Problems solved by technology

[0011] In the existing test technology, there are few research reports on the analysis of prohibited compounds (methanol, sec-butanol, safrole, imidazole, coumarin, xylene musk and sesamol) in flavors and fragrances by gas chromatography-mass spectrometry, limited to the chemical analysis of the above substances. The properties are different, and there is no detection method that can simultaneously detect seven prohibited compounds at one time.

Embodiment Construction

[0034] In order to achieve the purpose of the present invention, the present invention is achieved through the following technical solutions: a method for simultaneously detecting seven prohibited compounds in flavors and fragrances, wherein the seven prohibited compounds are methanol, sec-butanol, safrole, imidazole, coumarin Primer, xylene musk and sesamol, the method may further comprise the steps:

[0035] Step 1, prepare the extract containing internal standard: take naphthalene as the internal standard, weigh 400 mg of naphthalene, accurate to 0.1 mg, and measure with CH 2 Cl 2 As a solvent, set the volume in a 100ml brown volumetric flask to obtain a 4mg / ml internal standard mother solution, then take 1ml of the internal standard mother solution, and use CH 2 Cl 2 As a solvent, set the volume in a 1000ml brown volumetric flask to obtain an extract containing an internal standard with a concentration of 4μg / ml.

[0036]Step 2, prepare standard working solution: Weigh ...

Abstract

The invention discloses a method for detecting seven prohibited compounds in flavors and fragrances. The seven prohibited compounds are methanol, sec-butyl alcohol, safrole, imidazole, coumarin, musk xylene and sesamol. The detection method can accurately and rapidly detect the contents of the seven prohibited compounds in flavors and fragrances, is suitable for quality safety control of fragrance raw liquid and auxiliary solvents in the industries such as food, daily-use chemical industry, tobacco and pharmacy, and the has the characteristics of simple operation, rapidness, accuracy, good repeatability, high sensitivity and the like.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical inspection, analysis and testing of flavors and fragrances, and mainly relates to a simultaneous determination method for the contents of methanol, sec-butanol, safrole, imidazole, coumarin, xylene musk and sesamol in flavors and fragrances. Background technique [0002] In the process of cigarette product formula design and manufacturing, based on improving product sensory comfort and processing technology requirements, it is often necessary to add functional additives such as moisturization, flavor enhancement, sweetness, and combustion support, and food-grade alcohol as an auxiliary solvent. As an important component of cigarettes, flavors and fragrances have always attracted the attention of the tobacco industry and cigarette consumers for their quality and safety. [0003] Methanol is a volatile liquid with an alcohol-like odor. It can damage human cells and tissues through ski...
