2022年2月24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）研究小组就依兰精油（ylang ylang oil）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。由于其在饲料中的作用与在食品中的作用基本相同，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 EFSA 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 essential oil from the flowers of Cananga odorata (Lam.) Hook.f. & Thomson (ylang ylang oil), when used as a sensory additive in feed and water for drinking for all animal species. The FEEDAP Panel concluded that the essential oil under assessment is safe up to the maximum proposed use levels in complete feed of 1 mg/kg for chickens for fattening, 1.5 mg/kg for laying hens, turkeys for fattening and rabbits, 2 mg/kg for piglets, 2.5 mg/kg for pigs for fattening, 3 mg/kg for sows, 4.5 mg/kg for cattle for fattening, sheep, goats and horses, 5 mg/kg for veal calves (milk replacer), fish, dogs and ornamental fish. For cats, the calculated safe concentration in complete feed is 1 mg/kg feed. The FEEDAP Panel considered that the use in water for drinking is safe provided that the total daily intake of the additive does not exceed the daily amount that is considered safe when consumed via feed. No concerns for consumer safety were identified following the use of the additive up to the maximum proposed use level in feed. The essential oil under assessment should be considered as irritant to skin and eyes, and as a skin and respiratory sensitiser. The use of the additive in animal feed under the proposed conditions of use was not expected to pose a risk for the environment. Ylang ylang oil is recognised to flavour food. Since its function in feed would be essentially the same as that in food, no further demonstration of efficacy is considered necessary.
