Embodiment 1

[0039] Step 1: Accurately weigh 100.0g of rose essential oil raw material (methyl eugenol content 2.35%), add it to the molecular still, set the temperature at 50°C, preheat at 30°C, condense at 3°C, wiper speed at 300rpm, and distill The speed is 1g / min, and the evaporation pressure is 0.03MPa, until the rose essential oil is completely collected by the heavy component collection tank and the light component collection tank.

[0040] Step 2: Add the heavy component obtained in Step 1 as a raw material into the molecular still, set the distillation temperature to 85°C, the preheating temperature to 30°C, the condensation temperature to 3°C, the rotational speed to 300rpm, the distillation speed to 1g / min, and the evaporation pressure to 0.01MPa. Until the raw material is completely collected by the heavy component collection tank and the light component collection tank.

[0041] Step 3: Merge the light components in step 1 and the heavy components in step 2. After testing, the...

Embodiment 2

[0044]Step 1: Accurately weigh 100.0g of rose essential oil raw material (methyl eugenol content 2.35%), add it to the molecular still, set the temperature at 60°C, preheat at 30°C, condense at 3°C, wiper speed at 100rpm, and distill The speed is 3g / min, and the evaporation pressure is 0.02MPa, until the rose essential oil is completely collected by the heavy component collection tank and the light component collection tank.

[0045] Step 2: Add the heavy component obtained in Step 1 as a raw material into the molecular still, set the distillation temperature to 80°C, the preheating temperature to 30°C, the condensation temperature to 3°C, the rotational speed to 100rpm, the distillation speed to 1g / min, and the evaporation pressure to 0.01MPa. Until the raw material is completely collected by the heavy component collection tank and the light component collection tank.

[0046] Step 3: Merge the light components in step 1 and the heavy components in step 2. After testing, the ...

Embodiment 3

[0048] Step 1: Accurately weigh 100.0g of rose essential oil raw material (methyl eugenol content 2.35%), add it to the molecular still, set the distillation temperature to 70°C, the preheating temperature to 30°C, the condensation temperature to 3°C, and the film scraping speed to 400rpm, The distillation speed is 5g / min, and the evaporation pressure is 0.01MPa, until the rose essential oil is completely collected by the heavy component collection tank and the light component collection tank.

[0049] Step 2: Add the heavy component obtained in Step 1 as a raw material into the molecular still, set the distillation temperature to 90°C, the preheating temperature to 30°C, the condensation temperature to 3°C, the rotational speed to 400rpm, the distillation speed to 3g / min, and the evaporation pressure to 0.02MPa. Until the raw material is completely collected by the heavy component collection tank and the light component collection tank.

Abstract

The invention discloses a method for reducing the content of methyl eugenol in rose essential oil, comprising: step 1, carrying out molecular distillation on rose essential oil, the distillation temperature is 50-70°C, the evaporation pressure is 0.01-0.03 MPa, and light components and Heavy component; step 2, carry out molecular distillation on the heavy component obtained in step 1, the distillation temperature is 80-90°C, the evaporation pressure is 0.01-0.03MPa, and collect light component and heavy component; step 3: combine the light component obtained in step 1 Components and the heavy components obtained in step 2 are obtained rose essential oil with reduced methyl eugenol content. By adopting the method of the invention, the content of methyl eugenol in the rose essential oil prepared by the prior art can be further reduced by more than 85%, and when the effect is better, the content of methyl eugenol can be removed by more than 90%. The content of methyl eugenol in the rose essential oil prepared by the invention is far lower than the existing technical level, can reduce the influence of the limit of methyl eugenol when the rose essential oil is applied, and make the dosage selection of the rose essential oil more extensive.

Description

technical field [0001] The invention relates to a method for purifying rose essential oil, in particular to a method for reducing methyl eugenol in rose essential oil. Background technique [0002] Rose essential oil is a precious essential oil extracted from rose petals. It not only has an elegant, pure, and sweet aroma, but also has the functions of regulating qi, promoting blood circulation, beautifying the skin, and astringent. It is often used as an additive for beauty, skin care, and hair care. It is used in the manufacture of cosmetics, as well as in the manufacture of food, health care products and medicines. [0003] The chemical composition of rose essential oil is diverse, including nerol, geraniol, citronellol, eugenol, methyl eugenol, heptadecane, nonadecane, hexadecane and other compounds, which have been isolated and identified in literature reports There are about more than 300 kinds of chemical compounds in human body, these ingredients endow it with unique...
