应欧洲委员会的要求，欧洲食品安全局被要求对真八角油（不含或含有植物叶片）在所有动物物种的饲料和饮用水中作为感官添加剂的安全性和功效提供科学意见。对于寿命长且有繁殖能力的动物，饲料添加剂与动物饲料添加剂及产品或物质（FEEDAP）专题小组认为，以0.6毫克/千克的剂量在饲料中使用该添加剂对于蛋用鸡和兔子来说是低风险的，对于母猪和乳牛是1.0毫克/千克，对于绵羊/山羊、马和猫是1.6毫克/千克，对于犬是1.9毫克/千克，对于观赏鱼是6.5毫克/千克。而对于寿命较短的动物，当剂量为83.3毫克/千克时，该专题小组对于小牛、绵羊/山羊、肉牛和肉马没有安全担忧；当剂量为83.8毫克/千克时，对于鲑鱼没有安全担忧；当剂量为24.8毫克/千克时，对于肉火鸡没有安全担忧；当剂量为18.5毫克/千克时，对于肉鸡没有安全担忧；当剂量为33.3毫克/千克时，对于仔猪没有安全担忧；当剂量为40毫克/千克时，对于肉猪没有安全担忧；当剂量为29.3毫克/千克时，对于肉兔没有安全担忧。这些结论可推广到其他生理相关的物种。对于任何其他物种，以0.6毫克/千克的剂量，该添加剂被认为是低风险的。预计在动物饲料中使用真八角油对消费者和环境都不会产生风险。正在评估的添加剂应被视为对皮肤和眼睛有刺激性以及皮肤和呼吸系统致敏剂。由于富含假香芹酮（≥1%），该添加剂被归类为可疑的致遗传缺陷和致癌物质，因此应采取相应的处理措施。由于真八角的果实及其制品被认为是食品的调味剂，其在饲料中的作用与此相同，因此不需要进一步证明其功效。© 2023 European Food Safety Authority. 由Wiley‐VCH GmbH代表欧洲食品安全局出版的EFSA Journal。

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of star anise oil from the fruit (without or with the presence of plant leaves) of Illicium verum Hook.f., when used as a sensory additive in feed and water for drinking for all animal species. For long-living and reproductive animals, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) considered of low concern the use of the additive in complete feed at 0.6 mg/kg for laying hens and rabbits, 1.0 mg/kg for sows and dairy cows, 1.6 mg/kg for sheep/goats, horses and cats, 1.9 mg/kg for dogs and 6.5 mg/kg for ornamental fish. For short-living animals, the Panel had no safety concern when the additive is used at 83.3 mg/kg for veal calves, 73.3 mg/kg for sheep/goats, cattle for fattening and horses for meat production, 83.8 mg/kg for salmonids, 24.8 mg/kg for turkeys for fattening, 18.5 mg/kg chickens for fattening, 33.3 mg/kg for piglets, 40 mg/kg for pigs for fattening and 29.3 mg/kg for rabbits for meat production. These conclusions were extrapolated to other physiologically related species. For any other species, the additive was considered of low concern at 0.6 mg/kg. The use of star anise oil in animal feed is expected to be of no concern for consumers and for the environment. The additive under assessment should be considered as an irritant to skin and eyes, and as a dermal and respiratory sensitiser. Due to the high concentration of estragole (≥ 1%), the additive is classified as suspected of causing genetic defects and of causing cancer and should be handled accordingly. Since the fruit of I. verum and its preparations are recognised to flavour food and their function in feed would be the same, no further demonstration of efficacy was necessary.© 2023 European Food Safety Authority.
