Problems solved by technology

Usually, these tasks mainly rely on the experience of the perfumer and the analysis of simple physical and chemical indicators. The allowable range of uncertain factors and physical and chemical indicators (relative density, refractive index, alcohol value, ester value, etc.) is relatively large, resulting in poor repeatability and controllability of flavoring results

Embodiment 1

[0056] Firstly, GC / MS analysis was carried out on 344 commonly used fragrance materials, including 158 natural fragrance materials and 186 synthetic monomer fragrance materials. For each fragrance raw material, a database of characteristic mass spectra of fragrance raw materials is established according to the method described in the invention. Part of the database data see figure 1 and Table 1.

[0060]

[0061] Then carry out the characteristic mass spectrum search, and carry out the NIST spectral library search (using third-party software such as chemstation software, etc.) The MS spectrum is used to search the characteristic mass spectrum peaks of natural fragrance raw materials to identify the natural fragrance raw materials contained in the essence. By identifying the characteristic mass spectrum peaks of natural fragrance raw materials, the presence or absence...

Abstract

The invention discloses a digital fragrance identification method based on a characteristic mass spectrum. The method mainly includes the extraction of the characteristic mass spectrum of the essence and the analysis of the components of the essence. The extraction of the characteristic mass spectrum is to analyze the peaks of the GC / MS spectrum of the essence, and Extract the characteristic mass spectrum to construct the characteristic mass spectrum library; component analysis refers to searching the characteristic mass spectrum library for the GC / MS spectrum of the fragrance to identify the components of the fragrance raw materials contained in the fragrance; this method realizes the efficient identification of fragrance ingredients and formulas, and can effectively replace the auxiliary Artificial traditional experience olfactory identification method, scientific method, high accuracy, wide application range.

Description

technical field [0001] The invention relates to a method for identifying ingredients of flavors and fragrances, in particular to a digital method for distinguishing fragrances based on characteristic mass spectra, belonging to the field of flavors and fragrances. Background technique [0002] With the improvement of people's living standards, flavors play an increasingly important role in daily necessities, food, and cigarettes, which play an important role in improving product quality and flavor. Tobacco flavor, as an important part of cigarette production, plays an important role in improving the taste of cigarettes and highlighting the flavor of tobacco. [0003] The development of fragrance includes fragrance identification, imitation fragrance, fragrance creation and so on. Fragrance identification refers to the identification of the composition and differences of flavor components, which is often done in the development of flavors. Flavors and fragrances have complex...
