欧盟评估山梨醇酐月桂酸酯作为所有动物饲料添加剂的环境安全性

 

　　据了解，山梨醇酐月桂酸酯添加剂由山梨糖醇（及其酸酐）与椰子油中的脂肪酸酯化而成。经过评估，专家小组得出结论，山梨醇酐月桂酸酯对陆地和水生环境的风险不大，根据既定的使用条件，预计使用评估中的添加剂对环境不存在安全隐患。部分原文报道如下：

 

　　The additive sorbitan monolaurate consists of sorbitol （and its anhydrides） esterified with fatty acids derived from coconut oil. It is currently authorised in the European unio and it is intended to be used as a technological additive （functional group of emulsifiers）， in feedingstuffs for all animal species, at a maximum concentration of 85 mg/kg complete feed. In 2019, the EFSA Panel on Additives and Products or Substances used in Animal Feed （FEEDAP ） issued an opinion on the safety and efficacy of sorbitan monolaurate. Owing the lack of data, the FEEDAP Panel could not conclude on the safety of the additive for the environment. The applicant submitted new data （fate and degradation as well as ecotoxicity data） that were evaluated in the present opinion. The absorption, distribution, metabolism and excretion of structurally related compounds （sorbitan monostearate and sorbitan trioleate） indicate that the additive is expected to be partially metabolised. In addition, sorbitan monolaurate and some related compounds are readily biodegradable. The limited available data on the effects of sorbitan monolaurate in marine crustaceans and in marine sediment indicate that the ecotoxicity of the additive is low, in consistency with the very low acute toxicity of sorbitan esters. Overall, the FEEDAP Panel concludes that a risk of sorbitan monolaurate to terrestrial and aquatic environment is unlikely. Therefore, no safety concerns for the environment are expected from the use of the additive under assessment according to the established conditions of use.
