aerobic：欧盟批准麦角硫因作为新资源食品配料

(1)

On 25 July 2013, the company Tetrahedron made a request to the competent authorities of France to place synthetic L-ergothioneine (‘L-ergothioneine’) on the Union market as a novel food ingredient within the meaning of point (c) of Article1(2) of Regulation (EC) No 258/97. The application excluded from the use infants, young children, pregnant and lactating women.

(2)

On 19 February 2015, the competent food assessment body of France issued its initial assessment report. In that report it came to the conclusion that L-ergothioneine meets the criteria for novel food ingredient set out in Article 3(1) of Regulation (EC) No258/97.

(3)

On 9 March 2015, the Commission forwarded the initial assessment report to the other Member States.

(4)

Reasoned objections were raised by other Member States within the 60-day period laid down in the firstsubparagraph of Article 6(4) of Regulation (EC) No 258/97.

(5)

On 14 October 2015, the Commission consulted the European Food Safety Authority (‘EFSA’) asking it to carry out an additional assessment for L-ergothioneine as novel food ingredient in accordance with Regulation (EC) No258/97.

(6)

On 26 October 2016, EFSA in its ‘Scientific Opinion on the safety of L-ergothioneine as a novel food pursuant to Regulation (EC) No 258/97’(2)concluded that L-ergothioneine is safe for the proposed uses and use levels.

(7)

That opinion gives sufficient grounds to establish that L-ergothioneine in the proposed uses and use levels complies with the criteria laid down in Article 3(1) of Regulation (EC) No 258/97.

(8)

Directive 2002/46/EC of the European Parliament and of the Council(3)lays down requirements on food supplements. The use of L-ergothioneine should be authorised without prejudice to the provisions of that Directive.

(9)

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