    • Barley

Objective

Analyze the list of product ingredients to establish whether:

  • the product contains gluten
  • the product may contain gluten
  • the product does not contain gluten

Identification

Using 3 lists of ingredients (contains, possibly contains, and does not contain gluten), we can analyze the list of ingredients, and thus identify the presence of gluten in the products.

Please note: the absence of gluten will only be possible for products where all the ingredients are present in the ā€œdoes not contain lactoseā€ list.

  • Ingredients containing gluten
  • Ingredients possibly containing gluten
  • Ingredients not containing gluten

In order to first sort the ingredients most present in the products, you can look at the list of all ingredients and sort it by number of products.

Uses

Indication of the presence or non-presence of gluten

In the product sheets on the site and on the mobile applications.

Search

Look for products without, with, or possibly containing gluten.

Would be nice to be able to search for products via a specific type of certification.

Notes

Technical aspects - GitHub

Apps based on Open Food Facts that have specific support for Gluten

  • Please list your app here :-)

Additional ideas

  • Improve support for cross-contamination with a knowledge panel giving the factory status, in addition to the ingredient detection. Eg: "Gluten-free from ingredients. Mention that the factory handles gluten." or: "Gluten-free certified. Verified gluten free from ingredients"
  • Add a way to search for foods with gluten certifications. Photos and information on the type of certification on the package can be available in the database.
