How Is Freshness Maintained During Manufacturing?
Once the ingredients pass screening, freshness is maintained through a few deliberate steps in how the cereal is made and packed:
- Heat treatment: High-temperature processing is used to keep the cereal free from microbes such as bacteria and viruses.
- Dehydration: Drying reduces the moisture content to a level where future bacterial growth is prevented. This is part of how the product manages a shelf life of around twelve months without preservatives.
- Oxygen removal during packaging: The air inside the sealed pack is replaced with a food-grade inert gas (nitrogen). This helps prevent oxidation and rancidity, keeping the product fresh and nutrient-dense without relying on chemical antioxidants.
Together, these three steps are what allow Nestlé to make CERELAC® with No Preservatives while still holding up on a shelf for several months, as long as the pack remains sealed. It's worth understanding why this combination works: bacteria and other microbes generally need moisture, oxygen and a hospitable temperature to grow. Removing these factors significantly slows down spoilage, and CERELAC®'s process is designed to address these issues at once, rather than relying on a single safeguard.
It's also worth keeping in mind that this shelf life applies specifically to the sealed, unopened pack. Once a pack is opened, the same protections, particularly the nitrogen environment inside, are no longer in place, which is why it matters to follow the storage guidance on the pack once it's been opened, and not assume the printed shelf life still applies in the same way.
For parents who want to verify this for themselves, Nestlé has built in a way to do exactly that: each pack carries a QR code that, when scanned, shows test results from independent, NABL-certified laboratories. This means the safety claims on the box aren't only a statement from the brand - they're backed by third-party lab data that you can look up yourself. NABL accreditation is a recognised mark of laboratory competence in India, which means the labs producing these results are themselves periodically assessed against international standards for testing and calibration. For a parent who wants more than a printed claim to go on, this is a fairly direct way to check the underlying data.
