Problems solved by technology

[0004] However, the existing microcapsule flavors are generally microcapsule flavors in the state of emulsion or suspension. Emulsions or suspensions are generally unstable and easy to separate, and powdery microcapsules need to be prepared by spray drying and other methods. essence
Therefore not conducive to the perfuming of transparent media
[0005] In addition, the content of existing microcapsule flavors is very low, usually no more than 5%, so there are technical problems such as weak aroma intensity and poor aroma application effect during its use.

Abstract

The invention discloses a transparent microcapsule tuberose essence and a preparation method thereof. The transparent microcapsule tuberose essence comprises the following components by weight percent: 5-25% of tuberose essence, 5-50% of hydroxypropyl-beta-cyclodextrin, 5-40% of emulsifier and de-ionized water in balancing amount. The preparation method comprises the steps as follows: firstly, uniformly dispersing the hydroxypropyl-beta-cyclodextrin in the de-ionized water to form a hydroxypropyl-beta-cyclodextrin water solution; secondly, dropwise adding the tuberose essence into the obtained hydroxypropyl-beta-cyclodextrin water solution, and continuing to stir for uniformly dispersing the tuberose essence to obtain an emulsion; and thirdly, adding the emulsifier into the obtained emulsion, and continuing to stir uniformly to obtain the transparent microcapsule tuberose essence. The transparent microcapsule tuberose essence prepared by the preparation method has the characteristics of stable and lasting fragrance, high fragrance intensity, high essence content and the like.

Description

technical field [0001] The invention relates to a novel tuberose slow-release essence, in particular to a transparent microcapsule tuberose essence and a preparation method thereof. Background technique [0002] Tuberose, also known as evening scent or moonlight fragrance, belongs to the fragrance of flowers with a subtle and elegant fragrance. , bitter orange blossom, acacia, grass orchid mixed flavor, its unique feature is that it has herbal aroma, tuberose belongs to the heavy fragrance type, it can not only assist the floral fragrance of other floral fragrance types, but also enhance the body fragrance and fragrance of the essence Persistence, it is widely used in the deployment of daily essence, and is widely used in various daily chemical products. Because most of the ingredients in the essence are volatile organic compounds, they are easy to volatilize in the process of direct use, and some heat-sensitive and photosensitive fragrance raw materials are unstable, resu...
