2019年5月15日，据欧盟食品安全局（EFSA）消息，动物饲料添加剂和产品（FEEDAP）研究小组就从万寿菊中提取的叶黄素（lutein）和叶黄素/玉米黄素（lutein/zeaxanthin）作为家禽（除火鸡外）饲料添加剂的安全性和有效性发表科学意见。

 

　　据了解，此种添加剂用于小型家禽品种的产蛋和育肥。添加剂在饲料和饮用水中的使用被认为是生物等效的。

 

　　部分原文报道如下：

 

　　The Panel on Additives and Products or Substances used in Animal Feed （FEEDAP） evaluated （i） lutein from a saponified extract from Tagetes erecta obtained via extraction and saponification （lutein not less than 85% of total carotenoids （TC）） and （ii） lutein/zeaxanthin extract from Tagetes erecta obtained via extraction, saponification and isomerisation （lutein not less than 45% and zeaxanthin not less than 35% of TC）。 The maximum proposed use level of 80 mg TC from saponified Tagetes extract/kg complete feed for chickens for fattening and laying hens is safe for these animal categories. This conclusion can be extrapolated to minor poultry species for fattening and laying. The conclusions on saponified Tagetes extract for poultry for fattening and laying are extended to the saponified/isomerised Tagetes extract.
