摘要: 富含淀粉类食品经高温烹饪会产生较高浓度的丙烯酰胺。丙烯酰胺是一种对人类可能的致癌物质。本文建立了用气相色谱-质谱直接测定食品中丙烯酰胺含量的方法。采用选择离子采集模式,方法的线性范围是0.5~15.5mg/L,线性相关系数为r=0.99943,回收率在94%以上,相对标准偏差小于5.4%,定量检测限25μg/kg。是一种快速、灵敏的测定方法。

Abstract: Starch-rich foods will produce high concentration acrylamide by high temperature cooked. Acrylamide is probably carcinogenic to humans. A method for directly determining acrylamide in foods by GC/MS is defined. Acquisition mode is selected ion monitor (SIM).The linear range of this method is0.5~15.5mg/L, linear correlation coefficient is 0.99943, recovery is more than 94%, relative standard deviations is less than 5.4%, and the limits of quantification is 25μg/kg. This is a rapid and sensitive method.
