Abstract

The invention belongs to the field of spice preparation, and particularly relates to a preparation method of a rose essence embedded spice and a method for controllably releasing rose essence by carbon dioxide. The method comprises the steps: 1) mixing rose essential oil, N-alkyl imidazole and water to prepare a mixed solution; and 2) mixing the mixed solution with carbon dioxide to form an aggregate solution system. According to the rose essence embedding spice and the preparation method thereof, N-alkyl imidazole reacts with carbon dioxide in a water system to generate N-alkyl imidazole bicarbonate with surface activity, and the N-alkyl imidazole bicarbonate can embed rose essence in an aggregate form and form a stable aggregate solution system, so that the rose essence embedded spice which is stable in a normal state is constructed. By utilizing the sensitivity of the N-alkyl imidazole bicarbonate to CO2 in a water system, the N-alkyl imidazole bicarbonate can be reversely convertedinto the N-alkyl imidazole, and the N-alkyl imidazole has no surface activity, so that the controlled release of an embedding system is realized.

Description

technical field

[0001] The invention belongs to the field of perfume preparation, and in particular relates to a method for preparing rose essence-embedded fragrance and a method for carbon dioxide controllable release of rose essence. Background technique

[0002] Rose essential oil is a precious natural fragrance, mainly used in food, health products and daily chemical fields. However, rose essential oil is insoluble in water, and also has characteristics such as strong volatility and light and heat sensitivity, which cause rose essential oil to be easily lost and destroyed under storage and application conditions, which greatly limits its application.

[0003] At present, rose essential oil is often treated with embedding technology to enhance the solubility and stability of rose essential oil in water. Xu Shitao and others used saccharified glass as the wall material, and obtained rose essential oil microcapsules after homogenization, freezing, drying, and crushing (the...
