Problems solved by technology

[0006] Generally speaking, the current main determination method for the detection of plasticizers is the method of gas chromatography-mass spectrometry, but due to the different properties of different plasticizers, there is no relatively unified and general method, and therefore, for When testing and measuring different types of plasticizers, it is necessary to redesign the detection method in a targeted manner

Embodiment 1

[0054] In order to determine the accuracy of the detection method provided by the application and to determine the detection limit, in the present embodiment, the applicant prepared 5 gradient standard working solution concentrations with the types of different types of benzoate plasticizers, for these The concentration of the standard working solution was automatically detected and analyzed by gas chromatography-mass spectrometry; when detecting and analyzing, the specific reference settings of the instrument parameters are as follows:

[0055] Gas chromatography conditions:

[0056] Adopt HP-5MS type 60m×0.25mm×0.25μm quartz fused capillary column;

[0057] Injection volume 1μL; carrier gas: He; flow rate: 1mL / min;

[0058] The inlet temperature is 280°C;

[0059] Programmed heating conditions: 100°C, keep for 2 minutes, rise to 200°C at 20°C / min, then rise to 280°C at a rate of 5°C / min, hold for 10 minutes, and run at 300°C for 5 minutes;

[0060] Mass Spectrometry Condi...

Embodiment 2

[0083] Since the extraction of the plasticizer in the tobacco flavor and fragrance sample has an important impact on the subsequent experimental detection, this embodiment briefly introduces the partial orthogonal experimental treatment of the relevant sample pretreatment as follows.

[0084] (1) About the choice of extraction solvent

[0085] Take the flavor and fragrance used in the cigarette processing process as the test sample, take 1.0g of the sample as the test sample, and add 5mL of deionized water to dissolve it;

[0086] Three kinds of different polar solvents such as n-hexane, ethyl acetate and dichloromethane were used as extraction agents respectively, 5 mL of extraction agents were added, and ultrasonic extraction was used for 10 minutes for extraction operation.

[0087] After the extraction was completed, the plasticizer content in the extraction solution was measured. The measurement results showed that when n-hexane was used as the extractant, the plasticizer...

Embodiment 3

[0098] Based on the optimization of related operations in Example 2, specific tests are carried out in this example, and the relevant experimental process is briefly introduced as follows.

[0099] (1) Pretreatment of tobacco flavor and fragrance samples

[0100] Weigh the flavor and fragrance sample for tobacco, add deionized water to dissolve, and mix evenly;

[0101] The flavor and fragrance for tobacco is a liquid flavor and fragrance of a certain brand used in the cigarette processing process; sampling 1.0g is used as a test sample and placed in a stoppered glass centrifuge tube;

[0102] In terms of specific dosage, the flavor and fragrance sample for tobacco: deionized water = 1.0g: 5mL.

[0103] (2) Extraction and separation

[0104] The n-hexane solution of phenylethyl acetate is used as the extractant to extract the mixed solution in step (1). After the extraction, the benzoate plasticizer is extracted into the upper layer n-hexane extraction solution, and the deio...

Abstract

The invention belongs to the technical field of detection of related substances in flavors and fragrances for tobacco, and in particular relates to a method for detecting non-ortho-phenyl ester plasticizers in flavors and fragrances for tobacco, specifically benzoate plasticizers. The method mainly includes: pretreatment of tobacco flavor and fragrance samples→extraction and separation→drying and filtration→gas chromatography-mass spectrometry automatic detection and analysis and other steps. In this application, the relevant extraction time, extraction conditions and detection method are optimized, and the target compound in the detection results has a good peak shape and a good separation degree through the targeted selection of a weak polarity capillary chromatographic column. Generally speaking, the relevant operation steps of the detection method provided by this application are easy to unify and standardize, and it has technical advantages such as short time-consuming, simultaneous detection of multiple substances at one time, good repeatability, and high sensitivity. The detection and control of relevant plasticizer content in tobacco flavors and fragrances has very important application significance.

Description

technical field [0001] The invention belongs to the technical field of detection of related substances in flavors and fragrances for tobacco, and in particular relates to a method for detecting non-ortho-phenyl ester plasticizers in flavors and fragrances for tobacco, specifically benzoate plasticizers. Background technique [0002] Tobacco flavor is a common and necessary auxiliary material in the tobacco industry, and an important additive for flavoring and flavoring tobacco products. The raw materials used to configure tobacco flavors are called tobacco flavors. These substances can be used in blends or alone. Their main functions are to enhance the aroma of tobacco products and improve the taste of smoke. [0003] Generally speaking, the concept of tobacco flavor refers to two or more tobacco flavors, which are composed of two or more tobacco flavors in a certain proportion and added with appropriate auxiliary materials, and are specially used for flavoring and flavoring...
