Overview of Canned & Retort Food Testing

Tested by: NABL-accredited partner lab
Regulation: FSSAI standards
Typical turnaround: 14–21 working days
Sample needed: 6–12 containers per batch

Canned and retort-pouch foods are sold at room temperature, so the process must destroy spoilage organisms and Clostridium botulinum, the cause of botulism. The commercial sterility test incubates sealed containers and then checks for swelling, pH change and microbial growth; it takes two to three weeks, which is why it is planned into production schedules.

Container checks cover vacuum, headspace and seal integrity. Food in tinplate cans is tested for tin and lead that may migrate from the can, and drained weight is checked against the label.

What the lab tests

Parameter	Why it is checked
Commercial sterility	Incubation at 37 °C and 55 °C followed by microbial checks
pH	Decides whether the product is a low-acid food needing a full sterilising process
Vacuum, headspace and seal integrity	Container soundness
Tin and lead	Migration from tinplate cans
Drained weight	Against the declared drained weight
Composition	Against the FSSAI standard for the product

The final list depends on your product, its standard and the purpose of testing. We confirm it with you before the sample goes to the lab.

Frequently asked questions

Why does sterility testing take so long?

Containers are incubated for 10–14 days so that any surviving organisms have time to grow and show up as swelling, pH change or microbial growth. The days of incubation cannot be shortened without weakening the test.

Will FSSAI and buyers accept the report?

Tests are done in labs accredited by NABL for the parameters reported, and for regulatory use in FSSAI-notified labs, which is what FSSAI, food safety officers and most buyers expect. For export, we match the lab to the importing country’s or buyer’s requirement.

Who carries out the testing?

Instacertify’s partner laboratories, accredited by NABL to ISO/IEC 17025 for the parameters on your report. We choose the lab, arrange the sample, follow up until the report is issued and explain the results to you.
