FIELD OF THE INVENTION

[0001] This invention relates to the field of fragrance and flavor. Illustratively, the invention relates to ketone compounds represented by the following general formula (1)

[0002] (wherein A is C═O or CH—OH, R1 is hydrogen atom or methyl group and R2 is methyl group or ethyl group, with the proviso that R2 is ethyl group when R1 is hydrogen atom, and R2 is methyl group when R1 is methyl group), which have marine-like and modern green-like fragrance characteristics and fatty-like and fatty green-like flavor characteristics, and to use thereof as aromatic components.

BACKGROUND OF THE INVENTION

[0003] With the recent diversification of goods such as various food materials, food additives, food and drink (including table luxuries), aromatic cosmetics, health preservation and sanitation materials, sundries and medicaments, a demand for new fragrance and flavor to be used therein has been increasing and great concern has been directed toward the development of fragrance and flavor materials having unique and highly palatable fragrance and flavor. Particularly with the recent rise in people's intention to love nature, great concern has been directed toward the development of new fragrance and flavor materials derived from natural compounds or those which are similar or analogous to natural compounds, regarding highly palatable marine-like fragrance and flavor, green-like fragrance and flavor and fatty-like fragrance and flavor by which natural environment can be characteristically imagined, and also from the safety point of view.

[0004] Great concern has been directed toward the development of fragrance and flavor materials having high palatability, particularly regarding different marine-like and modern green-like fragrance and flavor which are insufficient by the conventionally used marine-like fragrance and flavor including Calone (trade name, Pfizer) and green-like fragrance and flavor including cis-3-hexenol, and fatty-like and milk-like fragrance and flavor which are insufficient by the conventional butter-like fragrance and flavor including acetoin and diacetyl.

SUMMARY OF THE INVENTION

[0005] Accordingly, the object of the invention is to provide ketone compounds having marine-like, modern green-like and fatty green-like fragrance and flavor which satisfy these requirements, and fragrance compositions and flavor compositions containing them.

[0006] Under such circumstances, the present inventors have conducted intensive studies with the aim of achieving the object and found as a result of the efforts that high palatability fragrance compositions having modern green-like and marine-like fragrance characteristics and flavor compositions having fatty-like and milk-like flavor characteristics can be obtained by adding ketone compounds represented by the following general formula (1)

[0007] (wherein A is C═O or CH—OH, R1 is hydrogen atom or methyl group and R2 is methyl group or ethyl group, with the proviso that R2 is ethyl group when R1 is hydrogen atom, and R2 is methyl group when R1 is methyl group), and further found that these compositions have considerable fragrance and flavor keeping effects.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The following describes the invention further in detail.

[0020] The ketone compounds represented by the following general formula (1)

[0021] (wherein A is C═O or CH—OH, R1 is hydrogen atom or methyl group and R2 is methyl group or ethyl group, with the proviso that R2 is ethyl group when R1 is hydrogen atom, and R2 is methyl group when R1 is methyl group) to be used in the invention are known compounds.

[0022] Among these four compounds, three compounds 3,5-decanedione, 3-methyl-4-hydroxy-2-nonanone and 5-hydroxy-3-decanone are substances which have not been studied as fragrance or flavor with no reports on their fragrance and flavor characteristics.

[0023] Only 3-methyl-2,4-nonanedione has been reported on its fragrance and flavor characteristics, namely as a lard-like or straw-like odor regarding reversion flavor of soybean [International Patent Publication No. 506,960/1996; FOOD & FOOD INGREDIENTS JOURNAL OF JAPAN, Vol. 168, pp.. 61-76; Fett Wiss. Technol., (1989), 91(6), 225 - 30] and as an aromatic substance of green tea component (Prog. Flavor Precursor Stud. Proc. Inc. Conf., pp. 401 - 407, 1993).

[0024] However, nothing has been reported on its use in food flavors as a sea food base flavor or milk base flavor, and nothing has been reported on its use as fragrance.

[0025] The ketone compounds of the invention represented by the general formula (1) can be obtained by extracting them from natural materials or by a chemical synthesis method.

[0026] In order to obtain the ketone compounds of formula (1) of the invention in a large amount, it is desirable to use a chemical synthesis method.

[0027] Production method of the ketone compounds of formula (1) of the invention is carried out, e.g., by the reaction shown below.

[0028] Production method of 3-methyl-2,4-nonanedione of the invention is described in the following further in detail.

[0029] Production of 3-methyl-2,4-nonanedione is carried out, e.g., by the following method.

[0030] That is, hydroxyketones (2a and 2b) are obtained by carrying out carbon-carbon bond formation reaction of n-hexylaldehyde with methyl ethyl ketone in the presence of a base catalyst and then subjected to oxidation reaction to effect formation of diketones (3a and 3b).

[0031] The compound of interest can be isolated by subjecting the thus obtained ketone compounds to a general separation purification method (e.g., a column chromatography).

[0032] Illustrative examples of the thus obtained four ketone compounds are 3-methyl-4-hydroxy-2-nonanone (2a), 5-hydroxy-3-decanone (2b), 3-methyl-2,4-nonanedione (3a) and 3,5-decanedione (3b).

[0033] As will be shown in the following Examples, all of these compounds have marine-like and modern green-like fragrance characteristics and fatty-like and fatty green-like flavor characteristics, particularly, 3-methyl-4-hydroxy-2-nonanone (2a) and 3-methyl-2,4-nonanedione (3a) have highly palatable excellent marine-like and modern green-like fragrance and odor strength and also have significant fragrance keeping characteristic and stability, and a fragrance composition such as a fragrance providing agent or fragrance improving agent having high palatability can be provided by formulating them.

[0034] Also, since 3-methyl-4-hydroxy-2-nonanone (2a) and 3-methyl-2,4-nonanedione (3a) have highly palatable excellent marine-like and modern green-like fragrance characteristics and fatty-like and fatty green-like flavor characteristics, a flavor composition such as a flavor providing agent or flavor improving agent having high palatability can be provided by formulating them.

[0035] In addition, the action and effect of desired fragrance keeping and residual fragrance can be particularly increased by formulating the ketone compounds of the invention.

[0036] The term “green-like fragrance, marine-like fragrance, modern green-like fragrance, fatty-like flavor and fatty green-like flavor” as used herein means the following fragrance or flavor.

[0037] That is, the green-like fragrance is a greenish and refreshing fragrance as if fresh plants or tree leaves are squeezed or a fragrance characteristic to fresh vegetables such as cucumber and white muskmelon, and it means a fragrance which reminds a greenish feeling.

[0038] The marine-like fragrance is generally a seashore fragrance generating from the sea and the seashore and means a seaweed-like green fragrance which reminds fragrance of the tide of the sea and the coast.

[0039] The modern green-like fragrance means a fresh and young greenish fragrance which, among green-like fragrances, particularly reminds vegetables and un-ripe fruits.

[0040] The fatty-like fragrance generally means a fragrance which reminds aroma of oils and fats typified by aliphatic aldehyde compounds, feeling of animal fats such as lard and milk fat such as butter.

[0041] In addition, the fatty green-like fragrance generally means which, among green-like fragrances, particularly a greenish fragrance accompanied by a fatty feeling.

[0042] A fragrance composition and a flavor composition in which generally used fragrance components are further added to the ketone compounds of the invention can also be used as fragrance components and flavor components. Examples of the other fragrance which can be added include various types of synthetic aroma chemical, natural aroma chemical, natural essential oil, citrus fruit oil and animal aroma chemical, of which floral green base fragrance compositions are particularly desirable, and a broad range of fragrance components described, e.g., in Arctander S., “Perfume and Flavor Chemicals”, published by the author, Montclair, N.J. (U.S.A.), 1969, can be used. Their typical examples include α-pinene, limonene, cis-3-hexenol, phenylethyl alcohol, styralyl acetate, eugenol, rose oxide, linalool, benzaldehyde, muscone and Thesarone (Takasago International Corporation).

[0043] Illustratively, when the ketone compounds of the invention are formulated in, e.g., synthetic essential oils such as bergamot oil, galbanum oil, lemon oil, geranium oil, lavender oil and mandarin oil, they can improve effects of the synthetic essential oils by providing mild, full-bodied, fresh and highly palatable fragrance and flavor, as well as their persistency by increasing dispersing and retaining properties, which are originally possessed by natural essential oils. Also, they harmonize well also with citrus fruit essential oils such as of orange, lime and grapefruit and natural essential oils such as lavender oil, vetiver oil, cedar wood oil, citronella oil, geranium oil, lavandine oil and sandal wood oil and can emphasize characteristics of these essential oils, so that they render possible the preparation of novel fragrance composition and flavor composition which are mild, full-bodied and almost natural and also show persistency by increasing dispersing and retaining properties.

[0044] In addition, their formulation in flavor compositions such as of strawberry, lemon, orange, grapefruit, apple, pineapple, banana, melon, green tea, Oolong tea, salmon, sardine, small dried sardine, shrimp and crab, which are prepared from , e.g., various types of synthetic aroma chemicals, natural aroma chemicals, natural essential oil, citrus fruit oil and animal aroma chemicals, renders possible preparation of fragrance compositions and flavor compositions which provide mild, full-bodied and almost natural marine-like, modern green-like, fatty-like and fatty green-like aromas, as well as fresh and highly palatable aromas, and also show emphasized persistency by increasing dispersing and retaining properties.
