[0076] Preparation of analysis samples can be carried out as shown in Examples described later. In addition, the ratio of the components of various molecular weights in the molecular weight distribution can also be obtained as shown in the examples described later, specifically, by calculating the total value (total peak area) of the target peak area to the obtained peak area ratio to obtain.
[0077]In the molecular weight distribution of the solid composition of the present invention, the proportion of dextrin with a molecular weight of 100,000 or more is not particularly limited, but is, for example, 2.0 to 28%, preferably 3.0 to 25%, more preferably 4.0 to 20%. In addition, in the molecular weight distribution of the solid composition of the present invention, the proportion of dextrin with a molecular weight of 150,000 or more is not particularly limited, for example, it is 1.0 to 20%, preferably 2.0 to 15%, more preferably 2.5 to 12%. . In addition, in the molecular we...

[0139] Example 1. Test using a solid composition containing linalool, geraniol and 2-methylbutyraldehyde
[0140] (1) Preparation of solid composition
[0141] (i) Preparation of solid composition stock solution
[0142] Use tea extract as solid material (trade name: GT204S, raw material: green tea (made in China)), linear dextrin A (Matsutani Chemical, TK-16, weight average molecular weight: 910, DE: 18), linear paste Refined B (Sanwa Starch Industry, Sandec#30, weight average molecular weight: 120,000, DE: 2-5) and cyclodextrin (Cyclochem, α-cyclodextrin, weight average molecular weight: 973) to prepare a solid composition . Specifically, the ratios shown in Table 1 below were used to prepare a total of 6,000 g of a solid mixture, and 14,000 g of water was added thereto to prepare a total of 20,000 g (Brix 30%) of a solid composition stock solution. In addition, the above-mentioned tea leaf extract solid raw material is what dried and solidified the tea leaf extract, and ...

[0198] Example 3. Test using a tea extract containing linalool, geraniol, and 2-methylbutyraldehyde at high concentrations (1) Preparation of solid composition
[0199] (i) Preparation of tea extract
[0200] A stock solution of a solid composition was prepared in the same manner as in (1)(i) of Example 1 above. Its composition is shown in the table below.
[0201] [Table 7]
[0202]
[0203] (ii) Preparation of distillates containing linalool, geraniol and 2-methylbutyraldehyde
[0204] In addition to the above (i), a tea extract containing linalool, geraniol, and 2-methylbutyraldehyde was prepared. Specifically, 15 kg of tea leaves of commercially available stalk tea were weighed, mixed with 100 kg of water, and kept at 50° C. for 2 hours to heat-treat the tea leaves. Then, put the treated solution into a steam distillation kettle in a state containing tea leaves, and carry out boiling steam distillation under the conditions of a steam pressure of 0.25 MPa, a steam fl...
