Problems solved by technology

However, when using PY-GC-MS technology for detection, according to different detection objects and different detection purposes, a large number of pyrolysis time, temperature, heating rate, carrier gas flow rate, split ratio, ionization temperature, mass spectrometry conditions, etc. It is extremely difficult to determine the detection parameters. Therefore, so far, there have been no research and patent literature reports on the detection of volatile components in fragrances based on PY-GC-MS

Abstract

The invention provides a method for detecting volatile components in a fragrant substance based on PY-GC-MS. The method concretely comprises the following steps: 1, preparing a sample; 2, determining the conditions of detection of the volatile components through PY-GC-MS; and 3, carrying out data analysis, and carrying out qualitative and quantitative analysis. The method selects the PY-GC-MS technology to detect the content of the volatile components in the fragrant substance in order to solve a problem that the volatile components in the fragrant substance in practical production and life is difficult to qualitatively and quantitatively detect; and the method can be used for detecting the volatile components in various forms of fragrant substances, like fragrant blocks, fragrant powder, vanilla fragments, sesame oil and perfume, has the characteristics of simple operation, low detection limit, good experiment reappearance, visual and reliable experiment data, is especially suitable for the detection of a tiny amount of a sample, can realize the comparison of the composition and the content of the volatile components between / among different samples, has a wide applicability, and provides a rapid detection idea and method for the development, production and safety monitoring of the fragrant substance.

Description

technical field [0001] The invention relates to a method for rapidly detecting the composition and content of volatile components in fragrances based on rapid pyrolysis-gas chromatography-mass spectrometry (PY-GC-MS method). Background technique [0002] Fragrance has a long history. Since the direct burning of spice plants in ancient times, people have been working hard to improve the method of using spices. On the one hand, the value of spices can be fully utilized, and on the other hand, it is more convenient for people to use spices. The current fragrances can be divided into: burning incense, smearing incense, fragrant soup, wearing incense, etc. according to the way people use fragrances to emit fragrance; with perfume etc. According to the shape of incense, it can be divided into petal incense, end incense, thread incense, lying incense, incense tower, incense pill, coil incense and so on. [0003] The smell of incense mainly comes from the volatile components in t...
