Product images

  • Images ensure the reliability of Open Food Facts data. It provides a primary source and proof of all the structured data. You may therefore want to display it along the structured information.
  • We encourage you to let your users upload images for products that don't exist yet, and for existing products as well (packaging and information changes over time).
  • We have different scales of images. Use them wisely to save bandwidth, both for your users and Open Food Facts.
Raw images
  • image_small_url

Composition of a product : ingredients, detected ingredients, traces, allergens

Ingredients
Do not make the assumption that the ingredient is or is not present based on this. Parsing errors happen.
List of ingredients on a specific product
  • On a product ingredients_text contains the text of the ingredients.
    • ingredients_text_fr, ingredients_text_nl… (the package of a product may be multilingual)
    • ingredients_text_with_allergens_fr (same with HTML markup around allergens)
  • This list is parsed and we construct an ingredients and ingredients_tags list, but those will contain synonyms etc. We do not have a full taxonomy for ingredients yet. It's a work in progress.
    • ingredients
      • percent: possible detected percentage (still unreliable)
      • rank: the order of the ingredient in the ingredient list
      • id: a slug version of the detected ingredient
      • text: the raw text of the detected ingredient
    • ingredients_tags
  • The ingredients are not yet taxonomized on Open Food Facts. They are taxonomized on Open Beauty Facts
  • The taxonomies of ingredients need expansion: Global ingredients taxonomy (OFF), Global ingredients taxonomy Open Beauty Facts

==== Nutrition values ====
===== Nutrition data =====
====== General structure ======
The nutrition facts are presented by multiple fields per nutrition fact. Each nutrition fact is presented by a key, i.e. "salt", "fat", etc. The fields can also be found in the taxonomy translation file.

The fields can have the following structure:
* key (string) - the value for the nutrition fact key (eg in json: "fiber":"0.5");
* key_serving (string) -  the value of a serving for type key (eg: in json "carbohydrates_serving":"5.82"). The size of the servig is found in the serving field;
* key_value (string)  - the standardized value of a serving of 100g (100ml) for type key (eg in json: "salt_100g":"0.19");
* key_100g (string) - the standardized value of a serving of 100g (100ml) for type key (eg in json: "salt_100g":"0.19");
* key_unit (string) - the units used in the other fields (eg in json: "carbohydrates_unit":"g"). Possible values are "kg", "g", "mg, "µg", "l", "ml", "%" or "";
* key_label (string) - a more user friendly text explaining the 

Only the nutrition facts that are actually found on the packaging are present in the interface.
