Problems solved by technology

[0003] However, in many cases, the sample is a powder. Due to the particularity of the powder flavor, most of the flavors have a relatively low boiling point and are easy to volatilize, and the content of raw materials in the flavor is not high, so it is difficult to collect the fragrance.

Embodiment 1

[0018] (1) Mix the powder essence sample with acetone in a mass-to-volume ratio of 1g:1ml, stir with a stirrer at medium speed for 60 minutes, stand at 0°C for 4 hours to get the upper layer solution, filter with filter paper, and then use the leaching solution for 3000 rpm Centrifuge for 10 minutes and take the supernatant;

[0019] (2) Naturally volatilize the supernatant in a fume hood. When the remaining amount is greater than 2-3 mL, stop the volatilization, take out the remaining solution, and perform GC-MS injection analysis;

[0020] (3) Repeat the extraction and analysis of steps (1) to (2) with ether, and summarize the two analysis results to obtain the sample analysis results. see the results figure 1 and figure 2 .

[0021] The chromatographic conditions used for GC-MS are as follows:

[0022] Chromatographic column: 19091J-433, HP-5;

[0023] 30m*0.25mm*0.25μm;

[0024] Carrier gas: helium, 35cm / sec, 0.9ml / min;

[0025] Column oven: 50℃, keep for 1min;

...

Embodiment 2

[0032] (1) Mix the powdered essence sample with acetone in a mass-to-volume ratio of 1g:4ml, stir with a stirrer at medium speed for 80 minutes, stand at 2°C for 4 hours to get the upper layer solution, filter with filter paper, and then use the leaching solution for 3000 rpm Centrifuge for 20 minutes and take the supernatant;

[0033] (2) Naturally volatilize the supernatant in a fume hood, and when the remainder is greater than 2 to 3 mL, stop the volatilization, take out the remaining solution, and carry out GC-MS injection analysis; the chromatographic conditions used by GC-MS are the same as those in Example 1;

[0034] (3) Repeat the extraction and analysis of steps (1) to (2) with ether, and summarize the two analysis results to obtain the sample analysis results.

Abstract

The invention relates to a method for analyzing a powder essence sample through a leaching method. The method comprises the steps that 1, the powder essence sample is mixed with acetone according to the mass-to-volume ratio of 1 g to 1-4 ml, stirring is conducted for 60-90 min, standing is conducted at the temperature ranging from 0 DEG C to 4 DEG C for 4-5 h, an upper solution is taken, filtration and centrifugation are conducted, and supernate is taken; 2, the supernate is volatilized naturally in a fuming cupboard, 2-3 ml of solution is left, the solution is taken out, and GC-MS sample injection analysis is conducted; 3, extraction and analysis in the first step and the second step are conducted repeatedly through diethyl ether, analysis results of the two times are collected, and a sample analysis result can be obtained. According to the method for analyzing the powder essence sample through the leaching method, sample pretreatment is easy to operate, the time is short, the experiment efficiency can be obviously increased, the reproducibility is good, and essence imitation is greatly facilitated.

Description

technical field [0001] The invention belongs to the field of flavor sample analysis, and particularly relates to a method for analyzing powder flavor samples by using a leaching method. Background technique [0002] Quantitative analysis is a very important link in flavor analysis, especially in the process of imitating flavors. Because in the process of fragrance mixing, when most raw materials can be quantified quickly and relatively accurately, it is of great significance for the perfumer to realize the rapid imitation of the essence. [0003] However, in many cases, the samples are powders. Due to the particularity of powder flavors, most flavors have relatively low boiling points and are easy to volatilize, and the content of raw materials in the flavors is not high, so it is difficult to collect aromas. Solids cannot be directly analyzed by GC-MS, so samples must be processed. At present, most of the domestic use is a single leaching non-concentration method to extra...
