Embodiment Construction

[0015] a. Preparation of extract: methanol, 10% ammonia water and water are prepared into a mixed solution in a volume ratio of 1:1:8 as the extract;

[0016] b. Extraction of colorants in cigarette packaging materials: crush the samples of cigarette packaging materials into 1cm 2 For left and right debris, after mixing evenly, accurately weigh 0.5±0.1mg and place it in a 25mL conical flask, then accurately add 10mL of the above extract, shake and extract for 30 minutes and then let it stand;

[0017] c. After standing for 5 minutes, pipette 2-3ml of the supernatant to pass through a 0.45μm organic phase filter, and analyze the filtrate by liquid chromatography.

[0018] Chromatographic analysis conditions: the chromatographic column adopts Agilent Zorbax SB-C 18 (250 mm×4.6mm, 5μm); detector: UV; column temperature: 30°C; detection wavelength: variable wavelength method, the wavelength of each analyte is shown in Table 3; flow rate: 1.0mL / min; injection volume: 10 μL; Qual...

Abstract

The invention discloses a method for determining colorant in cigarette package materials. The method is as below: preparing methanol, ammonia and water in the volume ratio of 1:1:8 into an extract liquor, crushing the cigarette packaging material sample, mixing well, adding the extract liquor, shaking, extracting, standing, then removing a supernatant, passing the supernatant through an organic phase membrane for liquid phase chromatographic analysis, detecting contents of six colorants including lemon yellow, Allura red, basic orange, cherry red pigment, auramine O and curcumin, conducting qualitative test by retention time combined with compound ultraviolet spectroscopy, and conducting quantification teest by using an external standard method. The invention can simultaneously detect six colorants including lemon yellow, Allura red, basic orange, cherry red pigment, auramine O and curcumin in the cigarette packaging material, can ensure the colorant content in a controllable range, accurately measure the content of various colorants in cigarette packaging material. The method has the advanategs of simple and convenient method, simple treatment, good reproducibility, high recovery rate, high sensitivity of analysis determination, accurate quantification and fast analysis, and is applicable to the analysis and determination of bulk samples.

Description

technical field [0001] The present invention relates to the determination method of the coloring agent in the packaging material for cigarettes, in particular to the determination method of six coloring agents in the packaging material for cigarettes, tartrazine, allura red, basic orange, cherry red, basic yellow O and curcumin test methods. Background technique [0002] There are clear regulations on the addition and use of colorants in China. GB 9685-2008 "Hygienic Standards for the Use of Additives for Food Containers and Packaging Materials" stipulates the types and limits of additives that are allowed to be used, among which tartrazine, allura red, alkaline None of the 6 substances including orange, cherry red, basic yellow O, and curcumin are in the list of allowed additions; the list of 151 easily abused food additives published by the Ministry of Health in 2011 includes tartrazine, allura red, and basic yellow , among which GB 2760-2011 "Standards for the Use of Foo...
