Commission Regulation (EU) No 231/2012 of 9 March 2012 laying down specifications for food additives listed in Annexes II and III to Regulation (EC) No 1333/2008 of the European Parliament and of the Council (Text with EEA relevance)
Pan adawodd y DU yr UE, cyhoeddodd legislation.gov.uk ddeddfwriaeth yr UE a gyhoeddwyd gan yr UE hyd at ddiwrnod cwblhau’r cyfnod gweithredu (31 Rhagfyr 2020 11.00 p.m.). Ar legislation.gov.uk, mae'r eitemau hyn o ddeddfwriaeth yn cael eu diweddaru'n gyson ag unrhyw ddiwygiadau a wnaed gan y DU ers hynny.
Mae legislation.gov.uk yn cyhoeddi fersiwn y DU. Mae EUR-Lex yn cyhoeddi fersiwn yr UE. Mae Archif Gwe Ymadael â’r UE yn rhoi cipolwg ar fersiwn EUR-Lex o ddiwrnod cwblhau’r cyfnod gweithredu (31 Rhagfyr 2020 11.00 p.m.).
