A summary follows of the Committee's evaluations of technical, toxicological, and intake data for certain food additives (annatto extracts, natamycin, propyl paraben, synthetic lycopene and lycopene from Blakeslea trispora, and quillaia extract type 2) and food contaminants (aluminium, 3-chloro-1 2-propanediol, 1 3-dichloro-2-propanol, and methylmercury).
