Method for determining key odor substances in shoes

Abstract

The invention discloses a method for determining key odor substances in shoes. The method comprises the following steps of S1, collecting odor substances of the whole shoe by adopting a bag method; S2, performing subjective smell evaluation on the gas collected in the step S1, and giving a subjective evaluation result about the smell grade and type of the whole shoe; S3, respectively carrying outqualitative and quantitative detection on the gas collected in the step S1 by using HPLC and TDS / GC-MS, and determining to obtain objective key odor substances according to an odor activity method; S4, simultaneously carrying out GC-O olfactory discrimination analysis in the TDS / GC-MS detection process, and determining to obtain subjective key odor substances; and S5, determining the key odor substances of the whole shoe according to the results obtained in the steps S3 to S4. The method is advantaged in that a GC-O technology is combined with an odor activity method, the detection process issimple, cost is saved, subjective and objective evaluation results are adopted at the same time, sample consistency of finished shoe smell evaluation and sampling analysis results is ensured, the detection results are more comprehensive and important, and improvement of the environmental protection quality of shoe products can be protected.

Description

technical field [0001] The invention relates to the technical field of shoe odor detection, and more particularly, to a method for determining key odor substances in shoes. Background technique [0002] With the development of science and technology and society, people's requirements for footwear products are not only limited to their original practicability, aesthetics and durability, but also require them to be safe, comfortable and environmentally friendly. The odor emitted by finished shoes will cause extreme olfactory discomfort to consumers, which will not only directly dispel their desire to buy, but may also cause dizziness, nausea and other physical discomfort due to inhalation of odorous and harmful substances, causing complaints or disputes. [0003] It can be seen that establishing an appropriate method to test and analyze the key odor substances emitted from shoes will not only help ensure the ecological quality of finished shoes from the source, but also reduce...

Problems solved by technology

As another example, the patent 201811593232.7 describes a qualitative and quantitative analysis method for a single active substance, which combines GC-O technology and bag method for subjective evaluation of human body, and is suitable for qualitative and quantitative analysis of the odor concentration and odor intensity of a single substance, but Not suitable for simultaneous detection and analysis of multiple odor substances

[0004] Although there have been studies and reports on odor substances in shoes, the above reports only involve the detection of some odorous substances, and do not involve the analysis and determination of key odor substances in shoes. Therefore, the traceability of key odor substances in finished shoes research to be resolved
