Counts are distinct named ingredients from the ingredient lists in the LEON Foodie Fact Sheet and Barista Drinks Menu, September 2026 v1, issued 16 September 2026, including sub-ingredients, and are a minimum. Manufactured ingredients are those meeting NOVA group 4 criteria: substances not used in home cooking, and additives whose purpose is to make the final product palatable or stable. Emulsifiers, stabilisers, thickeners, preservatives, colours, added flavourings, acidity regulators, glucose syrups, dextrose, modified and refined starches, protein isolates and flour fortificants all count; milk, eggs, water, sugar and whole ingredients do not.
Additive class names are dropped and the named substance kept, and duplicates across components are counted once. Counts are automated from the published text and may differ slightly from a manual count. Drinks are not ranked here.
