摘　　要：为了研究浒苔和江蓠等大型海藻作为饲料添加剂的作用,利用层相色谱、液相色谱、气质联用仪检测饲喂浒苔和江蓠的仙居鸡肉的成分变化。结果表明:浒苔粉和江蓠粉使鸡肉的总蛋白、粗脂肪、肌球蛋白、甜菜碱、己醛、乙酸乙酯和2-丙烯酸甲酯的含量明显提高;浒苔粉提高了苏氨酸、缬氨酸、精氨酸含量,江蓠粉提高苏氨酸、异亮氨酸和谷氨酸含量;鸡胸肉中共检出匹配率在90%以上的45种风味物质,腿肉中共检出33种。浒苔粉对脂肪烃、醇、硫化物影响明显;江蓠粉对醛、酯、酮类物质含量均有较显著提高。早期投喂海藻粉将有利于各种物质的积累。In order to explore the role of algae in feed additives,the meat composition of Xianju chicken fed Enteromorpha sp.or Gracilaria sp.were analyzed by liquid chromatography and gas chromatography-mass spectrometry.Results indicated that both Enteromorpha sp.and Gracilaria sp.powders could obviously increase the contents of total protein,crude fat,myosin,betaine,hexanal,ethyl acetate and 2-methyl acrylate in chicken meat.The contents of essential amino acids such as threonine,valine and arginine exhibited a significant improvement in chicken fed Enteromorpha sp.powder;whereas,threonine,isoleucine and glutamic acid in Xianju chicken fed Gracilaria sp.A total of 45 and 33 flavor components were detected in breast meat and leg meat of chicken,respectively.As a conclusion,Enteromorpha sp.powder has an obvious promoting effect on the accumulation of hydrocarbons,alcohol and sulfur compounds in chicken meat,while,Gracilaria sp.powder has an obvious promoting effect on the accumulation of aldehyde,ester and acetate.Therefore,the feeding of algae powder will facilitate the accumulation of nutrients in chicken meat.
