Embodiment 1

[0027] A method for extracting magnolia pure dew, the method is: pick fresh magnolia flowers, clean the material, spin-dry the water on the surface of the magnolia flowers, then evenly spread them in an air-conditioned room with a temperature of 20℃~24℃, and Spray the alcohol mixture in the air-conditioned room, the humidity in the room reaches 90% or more, let it stand for 1 to 2 hours, and then take it out. When taking it out, the raw material will contact the air to promote the volatilization of alcohol and ethyl acetate attached to the surface of the raw material, and use steam Distillation is carried out, and the pure dew vapor obtained from the distillation is condensed, and the condensed solution is the magnolia dew.

[0028] When the weight of the magnolia hydrosol and the weight of the dried magnolia flower are 1.2:1, the distillation is stopped.

[0029] The alcohol mixture is: 10% alcohol, 5% ethyl acetate and the remainder is pure water; the preparation method is: disso...

Embodiment 2

[0036] A method for extracting magnolia pure dew, the method is: pick fresh magnolia flowers, clean the material, spin-dry the water on the surface of the magnolia flowers, then evenly spread them in an air-conditioned room with a temperature of 20℃~24℃, and Spray the alcohol mixture in the air-conditioned room, the humidity in the room reaches 90% or more, let it stand for 1 to 2 hours, and then take it out. When taking it out, the raw material will contact the air to promote the volatilization of alcohol and ethyl acetate attached to the surface of the raw material, and use steam Distillation is carried out, and the pure dew vapor obtained from the distillation is condensed, and the condensed solution is the magnolia dew.

[0037] When the weight of the magnolia hydrosol and the weight of the dried magnolia flower are 1.4:1, the distillation is stopped.

[0038] The alcohol mixture is: 10% alcohol, 5% ethyl acetate and the remainder is pure water; the preparation method is: disso...

Embodiment 3

[0045] A method for extracting magnolia pure dew, the method is: pick fresh magnolia flowers, clean the material, spin-dry the water on the surface of the magnolia flowers, then evenly spread them in an air-conditioned room with a temperature of 20℃~24℃, and Spray the alcohol mixture in the air-conditioned room, the humidity in the room reaches 90% or more, let it stand for 1 to 2 hours, and then take it out. When taking it out, the raw material will contact the air to promote the volatilization of alcohol and ethyl acetate attached to the surface of the raw material, and use steam Distillation is carried out, and the pure dew vapor obtained from the distillation is condensed, and the condensed solution is the magnolia dew.

[0046] Distillation is stopped when the weight of the magnolia hydrosol and the weight of the dried magnolia flower are 1.5:1.

[0047] The alcohol mixture is: 10% alcohol, 5% ethyl acetate and the remainder is pure water; the preparation method is: dissolve e...

Abstract

The invention relates to the technical field of hydrolate extraction, in particular to a method for extraction of magnolia denudata hydrolate. The method is characterized by including: picking fresh magnolia denudate, performing cleaning, spin-drying the moisture on the magnolia denudate surface, then evenly spreading the magnolia denudate in an air-conditioned room at a temperature of 20DEG C-24DEG C, also spraying an alcohol mixed solution in the air-conditioned room to make the humidity in the room reach 90% or above, conducting standing for 1-2h, then taking the magnolia denudate out and performing distillation with steam, subjecting the hydrolate steam obtained by distillation to condensation to obtain a solution, i.e. the magnolia denudata hydrolate. The method provided by the invention effectively improves the extraction amount of magnolia denudata hydrolate, and can enable the magnolia denudata hydrolate to maintain the characteristics of magnolia denudata maximumly.

Description

Technical field [0001] The invention relates to the technical field of extracting pure dew, in particular to a method for extracting magnolia pure dew. Background technique [0002] Hydrosol, also known as water essential oil ( Hydrolate ) Refers to a 100% saturated distilled liquid separated from essential oils during the distillation and extraction process of essential oils. It is a by-product of essential oils. The ingredients are natural and pure, and the fragrance is light and pleasant. [0003] In the prior art, some technical solutions are also disclosed on how to extract the pure dew. [0004] Relevant Chinese patent documents were retrieved as follows: [0005] 1. Chinese patent <application number> 201710037023.3 <Name of Invention> Centella asiatica pure dew and its preparation method and application <Summary> Disclosed is a Centella asiatica pure dew and its preparation method and application. Pick fresh Centella asiatica, wash, remove impurities, cut it...
