Key Gotchas

1. validate_ingredients is KEYWORD-ONLY -- detects literal words (eggs, milk, fish) but MISSES gluten-containing cereals (wheat, oat, rye, barley NOT detected as Allergen #1 Cereals containing gluten). Only the word 'gluten' itself triggers detection.
2. False positives from compound words -- 'cashew butter' triggers Milk allergen (#7) because 'butter' is a milk keyword. The tool has no semantic awareness.
3. Crustaceans and molluscs NOT detected -- 'shrimp', 'squid', 'oyster' not in keyword list; only 'fish' triggers Allergen #4.
4. Turkish/non-English ingredients NOT detected -- 'sut tozu' (milk powder), 'yumurta' (eggs), 'bugday gluteni' (wheat gluten) all return 0 allergens.
5. function_class accepts BOTH German and English -- 'Farbstoff' and 'Colour', 'Konservierungsmittel' and 'Preservative', 'Suessungsmittel' and 'Sweetener' all work.
6. Bilingual data -- all records have German (namede) and English (nameen) names, German function and English function_en.
7. 147 additives covering E100-E951+, with maxlevel (often 'quantum satis' = no limit) and foodsallowed.
8. 14 EU allergens with common_sources lists and EU regulation references.
9. Nutrition reference returns 13 nutrients (Energy through Potassium) per EU 1169/2011 Annex XIII Part A.
10. Nonexistent queries return empty array [] (no error); nonexistent function classes return helpful message listing available classes.
