Abstract

The invention relates to a method for detecting concentration of nine compound coloring agents in auxiliary materials for reconstituted tobacco. The method comprises the following steps: preparing a mixture mother liquor of nine compound coloring agents, namely, lemon yellow, amaranth, indigo blue, carmine, sunset yellow, allura red, brilliant blue, acid red and erythrosine, and a sample solution; preparing a standard operation solution; and adopting a liquid chromatogram-series triple quadrupole spectrum analyzer for analyzing and detecting the concentration of the nine compound coloring agents in the sample solution. The method provided by the invention is accurate and reliable, is high in sensitivity and is very suitable for the analysis for the nine compound coloring agents in the auxiliary materials for the complex matrix reconstituted tobacco.

Description

technical field [0001] The invention belongs to the technical field of analysis and determination of chemical components of auxiliary materials for reconstituted tobacco leaves, such as coating liquid, tobacco leaf extract, tobacco stem extract, flavors and fragrances used in the production process of reconstituted tobacco leaves, and specifically relates to a method using liquid chromatography-tandem mass spectrometry Method for determining the concentration of nine synthetic colorants in excipients for reconstituted tobacco leaves. Background technique [0002] With the improvement of people's awareness of cigarette safety, the content of synthetic colorants in cigarettes has also received more and more attention. Strengthening the control of the content of synthetic colorants in cigarette products and raw materials has become the consensus of tobacco companies and most consumers. Tobacco accessories (such as accessories for reconstituted tobacco leaves) are one of the im...
