摘要:

为建立一种分析油炸食品中痕量丙烯酰胺的灵敏准确、快速简便、成本低廉的新型流动注射化学发光分析方法,样品中的丙烯酰胺经提取后,利用其对鲁米诺-过氧化氢化学发光体系的增强作用进行测定,并对测定体系的条件进行优化和讨论。结果表明:该法测定丙烯酰胺的线性范围为1.0×10-6~1.0×10-3mol/L,相关系数r=0.9993,方法检出限为3.95×10-8mol/L,加标回收率为91%~107%,样品测定的相对标准偏差(RSD)为1.3%(n=9)。该法简便快捷、成本低廉、实用性强,用于测定油炸食品中的丙烯酰胺,结果令人满意。

Abstract:

A new sensitive accurate and cost-effective method established for the determnation of trace acrylamide in
fried foods by using flow injection chemiluminescence. The proposed method was based on enhanced chemiluminescence detection
of the luminal/hydrogen peroxide system in the presence of the acrylamide extracted from samples. Instrumental
parameters and the reaction system were optimized. The linear range of this method was 1.0 × 10-6–1.0 × 10-3 mol/L with a
correlation coefficient of 0.9993, and the detection limit was 3.95 × 10-8 mol/L. The recovery rate was 91%–107%, with
RSD (n = 9) of 1.3%. Satisfactory results were obtained in its practical application.
