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。由于其在饲料中的功能与在食品中的功能基本相同，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 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 leaves, stalks and twigs of Cinnamomum cassia (L.) J. Presl (cassia leaf oil) when used as a sensory additive (flavouring) in feed and water for drinking for all animal species. Owing to the presence of styrene in cassia leaf oil, the FEEDAP Panel is not in the position to conclude for long-living animals and animals for reproduction. For ‘short-living’ animals, the FEEDAP Panel concluded that cassia leaf oil is considered as safe up to the maximum proposed use levels in complete feed of 28.5 mg/kg for chickens for fattening and other minor poultry, 38 mg/kg for turkeys for fattening, 51 mg/kg for piglets and other minor Suidae, 61 mg/kg for pigs for fattening, 100 mg/kg for veal calves (milk replacer), 60 mg/kg for cattle for fattening and other ruminants for fattening, 30 mg/kg for horses, 25 mg/kg for rabbits, 125 mg/kg for salmonids and other fin fish. For the other minor species, the additive is considered as safe at 28.5 mg/kg complete feed. For ‘short-living’ animals, the FEEDAP Panel considered the use in water for drinking as 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 consumers were identified following the use of the additive at the use levels considered safe in feed for the target species. When handling the essential oil, exposure of unprotected users to styrene cannot be excluded. Therefore, to reduce the risk, the exposure of the users should be minimised. The use of the additive under the proposed conditions in animal feed was not expected to pose a risk for the environment. Cassia leaf oil 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.
