摘要:

偶氮类非食用色素具有致癌作用,快速检测出食品中的偶氮色素至关重要。本文着重概述了偶氮色素苏丹红和酸性橙的检测方法:分光光度分析法、色谱分析法以及电化学检测方法,并对新技术在苏丹红检测方面的应用做了阐述。认为应选择快速、高效灵敏、成本低、普适性强的检测方法。电化学的溶出伏安法及循环伏安法均可对单一偶氮化合物进行快速、准确的定性及定量测定,但对多种偶氮类非食用色素共存体系准确定性有待进一步探讨。

Abstract:

Azo-compound inedible pigments are considered as one kind of carcinogens, thus it is necessary to rapidly detect them in food. This article mainly reviewed the detection of azo-compound pigments such as Sudan I and acid orange by spectrophotometric analysis, chromatography and elecrtochemistry analysis, and expatiated on the application of new technology in detection of Sudan I. It was proposed that celerity, sensitivity, low cost and strong applicability are the main selecting criteria of detection method. Both of stripping and cyclic voltammetries of electrochemistry may rapidly, accurately, qualitatively and quantitatively detect single azo-compound in food, but for coexisted azo-compounds their veracity still need to be further discussed.

Key words: synthetic pigment, azo-compound pigment, Sudan I, acid orange
