欧盟评估扩展使用2'-FL和LNnT作为新型食品用于婴儿食品补充剂中的安全性

2022年5月4日，据欧盟食品安全局（EFSA）消息，欧盟营养、新型食品和食物过敏源（NDA）研究小组就扩展使用2'-岩藻糖基乳糖（2'-FL）和乳糖-N-新四糖（lacto-N-neotetraose）（LNnT）作为新型食品用于婴儿食品补充剂中的安全性发表科学意见。

经过评估，专家小组得出结论，在建议的使用条件下，婴儿食用含2'-FL或LNnT的营养强化食品是安全的。部分原文报道如下：

Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on the safety of the extensions of use of the authorised novel foods (NFs) 2’-fucosyllactose (2’-FL) and lacto-N-neotetraose (LNnT) in food supplements (FS) for infants pursuant to Regulation (EU) 2015/2283. The NFs are produced by fermentation with genetically modified strains of Escherichia coli K-12 and already Ｉncluded in the EU list of NFs. The applicant stated that no changes in the production process or the identity of the NFs occurred. The applicant proposes an extension of use of the NF containing 2’-FL in FS intended for infants (< 1 year), at a maximum use level of 1.2 g/day. The applicant also proposes an extension of use of LNnT in FS intended for infants, at a maximum use level of 0.6 g/day. The intake of 2’-FL per kg body weight from the proposed maximum use levels in FS for infants is lower than the lowest estimated mean intake of naturally occurring 2’-FL from human milk. Similarly, the intake of LNnT per kg body weight is lower than the highest estimated mean intake of naturally occurring 2’-FL from human milk. Furthermore, the Panel notes that the proposed uses of 2’-FL in FS for infants are lower than the estimated intake from the already authorised uses of the NF for the same population group. The Panel also notes that the proposed uses of LNnT in FS for infants are similar to the estimated intake from the already authorised uses of the NF for the same population group. The Panel concludes that the use of the NFs containing 2’-FL or LNnT in FS for infants is safe under the proposed conditions of use.
