Having regard to CouncilDirective 89/107/EEC of 21 December 1988
on the approximation of the laws of the Member States concerning food
additives authorized for use in foodstuffs intended for humanconsumption (
1), as amended by Directive 94/34/EC (2), and in particular
Article 3 (3) (a) thereof,
After consultation of the Scientific Committee on Food,Whereas it is necessary to establish purity criteria for all sweeteners
mentioned in European Parliament and Council Directive 94/35/EC of
30 June 1994 on sweeteners for use in foodstuffs (
3);
Whereas it is necessary to take into account the specifications and
analytical techniques for sweeteners as set out in the Codex Alimentarius
and the Joint FAO/WHO Expert Committee on Food Additives (Jecfa);
Whereas food additives, prepared by production methods or starting
materials significantly different from those included in the evaluation ofthe Scientific Committee for Food, or different from those mentioned in
this Directive, should be submitted for evaluation by the Scientific
Committee for Food with a view to full evaluation with emphasis on thepurity criteria;
Whereas the measures provided for in this Directive are in line with the
opinion of the Standing Committee on Foodstuffs,
HAS ADOPTED THIS DIRECTIVE:
Article 1

2. The purity criteria for E 420 (i), E 420 (ii) and E 421 mentioned in
the Annex to this Directive supersede the purity criteria for the said
substances mentioned in the Annex to CouncilDirective 78/663/EEC (
4).
Article 2
1. Member States shall bring into force the laws, regulations and
administrative provisions necessary to comply with this Directive not
later than 1 July 1996. They shall forthwith inform the Commissionthereof.
When Member States adopt these provisions, these shall contain a
reference to this Directive or shall be accompanied by such reference atthe time of their officialpubl ication. The procedure for such reference
shall be adopted by Member States.
2. Products put on the market or labelled before that date which do
not comply with this Directive may, however, be marketed until stocksare exhausted.1995L0031 — EN — 01.08.2001 — 003.001 — 2
