Embodiment 1

[0019] A kind of method of solid-phase microextraction analysis ginger flower fragrance composition:

[0020] 1. Wash the fresh ginger flower with clean water and drain at room temperature;

[0021] 2. The solid-phase microextraction device was aged at the gas chromatograph inlet for 30 minutes;

[0022] 3. Put the fresh ginger flowers in the headspace bottle and incubate for 10 minutes in a water bath at 45°C, then insert the solid-phase microextraction device into the headspace bottle, and slowly and carefully unscrew the extraction fiber head for 30 minutes of aroma extraction . After the extraction time is over, slowly and carefully withdraw the extraction head and take out the extractor;

[0023] 4. Quickly transfer the solid-phase microextraction device to the gas chromatography-mass spectrometry inlet, and use the Agilent GC-MSD system (Agilent Technologies GC-6890 gas chromatograph & 5973N-MS mass spectrometer) for gas chromatography-mass spectrometry analysis . Eq...

Embodiment 2

[0031] An analysis of the aroma components of ginger flower essential oil:

[0032] 1. Wash the fresh ginger flower with clean water, drain the water at room temperature, and use steam distillation to obtain ginger flower essential oil;

[0033] 2. Ginger flower essential oil is dewatered and filtered, and then 0.1 μL of essential oil is taken for gas chromatography-mass spectrometry analysis by direct sampling. Gas chromatography-mass spectrometry was performed with an Agilent GC-MSD system (Agilent Technologies GC-6890 gas chromatograph & 5973N-MS mass spectrometer). Equipped with DB-5MS (5% phenylmethylsiloxane, 60mm×0.25mm, 0.25μm) capillary column, the carrier gas is 99.99% nitrogen, the flow rate is 1.0mL / min, and the split ratio is 30:1. The column temperature was first raised from 50°C to 120°C at a rate of 10°C / min (hold for 5 min), then increased to 160°C at a rate of 3°C / min (hold for 10 min), and finally increased at a rate of 2°C / min to 230°C (hold for 10min). ...

Embodiment 3

[0040] Method for determining aroma splitting based on sensory evaluation experiments:

[0041] 1. Convene a sensory evaluation team consisting of 10 men and 10 women, aged between 20 and 40 years old. All team members have received more than 2 weeks of sensory evaluation training;

[0042] 2. Members of the sensory evaluation team are first required to be familiar with the aromas represented by aromas such as floral, green, fruity, spicy, woody, and cool, and then familiarize themselves with the aroma intensity standards;

[0043] 3. Based on the data obtained by gas chromatography-mass spectrometry, the sensory evaluation team determined the aroma pathways of fresh ginger flower and ginger flower essential oil, and gave a comprehensive score. The results are shown in Table 3.

[0044] Table 3 Aroma splitting and scoring

[0045] Aroma branch floral green fragrance Spicy fruity cool feeling fresh ginger flower 4.12 2.54 1.02 0.5 1.24 Ginger ...

Abstract

The invention discloses hedychium coronarium essence. The formula of the hedychium coronarium essence comprises the following components in percentage by mass: 20-60% of a flower fragrance component, 8-20% of a green fragrance component, 0-15% of a fruit fragrance component, 2-10% of an animal fragrance component, 1-5% of a herbal medicine-cool feeling component, 0.05-10% of a spicy fragrance component and the balance of a solvent. According to the method, aroma branches and characteristic aroma components are determined by evaluating the aroma of fresh hedychium coronarium and hedychium coronarium essential oil; therefore, the aroma composition of the hedychium coronarium essence is determined. The hedychium coronarium essence disclosed by the invention is natural in components, pleasant and appropriate in fragrance, and has a good application prospect.
