  • 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

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

  • The ingredients are not yet taxonomized on Open Food Facts. They are taxonomized on 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 label

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

Notes:

  • The API returns all values in grams. This applies to both the key_100g and key_serving values.
  • The API always returns the energy values in kJ by default. Multiply the value by 0.23900573614 to convert it to Calories.
  • Any nutriments submitted to OFF as % DV values are converted to grams before being stored in the database. The conversion is done based on the values here. Thus, the conversion rates can be used again to change the nutriment values from grams back to % DV.
