preparation example Construction

[0021] The embodiment of the present invention provides a kind of preparation method of rosemary pure dew, comprises the following steps:

[0022] S01. Provide rosemary leaves, place them in steam distillation equipment for steam distillation, extract to obtain an oil-water blend, and obtain rosemary essential oil and rosemary crude hydrosol after oil-water separation;

[0023] S02. Add the crude rosemary pure dew into molecular distillation equipment, adjust the distillation temperature of the molecular distillation equipment to 10-50°C, the condensation temperature to 0-5°C, and the pressure to 1000-3000Pa, and carry out molecular distillation separation Purify to obtain light components and heavy components, and collect the heavy components to obtain rosemary hydrosol.

[0024] Specifically, in the above step S01, the choice of raw material rosemary leaves is not strictly limited, and fresh rosemary leaves or dried rosemary leaves sold in the market or picked in the wild ca...

Embodiment 1

[0058] A preparation method of rosemary crude hydrosol, comprising the following steps: take 500g dried or fresh rosemary leaves, pulverize or cut into small pieces, add distilled water to submerge the material, soak at room temperature for 12 hours, and heat on a steam distillation device Until steam flows out, distill for 3 hours, collect condensed liquid, the upper layer is rosemary essential oil, obtains 10g, and the lower layer is rosemary pure dew, obtains 100g.

Abstract

The invention provides a preparation method and application of rosemary hydrosol. The preparation method of the rosemary hydrosol comprises the following steps: providing rosemary leaves, putting into water vapor distillation equipment for water vapor distillation, extracting to obtain an oil and water co-mixture and obtaining rosemary essence and rosemary crude hydrosol after oil and water separation; adding the rosemary crude hydrosol into molecule distillation equipment, regulating the distillation temperature of the molecule distillation equipment to be 10-50 DEG C, the condensing temperature to be 0-5 DEG C and the pressure intensity to be 1000-3000 Pa, performing molecule distillation, separation and purification, obtaining light components and heavy components and collecting the heavy components to obtain the rosemary hydrosol.

Description

technical field [0001] The invention belongs to the technical field of preparation of rosemary pure dew, and in particular relates to a preparation method and application of rosemary pure dew. Background technique [0002] Pure dew, also known as water essential oil (Hydrolat), refers to a 100% saturated distillation stock solution that is separated from essential oils during the distillation and extraction process. It is a by-product of essential oils. The ingredients are natural and pure, and the fragrance is light and pleasant people. In the process of distillation and extraction, the oil and water are separated. Due to the difference in density, the essential oil will float on the upper layer, and the water will settle on the lower layer. This water is called pure dew. In addition to a small amount of essential oils, the pure dew also contains water-soluble substances in plants. It is easily absorbed by the skin due to its low concentration. In addition, the pure dew ...
