Problems solved by technology

[0010] At present, the conventional preservation of aromatic plant essential oils generally only adopts the container storage method. Since the storage of essential oils in this way has defects such as aroma volatilization, easy oxidation, and easy flammability, it needs to be improved urgently.

Embodiment 1

[0026] Mix 3 kg of gelatin, 0.4 kg of Span-80, 6 kg of lavender essential oil, and 90 kg of water at a temperature of 30°C, stir at a speed of 10,000 r / min, and obtain an emulsion;

[0027] The emulsion is spray-dried to obtain the aromatic plant essential oil microcapsules of the present invention, with a particle size of 15 μm;

[0028] The process conditions of spray drying are as follows: using CS-16 traditional Chinese medicine spray dryer, the inlet air temperature is 145°C, the outlet air temperature is 75°C, the jacket temperature is 43°C, the purge temperature is 32°C, and the air supply temperature is 42°C.

[0029] The particle size distribution of the microcapsules measured by the Mastersizer-2000 laser particle size distribution analyzer of Malvern Instruments Ltd. in the UK is about 0.2-50 μm, and the volume average particle size is D[4,3]=15.4 μm.

[0030] The results showed that the particle size distribution of microcapsules was relatively uniform, and the dis...

Embodiment 2

[0034] Mix 2 kilograms of methylcellulose, 3 kilograms of gum arabic, 5 kilograms of vanilla oil, and 90 kilograms of water at room temperature, and stir at a speed of 10000 r / min to obtain an emulsion;

[0035] The emulsion is spray-dried to obtain the aromatic plant essential oil microcapsules of the present invention, with a particle size of 17 μm.

Abstract

The invention opened a process to produce the micro-capsule of aromatic plant essential oil. The micro-capsule is made up of aromatic plant essential oil and capsule material. The particle size is 10-30um; the process is: first to dissolve the capsule material, then to dissolve the surface activator in the water phase or the oil phase, next to stir to get the latex emulsion, last to get the product by the spray drier. The product can be used to food, medicine, cosmetic, printing and dyeing and coatings.

Description

technical field [0001] The invention relates to a method for preparing microcapsules of aromatic plant essential oils. Background technique [0002] Aromatic plant essential oils are obtained through appropriate extraction methods from the flowers, pistils or whole plants of aromatic plants. Aromatic plant essential oils generally refer to plant fragrances in natural fragrances. Common plant fragrances include peppermint oil, jasmine oil, rose oil, osmanthus oil, lavender oil, divine herb oil, sweet oregano, etc. There are more than 30 kinds, and there are many different types. composed of organic compounds. [0003] Aromatic plant essential oils contain many organic compounds, are volatile, and have extremely unstable chemical properties. During use and storage, they are easy to volatilize, lose their aroma, or oxidize, decompose, and deteriorate. Therefore, the preservation and use of aromatic plant essential oils are the focus of research and development of aromatic pla...
