Toxicological monographs are now available from JECFA’s 77th meeting in Rome (held in June 2013). The main points to note are outlined below:

  • an acceptable daily intake (ADI) of 5 mg/kg bw was assigned to advantame, based on maternal toxicity in a developmental toxicity study in rabbits
  • due to its low toxicity and low estimates of dietary exposure, an ADI “not specified” was established for glucoamylase from, and expressed in, Trichoderma reesei
  • the temporary group ADI of 12.5 mg/kg bw for glycerol ester of gum rosin and glycerol ester of wood rosin (GEWR) was withdrawn, and an ADI of 25 mg/kg bw was re-established for GEWR
  • for nisin, the previous ADI of 33,000 units/kg bw [40 units = 1 µg] was withdrawn and an ADI of 2 mg/kg bw was established based on the results of a 13-week toxicity study in rats
  • the temporary ADI “not specified” was retained for octenyl succinic acid modified gum arabic, pending submission (by the end of 2013) of additional data on its stability in food
