Ingredients in food are generally derived from particular plants or animals. Last year, I scraped the first 90,000 foods in OFF API for the taxonomic species/genus/family name of ingredients for the phylogenetic food visualization at https://observablehq.com/@thadk/life diagram (switch to "Fit to Size: Width" and "OpenFoodFacts Ingredients (first 90k)").

Unfortunately, only a small fraction had that property filled in. Is there a better source for taxonomic names in foods? For instance, I don't see it in UM-NCC sample files.
