Embodiment 1

[0025] (1) Sample processing

[0026] Take packaging material 1 (Huanghelou cigarette packaging box provided by Wuhan Hongzhicai Packaging and Printing Co., Ltd.), cut a sample with an area of ​​10.0cm×5.5cm according to the package crease, and roll the sample with the printing side inward In the form of a cylinder, immediately put it into a 20mL headspace bottle and seal it. Place in a forced air incubator at 40°C for 14 h to allow the volatile components in the headspace vials to reach equilibrium. A 75 μm CAR / PDMS extraction tip (Supleco, USA) was inserted into the balanced sample headspace vial, the adsorption temperature was 80 °C, and the adsorption time was 40 min.

Abstract

The invention belongs to the technical field of packaging materials, and particularly relates to a method for analyzing peculiar smell components in a packaging material. A headspace solid-phase microextraction-gas chromatography-mass spectrometry-olfactory distinguishing device combined technology is adopted, and a recombination test and an abatement test are combined, so a set of analysis and detection method for the peculiar smell components in the packaging material is established. The method comprises the following steps: carrying out qualitative analysis on volatile components in the packaging material by using a gas chromatograph-mass spectrometer-olfactory discriminator combined instrument, and determining odor components causing olfactory stimulation in the packaging material; and determining the key peculiar smell components of the packaging material and the contribution of the packaging material to peculiar smell through recombination tests and abatement tests. The method can be used for detecting volatile substances and determining peculiar smell substances in the volatile substances, is beneficial to directionally reducing the content of peculiar smell components in the packaging material, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to an analysis method for odor components in packaging materials. Background technique [0002] The control of solvent residues in packaging materials is highly valued by domestic printing and packaging companies, and industry standards and enterprise standards have been issued successively to measure and limit solvent residues in packaging materials, such as common paper packaging materials for cigarettes and food. The determination of VOCs in packaging materials is mainly through solid-phase microextraction-gas chromatography, purge-and-trap-gas chromatography, headspace-gas chromatography, and headspace solid-phase microextraction-gas chromatography. Major solvent residues in inks used in the finished product or during processing. GC-MS technology, referred to as gas chromatography-mass spectrometry, is a fast, accurate, and highly sensitive qualitative a...
