Is your feature request related to a problem? Please describe.

We can easily compare nutrition facts for a set of products (with graphs, Nutri-Score etc.) but there is currently no way to compare their ingredients. For instance comparing the % of meat, milk, fruits, vegetables, added sugar etc. for a specific category of products.

The Project Recipes is to add features to do that, for research purposes (e.g. the makers of Agribalyse are very interested to have average recipes for categories of products, so that they can use those recipes to estimate the environmental impact of an average product), but also so that consumers and producers can quickly see how a product compares to others.

The basic features would be to select parent ingredients of interest (e.g. meat, fish, fruits etc.) and a set of products, and get information on the distribution of those parent ingredients for the set of products.

The information could be basic stats (mean, variance etc.) and distribution graphs.

We could also allow to see which products have the less or the more % of specific parent ingredients, and to compare a specific product with the average (like we have today for nutrition facts for products of the same category).

Describe the solution you'd like

The ingredients list is first analyzed with the Ingredients.pm module to identify each ingredient and estimate the percentage of each ingredient.

Then each ingredient is matched against the specified list of parents ingredients. (e.g. if we want the distribution of water, sugar and fruits, "apple" will be mapped to fruits.)

We can first implement the backend computations, make them available through scripts etc. and then build a web interface to integrate those functions with facets, graphs etc.
