-stable foods live or die by their seals. We incubate, inspect and challenge your packs so a swollen can or blown pouch never reaches a customer.
- Incubation and inspection of cans, jars, pouches and cartons
- Container-closure integrity: dye ingress and vacuum checks
- Thermophilic and mesophilic spoilage organism screens
- Seamer and process validation for new lines and formats
How sterility testing runs
Patient science for products measured in months, not days.
Step 1
Sample
Statistical sampling across seamer heads, retort baskets and production time.
Step 2
Incubate
Controlled incubation at mesophilic and thermophilic temperatures per protocol.
Step 3
Inspect
Seal examination, dye-ingress and vacuum testing on every suspect unit.
Step 4
Release
Sterility certificate with incubation data, ready for buyers and auditors.
Common questions
How many units do you need?
Depends on lot size and standard — typically 30–60 units covering all seamer heads and retort positions. We confirm the plan before you ship.
Can you validate a new packaging format?
Yes. Format changes, new seal materials and new retort profiles all get a full validation protocol with acceptance criteria agreed upfront.
What if a unit fails?
We isolate the failure pattern — seamer head, time window, position — and retest a focused sample so production restarts fast.
