[0027] Reference Example 1: Using SPME method to analyze the fragrance of white lotus
[0028] Select a bouquet of white lotus with a strong fragrance from the white lotus pond in Huishan, Yilaoyi, Muan County, South Jeolla Province, and use polyacrylate to form a polyacrylate coated extraction head (Polyacrylate Fiber) of 85 μm in 2 hours to absorb and collect the white lotus. Fragrance components emitted. The collection lasted two days to complete.
[0029] Seal the extraction head (Fiber) that collected the aroma components, move it to and insert it into the inlet of GC-MS, desorb for 2 minutes, and perform GC-MS analysis. The GC-MS analysis conditions are as follows.

Embodiment 1
[0057] Embodiment 1: prepare new combination spices according to main component content difference
[0058] From the above test example 2, it was determined that the main components of the unique fragrance in white lotus are pentadecane, p-xylylene dimethyl ether, heptadecane, sabinene, limonene, myrcene and α-terpineol. Therefore, the present inventors used these seven ingredients to prepare a combination fragrance that can reproduce the inherent fragrance of white lotus and has a good preference, and prepared new combination fragrances as shown in #1 to #4 in Table 5 below.
[0059] It can be seen from combinations of spices #1 to #4 that the total content of the seven spices varies within the range of 80-95% by weight (unit: weight %) while maintaining a certain proportion of the contents of these seven main components. The specific composition is shown in Table 5 below.

[0067] Example 2: Preparation of flavor-improved fragrances based on the analysis of a professional panel of judges
[0068] In order to improve the fragrance of sample #3 which is the closest to the white lotus in the above table 6 in similarity and preference, as shown in the following table 7, it is guaranteed that pentadecane, p-xylylene dimethyl ether, heptadecane, sabinene, limonene, The content of myrcene and α-terpineol was 90% by weight (consistent with sample #3 in Table 6), and the artificial substance 2-phenylethyl alcohol was added to prepare new combination fragrance samples of samples #A to #G.
[0069] At this time, according to the collective judgment of professional perfumers, 2-phenylethanol was selected as an artificial compound, and its content was set at 0.5% by weight, 1.0% by weight, 1.5% by weight, 2.0% by weight, 2.5% by weight, 3.0% by weight, and 3.5% by weight were added to the composition, and other components were added according to the content o...
