• jecfa_by_functional_class ~227 tokens
  List every substance JECFA has evaluated in one functional class — sweeteners, preservatives, colours, emulsifiers, antioxidants and so on — or every substance in one of the four groups: food_additives, flavouring_agents, food_contaminants, veterinary_drugs. Each entry carries its ADI and CAS number
• jecfa_by_number ~123 tokens
  Resolve a FEMA number or a JECFA substance number to its evaluated substance. These identifiers appear in flavouring literature and JECFA meeting reports. For INS/E-numbers use jecfa_search instead.
• jecfa_chemical ~181 tokens
  Fetch the complete JECFA record for one substance by its chemical id: chemical and synonym names, CAS and INS numbers, functional class, and every safety evaluation JECFA has made of it — evaluation year, ADI, the committee’s conclusions, dietary exposure findings, meeting number, and the TRS report
• jecfa_functional_classes ~128 tokens
  List the JECFA functional-class vocabulary — the 71 technological purposes a substance can be evaluated under (sweetener, emulsifier, antioxidant, humectant…), grouped into food additives, flavouring agents, food contaminants and veterinary drugs. Call this to discover the exact class name that jecf
• jecfa_recent_evaluations ~92 tokens
  Show the substances most recently added or re-evaluated by JECFA, with their current ADI and functional class. Use to check what the committee has looked at lately rather than to look up a known substance.
• jecfa_search ~229 tokens
  Look up a food additive, flavouring, contaminant or veterinary drug in the WHO/FAO JECFA database by substance name, CAS number, or INS/E-number (E951, INS 951, 160a). Returns the Acceptable Daily Intake (ADI), CAS number, functional class and a chemical id for fetching the full safety evaluation. U
