据了解，该6'-唾液乳糖钠盐是由大肠杆菌K-12 MG1655 (ATCC 700926)的衍生菌株(大肠杆菌K-12 MG1655 INB-6SL_02)生产的。经过评估，专家小组得出结论，在提议的使用条件下，6'-唾液乳糖钠盐作为新型食品是安全的。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 6′-sialyllactose (6’-SL) sodium salt as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is mainly composed of the human-identical milk oligosaccharide (HiMO) 6’-SL (sodium salt), but it also contains d-lactose, sialic acid, 6′-sialyllactulose and a small fraction of other related saccharides. The NF is produced by fermentation with a genetically modified strain (Escherichia coli K-12 MG1655 INB-6SL_02) of E. coli K-12 MG1655 (ATCC 700926). 6’-SL (sodium salt) produced by fermentation with genetically modified strains of E. coli K-12 DH1, E. coli BL21 or E. coli W is already authorised and included in the EU list of NFs. This application refers to a change in the production process and specifications, while the target population, conditions of use and consequently the anticipated intake remain unchanged. The information provided on the identity, production process, composition and specifications and the toxicological data of the NF do not raise safety concerns. The intake of other carbohydrate-type compounds structurally related to 6’-SL is also considered of no safety concern. In line with other HiMOs, the safety assessment of this NF is mainly based on the comparison between the intake of breastfed infants and the estimated intake of the NF. Given that the NF would be consumed to the same extent as the already authorised 6’-SL (sodium salt), the Panel considers that the consumption of the NF at the proposed uses and use levels does not raise safety concerns. The Panel concludes that the NF is safe under the proposed conditions of use.
