Abstract

The invention relates to a microencapsulated daily use essence. The material of the capsule wall of the microencapsulated daily use essence comprises a lipid bilayer. The microencapsulated essence has the characteristics of slow volatility, good stability, good biocompatibility, safety and low price.

Description

technical field [0001] The invention relates to a microcapsule daily essence and a preparation method thereof, more specifically the invention relates to a nanoliposome microcapsule daily essence and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the pursuit of material culture, people's demand for fragrances is becoming more and more obvious, and the requirements for fragrances are also getting higher and higher. The functions of flavors can be mainly attributed to: auxiliary effect, aroma effect, stabilization effect, flavor correction effect, modification effect and substitution effect. [0003] The aroma of pure essence is often affected by various external factors due to the limitation of the nature of its components, which will eventually affect the quality of the product; therefore, using appropriate wall materials to properly wrap the essence can not only ensure the fragrance The aroma is basically s...
