2021年1月27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）研究小组就低聚半乳糖（galacto oligosaccharides）作为新型食品使用条件变化的安全性发表科学意见。
经过评估，专家组得出结论，在拟议的使用条件变化下，建议增加食品补充剂中低聚半乳糖的最大含量是安全的。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 change in the conditions of use of galacto oligosaccharides (GOS) as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is mainly composed of GOS, consisting of different galactosyl residues (two to nine) linked to a terminal glucose by a β glycosidic bond but also contains lactose and its monomers (galactose and glucose). The NF is a syrup containing ≥ 55% GOS (w/w dry matter) and is produced enzymatically by two β galactosidases. GOS produced by β galactosidases according to the same production process is already authorised and included in the EU unio list of novel foods. This application is limited to an assessment of the proposed increase of the use level as food supplement. The proposed change in the conditions of use increases the maximum level in food supplements from 0.333 kg GOS/kg food supplement (33.3%) to 0.450 kg GOS/kg food supplement (45.0%). Since it is recommended that inpiduals consume no more than 3 servings of 12 g/day, the maximum recommended daily intake would be no more than 16.2 g GOS. No new food uses or other increases to the already approved use levels are being proposed. The information provided on the proposed use levels and anticipated intake do not raise safety concerns. The Panel concludes that the proposed increase in the maximum level of galacto oligosaccharides as a NF in food supplements is safe under the proposed changes in conditions of use.
