Call for technical data on sucralose (E 955)

EFSA-Q-number: EFSA-Q-2011-00724

  • Published: 22/11/2021
  • Deadline for registering interest: 22/12/2021
  • Deadline for submission of data: 22/02/2022


Pursuant to Article 32(1) of Regulation (EC) No 1333/2008[1], food additives which were permitted for use in the European Union before 20 January 2009 need to be re-evaluated by the European Food Safety Authority (EFSA). The programme for this re-evaluation is defined by Commission Regulation (EU) No 257/2010[2].

In accordance with the above regulations EFSA started a systematic re-evaluation of authorised food additives and is issuing scientific opinions on these food additives, according to the priorities indicated in the Regulation (EU) No 257/2010, which foresees in article 3(b) that “the re-evaluation of all approved sweeteners listed in Directive 94/35/EC shall be completed by 31 December 2020”.

In accordance with Article (5) of the Regulation (EU) No 257/2010, EFSA has already made open calls for data for the sweeteners under the re-evaluation programme[3],[4]. On the basis of the information received from interested parties and those retrieved from the literature EFSA has started the assessment of these food additives.

As recorded in the minutes of the 33rd meeting[5] of Sweeteners Re-evaluation Working Group of the Food Additives and Flavourings (FAF) Panel and 24th plenary meeting of FAF Panel[6], during the course of the preliminary assessment of the available data, the need for additional information considered to be relevant for the re-evaluation has been identified for sucralose (E 955).

Therefore, in accordance to article 6(3) of the Regulation (EU) No 257/2010, EFSA launches a public call for data in order to acquire documented information (published, unpublished or newly generated) on sucralose (E 955).

EFSA will consider the relevance of the information provided for the risk assessment of these food additive. The submission of the requested information is without prejudice to the final opinion of the FAF Panel.

Overall objective

The purpose of this call for data is to offer to interested parties and/or stakeholders the opportunity to submit documented information (published, unpublished or newly generated) relevant to the re-evaluation of sucralose (E 955).

Deadline for submission of data and disclosure of contact details

Interested parties and stakeholders should provide by 22/02/2022 the information described below.

Within 4 weeks from the publication of this call, please communicate in writing by e-mail to: fip [at], your availability to submit the requested information by the timeline specified above or any proposal for a new deadline providing justified reasons. Depending on the replies received the final deadline will be communicated to you through e-mail and by updating the current call.

In accordance with Article 6(4) of the Regulation (EU) No 257/2010 any information not submitted within the final deadline shall not be taken into account in the re-evaluation. However, in exceptional cases, EFSA may decide with the agreement of the Commission to take into account information submitted after the deadline, if that information is significant for the re-evaluation of a food additive.

In order to facilitate the collaboration of all interested parties to provide the data needed, we are seeking your consent to disclose your personal data (name, e-mail address and telephone number) to the other parties that have expressed an interest to provide the requested information. If you do not wish to make your contact details available, clearly indicate it in your first communication.

Information sought

EFSA kindly invites business operators and other interested parties (governments, interested organizations, universities, research institutions, companies) to submit information on the following food additives:


E number


E 955

  1. Data and information on manufacturing process

A preliminary assessment of the available data and information on the manufacturing process of sucralose (E 955) was conducted by the WG on Sweeteners Re-evaluation of the FAF Panel. This assessment has highlighted the need for collecting additional data and information on production method(s) applied to manufacture E 955.

Therefore, pursuant to article 6(3) of Commission Regulation (EU) No 257/2010, EFSA seeks additional data and information on manufacturing process(es) which is(are) currently in place to produce sucralose to be used as the food additive E 955. This information is used in the risk assessment to identify possible remaining impurities in the food additive (e.g. reaction intermediates, precursors, residual solvents, toxic elements).

Sucralose (E 955):

EFSA invites the interested business operators and other interested parties to:

  • provide detailed information on any production method used to manufacture E 955;
  • propose a short description of each production method used to manufacture E 955, including the key steps involved, for possible inclusion in the EU specifications of E 955;
  • provide analytical data on the identity and content of any impurity derived from each production method used to manufacture E 955 in preferably at least five independently produced batches of the food additive, using appropriate analytical methods applying state of the art techniques. The results of the analyses should be supported by certificates of analysis. In addition, information on the representativeness of the tested batches should be provided. Specific data on the methods of analysis used should be provided, e.g. the principle and scope of the method (i.e. the range of sample types that the method is used for), the concentration units used to express the analytical result(s), validation parameters of the method (in particular limit of detection (LOD) and quantification (LOQ));
  • provide the lowest technologically achievable levels for any impurity derived from each production method used to manufacture E 955.


According to article 8 of Regulation (EU) No 257/2010 setting up a re-evaluation programme of approved food additives, confidential treatment may be given to information the disclosure of which might significantly harm the competitive position of business operators or other interested parties.

Therefore, the business operators and/or the interested parties should indicate which information they wish to be treated as confidential and provide verifiable justification supporting this request. Please also note that the information described in Article 8(2) of Regulation (EU) No 257/2010 cannot be regarded as confidential in any circumstances.

In application of Article 8(4) of Regulation (EU) 257/2010, following a proposal from EFSA, the Commission will decide after consulting the interested business operator and/or the other interested parties, which information may remain confidential.

Submission of information

Interested business operators and/or interested parties should submit the information to EFSA through their chosen internet-based software (submission by email is not allowed) with a
