摘  要:
富硒肉是通过在饲料中添加硒强化剂的方法提升动物产品中硒含量。目前,针对动物组织中硒的研究主要集中在硒源和不同外源硒水平对动物组织中硒含量、分布的影响上。通过高效液相色谱-电感耦合等离子体质谱、体积排阻-电感耦合等离子体质谱等色谱联用方法研究富硒肉中含硒化合物的种类、含量、分布规律,可以了解硒在生物体中的代谢途径和转化机制。

摘  要:
In recent years,with the continuous improvement of people s living standards,more and more kinds of Se-rich food products are emerging,such as Se-rich meat,of which in the production,animal feed is fortified with Se enhancer in an effort to elevate Se content in meat.Although most recent studies of Se in animal tissues focus on Se sources and the effect of exogeous Se levels on the content and distribution of selenium in animal tissues,the kind,contents and distribution of Se-containing compounds in Se-rich meat have been investigated by high performance liquid chromatography(HPLC),inductively coupled plasma mass spectrometry(ICP-MS),size-exclusion chromatography(SEC)-ICP-MS,etc,which can provide some understanding of the metabolic pathway and transformation mechanism of Se in living organisms.
