Description

Technical Field

[0001] The invention relates to the technical field of perfume preparation, in particular to a perfume composition with a perfume rose tea fragrance, a preparation method and an application thereof. Background Art

[0002] The scented rose belongs to a group under the rose group of the genus Rosa in the Rosaceae family. It likes plenty of sunlight and is relatively cold-resistant. It is distributed in evergreen broad-leaved forests and semi-humid evergreen broad-leaved forests at an altitude of 1600-2500m. The modern rose fragrance is divided into two major systems: rose fragrance and tea fragrance. The most well-known one is the rose fragrance, which mainly comes from the rose belonging to the genus Rosa in the Rosaceae family. Rose-scented essential oils, hydrosols, and flower cakes are also widely circulated in the market. Studies have reported that the main fragrance components of rose essential oil are citronellol, geraniol, phenylethyl alcohol, linalool, rose oxide, etc. In contrast, the circulation and research of tea-scented essential oils are relatively lacking, and the development of its essential oils has not been reported so far.

[0003] However, the scent of tea roses is strong, providing tea-scented characteristics for the evolution of modern roses. Tea-scented roses can also be called sweet fragrance, which is a type of rose fragrance. It is mild and moderate in fragrance, with green and violet tea notes as the base, which reminds people of black tea. It is a refreshing and gentle fragrance. Therefore, the tea rose group is a potential material for promoting excellent plant resources, conducting flower fragrance research and flower fragrance breeding.

[0004] However, due to industrial development, human influence and other factors, the natural habitat of tea roses has been destroyed, wild resources are decreasing, and the number of natural populations and individuals within populations are relatively small. In addition, the oil yield of rose plants is low, and one ton of roses can only produce one kilogram of oil. As a plant endemic to Yunnan, tea roses have low flower yields and it is difficult to extract essential oils for industrial development.

[0005] Therefore, it is necessary to further study a new product that is close to the natural fragrance of tea roses. Summary of the invention

[0006] One of the purposes of the present invention is to provide a fragrance composition close to the natural fragrance of tea roses and its application.

[0007] In order to achieve this object, the technical solution of the present invention is as follows:

[0008] A fragrance composition comprises eugenol, linalool, 2-hexanal and methyl salicylate, or further comprises one or more of methyl eugenol, β-ionone, β-caryophyllene, 2-phenylethanol and hexenyl acetate.

[0009] The present invention has been found that when simulating a fragrance composition that is close to the natural fragrance of tea roses, the characteristic aroma substances of tea-flavored roses known in the art, namely 3,5-dimethoxytoluene and 1,3,5-trimethoxybenzene, are not used. Only by combining and compounding specific components, a composition with a high similarity to the natural fragrance of tea roses can be obtained.

[0010] The invention uses novel chemical substances to replicate the aroma of tea, and the obtained fragrance composition has the unique aroma of Chinese roses - tea aroma, which provides a new idea for the market to develop new tea-flavor fragrance compositions with the unique floral fragrance of oriental roses.

[0011] The fragrance composition of the present invention comprises: 36-70 parts of eugenol, 2-8 parts of linalool, 3-11 parts of 2-hexanal, 2-3 parts of methyl salicylate, 0-16 parts of methyl eugenol, 0-4 parts of β-ionone, 0-6 parts of β-caryophyllene, 0-55 parts of 2-phenylethanol and 0-6 parts of hexenyl acetate.

[0012] Preferably, the fragrance composition of the present invention comprises: 70 parts of eugenol, 16 parts of methyl eugenol, 3 parts of linalool, 4 parts of β-ionone, 3 parts of 2-hexanal, 2 parts of β-caryophyllene and 2 parts of methyl salicylate.

[0013] Preferably, the fragrance composition of the present invention comprises: 36 parts of eugenol, 2 parts of linalool, 1 part of β-ionone, 3 parts of 2-hexanal, 3 parts of methyl salicylate and 55 parts of 2-phenylethanol.

[0014] Preferably, the fragrance composition of the present invention comprises: 60 parts of eugenol, 3 parts of methyl eugenol, 8 parts of linalool, 11 parts of 2-hexanal, 6 parts of β-caryophyllene, 3 parts of methyl salicylate, 3 parts of 2-phenylethanol and 6 parts of hexenyl acetate.

[0015] The fragrance composition of the present invention further comprises a solvent. Preferably, the solvent accounts for 99% by weight of the fragrance composition.

[0016] Preferably, the solvent is ethanol.

[0017] The present invention also provides a method for preparing the fragrance composition, which comprises the step of mixing the components.

[0018] The present invention further provides an application of the above-mentioned flavor composition or method in the preparation of food or daily chemical products.

[0019] Preferably, the daily chemical product is a cosmetic such as skin care products and perfumes, or a cleaning product such as a detergent, a softener or a disinfectant, or a fragrance such as an aromatherapy essential oil, granules, or beads.

[0020] The present invention further provides a product, which comprises the above-mentioned fragrance composition, and the product is food, cosmetics, fragrance or cleaning product.

[0021] The beneficial effects of the present invention are at least:

[0022] The spice composition of the present invention is the first development of a Chinese rose-specific fragrance, and uses non-tea-scented rose characteristic fragrance substances to prepare a tea-scented fragrance composition, which not only has a large olfactory recognition, but is also closer to the characteristic fragrance of natural tea roses, has simple ingredients, is easy to obtain monomers, and has low production costs. Formula simulation is used instead of essential oil extraction, which can expand the production of tea-scented essential oils, increase the market value of tea-scented essential oils, and solve the development and utilization problems caused by the low extraction rate of tea rose essential oils. Physiologically, according to the characteristics of its active ingredient substances, it can also be known that it has a certain antioxidant activity.

[0023] The fragrance composition of the present invention replicates the tea fragrance / sweet fragrance characteristics of perfume roses and enriches the types of fragrances. It has the unique tea fragrance of oriental roses and has a wide range of uses. It is expected to bring unique and natural tea-scented products to the market and meet consumers' demand for diversified fragrance experiences. DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention will be described in detail below in conjunction with examples.
