2021年11月8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）研究小组就柠檬提取物（lemon extract）作为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，专家小组得出结论，在1000 mg/kg全价饲料和250 mg/kg饮用水的最大建议使用水平下，该添加剂对所有动物物种都是安全的。由于它在饲料中的功能与在食物中的功能基本相同，因此认为没有必要进一步证明其功效。部分原文报道如下：

Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of an aqueous extract of Citrus limon (L.) Osbeck (lemon extract) when used as a sensory additive in feed for all animal species. The FEEDAP Panel concluded that the additive under assessment is safe for all animal species up to the maximum proposed use levels of 1,000 mg/kg complete feed and 250 mg/kg water for drinking. No concerns for consumers were identified following the use of lemon extract up to the highest safe level in feed. The additive should be considered a skin and eye irritant, and a potential corrosive. The use of the extract in animal feed under the proposed conditions was not expected to pose a risk for the environment. Lemon extract was recognised to flavour food. Since its function in feed would be essentially the same as that in food, no further demonstration of efficacy was considered necessary.
