Problems solved by technology

However, liquid chromatography has certain limitations. The complex matrix of the sample will interfere with the analysis of various mixed pigments. The UV detector only relies on the retention time for qualitative analysis, which is prone to false positive or inaccurate quantitative results.

Abstract

The invention discloses a method for detecting 11 kinds of pigments in reconstituted tobacco leaves for tobacco, which comprises the following steps: 1) establishing the high-resolution mass spectrum library information of 11 kinds of pigments by using double ternary high-performance liquid chromatography and high-resolution mass spectrometry, and the high-resolution mass spectrometry Database information includes pigment name, retention time, [M+H] + and [M‑2H] 2‑ Accurate mass number of ions and accurate mass number of characteristic fragment ions; 2) Pretreatment of reconstituted tobacco leaves for the tobacco to be tested: the reconstituted tobacco leaves for the tobacco to be tested are extracted with a solvent to obtain the liquid to be tested. The invention has the advantages of simple operation, quick detection and high sensitivity, and can be applied to daily detection of reconstituted tobacco leaves in cigarettes.

Description

technical field [0001] The invention relates to a detection method, in particular to a detection method of 11 pigments in reconstituted tobacco leaves. Background technique [0002] Pigments, also known as colorants, can be divided into two categories: natural pigments and synthetic pigments according to their sources. Natural pigments are extracted from animals and plants, have poor stability and are expensive. Artificial pigments refer to organic pigments prepared by artificial chemical synthesis methods, mainly made of aniline dyes separated from coal tar. According to structure, artificial pigments can be classified into azo, xanthracene and diphenylmethane, etc.; according to solubility, they can be divided into fat-soluble and water-soluble pigments. A large number of research reports have shown that almost all artificial pigments not only cannot provide nutrition for the human body, but also some artificial pigments will endanger human health, lead to decreased fert...
