Problems solved by technology

At present, the method for the determination of the aroma-causing substances in the flavor of the popcorn is mainly based on instrumental detection, but the contribution of the instrumental detection to the aroma compounds cannot be identified
For example, patent CN201611029810.5 discloses a screening method for volatile organic compounds in cigarette filter popping beads. This method uses headspace sampling combined with comprehensive two-dimensional gas chromatography-mass spectrometry to scan and analyze the samples, and obtains 31 Volatile organic compounds, but it is impossible to determine the effective aroma components and the degree of aroma contribution in the aroma components
There are many kinds of volatile aroma components contained in the essence, and only a few of them have been identified so far. There are few reports on the analysis of the aroma components of the essence in the popcorn, and there are few detections of the aroma components in the popcorn. The total amount of flavor in the popping beads is small, which cannot meet the needs of the machine, and the addition of other solvents will affect the volatility of the flavor components in the popping beads

Embodiment 1

[0034] An analysis method for volatile fragrance components, comprising the following steps:

[0035] S1. Sample pretreatment: puncture the popping beads, the liquid in the popping beads flows out and is adsorbed on the smelling stick, put the smelling stick and the shell of the popping beads into the purge and trap tube for purging and trapping, The purge and trap conditions are as follows: the purge time is 2min, the desorption temperature is 250°C, and the desorption time is 2min; the purge temperature is room temperature without heating, the purge gas is high-purity nitrogen, and the transfer line temperature is 230°C ;

[0036] S2. Use GC-MS to separate and characterize the pre-treated samples: perform GC-MS detection and analysis on the samples processed in step S1. The GC-MS analysis conditions are: the chromatographic column is a capillary column, and the chromatographic column specification is 30m ×250μm×0.25μm, the inlet temperature is 230°C, the split ratio is 10:1...

Embodiment 2

[0043] An analysis method for volatile aroma components, the steps of which are basically the same as those in Example 1, the difference being that the object of study is the 2# popping balls in the commercially available double ice popping balls cigarette filter

Embodiment 3

[0045] An analysis method for volatile aroma components, the steps of which are basically the same as those in Example 1, the difference being that Example 1 and Example 2 studied the finished popcorn, and what is studied here is the popcorn that has not been made into popcorn essence.

Abstract

The invention discloses a volatile fragrant component detection and analysis method and application. The method comprises the following steps: sample pretreatment: carrying out purging and trapping onsamples; carrying out separation and qualitative analysis on the samples, obtained after pretreatment, through GC-MS; and carrying out identification and confirmation on the samples, obtained after pretreatment, through GC-O. The method not only can effectively avoid interference of a high boiling point solvent, but also can obtain sensory information of components which have important contribution to aroma; the detection method is simple to operate and requires few samples; detection cycle is within 16min, and match degree of each component is higher than 80%; and the method is a fast and accurate analysis method for detecting and analyzing the aroma components in cigarette filter capsule, and meanwhile, provides good technical guidance and data support for preparation of essence of thecigarette filter capsule.

Description

technical field [0001] The invention relates to the technical field of volatile substance analysis, and more specifically, to a detection and analysis method for volatile aroma components and its application. Background technique [0002] Volatile aroma substances, as a kind of aroma-enhancing and regulating substances, are used in many fields. For example, adding popping beads to cigarette filter rods to impart aroma to cigarettes can achieve artificially controllable release of characteristic aromas during smoking. The aroma components in the popping beads do not participate in the combustion, and directly achieve the flavor enhancement of cigarettes through volatilization, which has the effect of enriching the taste level. In recent years, it has been used as an effective means of flavor enhancement, and has been favored by more and more cigarette brands. develop rapidly. At present, the method for the determination of the aroma-causing substances in the flavor of the po...
