就(EC)No1333/2008附件二和附件三列表中甜菊糖苷（E960）的规格，修订法规(EU) No 231/2012 附件

(1)

Commission Regulation (EU) No 231/2012 ( 3 ) lays down specifications for food additives listed in Annexes II and III to Regulation (EC) No 1333/2008.

(2)

Those specifications may be updated in accordance with the common procedure referred to in Article 3(1) of Regulation (EC) No 1331/2008, either on the initiative of the Commission or following an application.

(3)

On 13 November 2013 an application was submitted for the amendment of specifications concerning the food additive steviol glycosides (E 960). The application was made available to the Member States pursuant to Article 4 of Regulation (EC) No 1331/2008.

(4)

The current specifications stipulate that steviol glycosides (E 960) preparations contain not less than 95 % of ten named steviol glycosides: stevioside, rebaudiosides A, B, C, D, E and F, steviolbioside, rubusoside and dulcoside, on a dried basis. The specifications further define the preparations/final product consisting mainly (at least 75 %) of stevioside and/or rebaudioside A.

(5)

The applicant requests that rebaudioside M is added to the list of permitted steviol glycosides as an additional glycoside that may comprise the assay value of not less than 95 % (total steviol glycoside content). The applicant also requests that the minimum amount of 75 % of stevioside and/or rebaudioside A is deleted, i.e., to change the ‘Definition’ of steviol glycosides.

(6)

The applicant further requests to expand the lists of chemical names and molecular weights and CAS numbers to include, in addition to stevioside and rebaudioside A, the other nine steviol glycosides. Rebaudioside M should also be added to the listing of molecular formulas. To account for the greater sweetness potency of rebaudioside M, the ‘Description’ of steviol glycosides should be amended.

(7)

Since stevioside and rebaudioside A may not necessarily be the principal steviol glycosides, the stevioside and rebaudioside A criterion under the ‘Identification’ of steviol glycosides should be removed from the specifications.

(8)

According to information provided by the applicant, a production process has been developed which allows for the selective isolation of rebaudioside M resulting in the production of steviol glycosides preparations enriched in rebaudioside M specifically, at a range of concentrations (from 50 % up to nearly 100 %). According to the applicant, only leaves of the Stevia rebaudiana Bertoni plant comprise the starting material for the production of steviol glycoside extracts containing at least 50 % rebaudioside M. Its manufacturing process is similar to the general method of extracting steviol glycosides from the leaves of S. rebaudiana which has been previously reviewed by EFSA in 2010 ( 4 ) .

(9)

In the new production process, the crushed stevia leaves are extracted with hot water and the resulting extract is subjected to isolation and purification (by use of ion-exchange chromatography). This initial stage is followed by additional purification steps, including further and repeated recrystallisation and separation steps. Through the manipulation of these purification steps (i.e. specific number of crystallisation steps, solvent concentration, as well as temperature and duration of the process) the manufacturer is able to selectively crystallise a preparation high in rebaudioside M. Also, the production process involves use of solvents (ethanol and methanol) that are currently recognised for use in the manufacture of steviol glycoside preparations.

(10)

That production process results in a preparation that contains 95 % of steviol glycosides with rebaudioside M representing more than 50 % of the finished product and the remainder comprising the following ten related steviol glycosides in any combination and ratio: stevioside, rebaudiosides A, B, C, D, E, F, dulcoside, steviolbioside and rubusoside. While extracts characterised by a ≥ 95 % content of rebaudioside M contain < 5 % of rebaudiosides D, A and B combined, extracts with a lower rebaudioside M content (approximately 50 %) may comprise close to 40 % rebaudioside D and 7 % rebaudioside A.

(11)

In its opinion ( 5 ) of 8 December 2015 the European Food Safety Authority (‘the Authority’) concluded that extending the current specifications to include rebaudiosides D and M as alternatives to rebaudioside A in the predominant components of steviol glycosides would not be of a safety concern. The Authority also concluded that provided that the total amount of steviol glycosides (stevioside; rebaudiosides A, B, C, D, E, F and M; steviolbioside; rubusoside and dulcoside) were greater than 95 %, which are all converted to steviol, and given that there was no evidence of absorption for intact glycosides at realistic use levels, the specific steviol glycosides (E 960) composition would not be of a safety concern. It was also considered that the ADI of 4 mg/kg bw/day (expressed as steviol equivalents) can also be applied where total steviol glycosides (stevioside; rebaudiosides A, B, C, D, E, F and M; steviolbioside; rubusoside and dulcoside) comprise more than 95 % of the material.

(12)

Taking into account the submitted application and the evaluation made by the Authority, it is appropriate to amend the specifications of the food additive E 960.

(13)

Regulation (EU) No 231/2012 should therefore be amended accordingly.

(14)

The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on Plants, Animals, Food and Feed,
