经过评估，专家小组认为该添加剂对目标物种、消费者和环境是安全的。由于缺乏数据，研究小组无法就该添加剂对皮肤或眼睛产生刺激的可能性得出结论。评估中的添加剂被认为是非反刍动物物种氨基酸L-缬氨酸的有效来源。为了使补充的L-缬氨酸对反刍动物和非反刍动物同样有效，需要防止其在瘤胃中降解。部分原文报道如下：

 

　　Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of l-valine produced by fermentation using a non-genetically modified strain of Corynebacterium glutamicum (CGMCC 18932). l-Valine is intended to be used in feed and water for drinking as a nutritional additive, functional group amino acids, their salts and analogues, for all animal species and categories. The production strain is considered suitable for the qualified presumption of safety (QPS) approach to safety assessment. The FEEDAP Panel concluded that l-valine produced by C. glutamicum CGMCC 18932 is considered safe for the target species when supplemented to the diet in appropriate amounts according to the nutritional needs of the target species. The use of l-valine produced using C. glutamicum CGMCC 18932 in animal nutrition is considered safe for the consumer and for the environment. No conclusion could be drawn on the potential of l-valine produced using C. glutamicum CGMCC 18932 to be irritant to the skin or eyes, or a dermal sensitiser due to the lack of data. The FEEDAP Panel concluded that the l-valine produced by fermentation using C. glutamicum CGMCC 18932 is an efficacious source of the essential amino acid l-valine for non-ruminant nutrition. To be as efficacious in ruminants as in non-ruminants, supplemental l-valine requires protection against ruminal degradation. The FEEDAP Panel expressed concerns on the use of amino acids in water for drinking for hygienic reasons.
