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.
