Data Sources

Primary source: OpenFoodFacts

OpenFoodFacts provides the base catalog for product metadata including ingredients, nutrition fields, and product attributes used for barcode resolution.

Internal processing pipeline

• Ingredient normalization for messy labels and OCR artifacts.
• Deterministic scoring and confidence rules for consistent outputs.
• Cache-aware backend processing for repeated scans.

Data quality caveats

Product records can be stale or incomplete, and manufacturers may change formulation over time. Nuli continuously updates scoring and confidence logic, but users should always verify package labels.
