The fragrance precursor substance used in the present invention is not particularly limited as long as it is decomposed by heat to generate a fragrance component, and known glycosides, glycerides, peptide derivatives, amino acid derivatives and phosphorus of fragrances. Acid ester derivatives and the like can be used. These fragrance precursor substances can be synthesized by organic synthesis, enzymatic synthesis, or a combination thereof. In the present invention,
One of these fragrance precursor substances may be blended, or a plurality of them may be blended and blended.

The above-mentioned fragrances are generally sandalwood, agarwood, benzoin, etc., but geraniol, citronellol,
Citronellal, citral, eugenol, phenethyl alcohol, thymol, isoeugenol, nerol, lavandulol, phenoxyethyl alcohol,
Linalool, green leaf alcohol, L-menthol, borneol, benzyl alcohol, vanillin and the like can also be used.

The blending amount of the fragrance precursor substance varies depending on the kind of the fragrance used, but is 0.0 with respect to the combustion fragrance.
The amount may be 1 to 20% by weight, more preferably 0.05 to 10% by weight, further preferably 0.1 to 5% by weight.

Such a combustion fragrance product can be obtained by adding a fragrance precursor substance to a raw material of a usual combustion fragrance product, and kneading and molding the mixture. It can also be obtained by dissolving a fragrance precursor substance in water or the like and impregnating it with a combustion fragrance material.

Examples of the burning fragrance material of the present invention include burning incense, incense, incense, mosquito coiling incense, and the like.

[0010]

According to the present invention, these fragrance precursor substances are
Maintains a good scent even after long-term storage, as compared to conventional combustion fragrances that release scent during storage because heat is decomposed and scent is released only when heat is applied. can do.

The present invention will be specifically described below with reference to examples. Reference Example 1 (Synthesis of phenethyl galactoside) Phenethyl alcohol (special grade reagent manufactured by Wako Pure Chemical Industries, Ltd.) 4.0
g and 20 g of lactose in 4 mM potassium phosphate buffer (p
H7.0) dissolved in 500 ml. To this, 10000 units of Sumilacto GLL (manufactured by Shin Nippon Chemical Co., Ltd.) was added and reacted at 40 ° C. for 20 hours, and then at 100 ° C.
The reaction was stopped by treating for a minute to obtain a reaction product. Unreacted raw materials in the obtained reaction product were extracted and removed with chloroform to obtain an aqueous layer fraction, and this aqueous layer fraction was applied to a 50 ml DIAION HP-20 (manufactured by Mitsubishi Chemical Corporation) column. The solution was passed to adsorb phenethylgalactoside. After washing this column with 1 liter of distilled water, 5
The phenethyl galactoside was eluted with 00 ml of methanol. The obtained phenethyl galactoside fraction was concentrated under reduced pressure, and the residue was pulverized in an ethanol-hexane system to obtain 1.51 g of phenethyl galactoside.

After thoroughly kneading 50 g of CMC, 30 g of brown pigment, and 650 g of water with a kneader, the kneaded product is freeze-dried,
Three types of incense were prepared by arranging irregular particles obtained by crushing with a crusher into several millimeters with a comb. The thus-prepared three kinds of incense were mixed in a): b): c) in a weight ratio of 3: 3: 4. At this time, 100 g of the mixture
On the other hand, phenethylgalactoside 2 synthesized in Reference Example 1
g was added. The burned incense produced in this way is determined by igniting whether or not the scent of phenethyl alcohol is gradually released, based on the following criteria.
Sensory evaluation was carried out by 5 women. Further, in order to investigate whether or not a good scent is gradually released even after storage for a long period of time, the above-mentioned burnt scent was left at room temperature for 2 months, and then the same sensory evaluation was performed.

For comparison, a burning incense was prepared in the same manner as above except that 1 g of phenethyl alcohol was used instead of phenethyl galactoside. The burned aroma thus produced was subjected to a sensory evaluation on whether or not the scent of phenethyl alcohol was gradually released by ignition, after the production and after being left for 2 months, according to the following evaluation criteria. Table 1 shows the results. The values in the table are the average values of the evaluations of 10 panelists.

[Table 1]

As is clear from Table 1, the incense stick of the present invention (Example 1) gradually released the scent after ignition. In addition, a good scent was released even after standing at room temperature for 2 months. On the other hand, in the conventional type of incense added in the form of perfume without adding in the form of glycoside (Comparative Example 1), sustained release of fragrance was not observed, and in the case of being left at room temperature for 2 months. The scent was low.

Example 2, Comparative Example 2 (incense stick) 140 g of coal ash and 60 g of activated alumina were mixed, and 20 g of CMC, 2 g of phenethylgalactoside synthesized in Reference Example 1 and an appropriate amount of water were added to this powder to form a paste.
This was sufficiently dried with hot air, pulverized into granules of 10 to 30 mesh, and then a brown dye was uniformly sprayed to obtain a colored fragrance material. This fragrance material was extruded in a linear shape with a hydraulic cylinder, cut into a predetermined length, and then dried with hot air until the water content became 5% or less to produce a linear incense stick.
For comparison, a filamentous incense stick was prepared in the same manner as above except that 1 g of phenethyl alcohol was used instead of phenethyl galactoside. The incense thus prepared was subjected to ignition to release the scent of phenethyl alcohol gradually, and whether or not a good scent was released even after being left at room temperature for 2 months, as in Example 1. The sensory evaluation was carried out based on the evaluation criteria. Table 2 shows the results.

[0018]

[Table 2]

As is clear from Table 2, the incense stick of the present invention (Example 2) gradually released the scent after ignition. In addition, the incense after leaving it to stand at room temperature for 2 months also released a good scent. On the other hand, the conventional type incense (comparative example 2), which was added in the form of perfume without being added in the form of glycoside, did not show the sustained release of the fragrance, and after being left at room temperature for 2 months, The scent was low.
