The following two tables list all of the specifications for food additives (Table 1) and flavourings (Table 2) adopted by reference by the Commission as well as their initial year of adoption and years of subsequent adoptions of revisions. Years in brackets indicate adoption of revised limits for arsenic and heavy metals, only; these limits supersede those in the full specification monograph adopted in an earlier-cited year. Those substances recognized as having both flavouring and non-flavouring functionality are listed in both tables. In some instances, the year of adoption of the specification for the flavourings will differ from the year of adoption of the specification for the non-flavour application.
