Score history across model versions
The score shown above is always computed with the latest published model. Earlier scores are kept for the record and are never edited or deleted; a scoring change ships as a new model version with a public write-up on the methodology page.
Nutritional: declared analysis vs reference ranges
Not applicable to complementary food. FEDIAF reference ranges apply to complete diets.
Transparency: what the label discloses
How much the manufacturer discloses, measured against the FEDIAF Code of Good Labelling Practice and Regulation 767/2009. Mandatory items dominate the weighting.
| Item | Points |
|---|---|
| Ingredient list on the label (mandatory) | 10/10 |
| Printed percentages on the label (voluntary) - not on file | 0/20 |
| Analytical constituents declared (mandatory) - not on file | 0/15 |
| Additives declared (mandatory) | 5/10 |
| Energy value declared (voluntary) - not on file | 0/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) | 10/10 |
| Manufacturer identity and address (mandatory) | 5/10 |
| Country of manufacture stated (voluntary) | 10/10 |
| Batch and date labelling (mandatory) - not on file | 0/5 |

Evidence: what the brand claims, and what supports it
The claims made on the pack and product page, checked against the declared label. We record claims as stated; "consistent" means our stored label data supports the claim, "contradicted" means it conflicts with it. Functional claims are recorded but never scored.
