2024年10月23日，据欧盟食品安全局（EFSA）消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就油茶籽提取物（Camellia oleifera C.Abel seed extract）作为除有鳍鱼类外所有动物饲料添加剂的安全性和有效性发表科学意见。
经过评估，专家小组认为在建议的使用条件下该添加剂对消费者和环境是安全的。当根据建议的使用条件使用时，该添加剂具有作为乳化剂的潜力。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 a Camellia oleifera C.Abel seed extract (Cosap®) as technological feed additive for all animal species except fin fish. In the absence of adequate tolerance studies in the target species or toxicological studies with the additive under assessment, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) could not conclude on the safety of C. oleifera extract for the target species. The use of the additive in animal nutrition is not expected to cause concern for consumer safety. The additive is considered as irritant to the eyes and mucous membranes. No conclusions can be reached on the potential of the additive to be irritant to the skin or to be a dermal sensitiser. The use of the additive under the proposed conditions of use is considered safe for the terrestrial compartment. However, no conclusion can be reached on the safety of the additive for the environment when used in feed of aquatic animals other than fin fish. The Panel concluded that the additive has the potential to be efficacious as an emulsifier when used according to proposed conditions of use.
