Description

Technical Field

[0001] The present invention relates to the technical field of essence, and particularly relates to a narcissus essence and a preparation method thereof. Background Art

[0002] Daffodils are deeply loved by people for their unique and charming fragrance. The aroma components of natural daffodils are complex and diverse, including various volatile compounds such as alcohols, esters, aldehydes, ketones, etc. At present, although the narcissus essence products on the market can simulate the aroma of daffodils to a certain extent, there is still a large gap compared with the aroma of natural daffodils, and it is often impossible to accurately restore its delicate fragrance rhyme. On the one hand, the existing narcissus essence formulas are not perfect, and some key aroma components are missing or the proportions are inappropriate. For example, the extraction or addition of some ester components with a unique sweet and fresh aroma in the daffodil aroma is insufficient, resulting in a thin overall aroma of the essence and a lack of layering. On the other hand, there are defects in the preparation process, and traditional extraction and blending methods are difficult to effectively retain and integrate the original characteristics of various aroma components. For example, during the extraction process, high-temperature treatment may cause some heat-sensitive aroma components to decompose, thus affecting the aroma quality of the essence. In addition, the existing narcissus essence performs poorly in terms of fragrance retention persistence and is difficult to meet the needs of consumers for enjoying the daffodil aroma for a long time. Therefore, it has important market value and practical significance to develop a narcissus essence that can highly restore the natural daffodil fragrance rhyme, has long-lasting fragrance retention and a reasonable preparation process. Summary of the Invention

[0003] The purpose of the present invention is to provide a narcissus essence and a preparation method thereof. This essence can highly restore the aroma characteristics of natural daffodils, has rich layering and good fragrance retention persistence.

The various components in the modifier cooperate with each other, which can make the overall aroma in the essence more harmonious. The aromas of thymol and menthol can echo with other spices in the essence, making the transition between the top note, middle note, and base note more natural and smooth, creating a harmonious aroma atmosphere. The addition of menthol, on the one hand, can activate the cold receptors of the skin, bringing a strong freshness to the essence and creating a more refreshing olfactory experience for the user; on the other hand, menthol can be skillfully combined with the terpene components originally contained in the essence to form a complementary aroma spectrum, further enriching the overall performance of the aroma.

[0018] The present invention scientifically formulates a variety of raw materials. From the fresh top note, to the rich middle note with multiple layers, and then to the long-lasting and stable base note, each fragrance note accurately simulates the aroma characteristics of narcissus, giving the essence a high aroma fidelity. At the same time, in order to improve the lasting power of the fragrance of the essence, high-efficiency fixatives such as vanillin and ambrein are added, and combined with the slow-release effect of dipropylene glycol, the retention time of the fragrance of the essence is effectively extended, effectively meeting the consumer's demand for long-lasting fragrance.

[0019] The method steps of the present invention are clear and straightforward, the operation process is simple and easy to implement, and it does not rely on complex and high-end equipment. This not only reduces the production cost, but also is very suitable for large-scale industrial production, providing strong technical support for the wide application and popularization of narcissus essence.
