Abstract

The invention provides a preparation method of rose essential oil. The preparation method comprises a pretreatment step and a distillation step, wherein the pretreatment step comprises the following specific steps: S11, picking and cleaning: cleaning picked rose petals with clear water, and draining for later use; s12, freezing treatment: freezing the rose petals obtained in the step S11 at the temperature of -25 to -5 DEG C for 1-3 hours; and S13, defrozing with water: adding deionized water into the frozen rose petals obtained in the step S12, and slowly melting the ice at the temperature of80-100 DEG C until the rose petals are softened, wherein the adding amount of the deionized water meets the condition that the material-liquid ratio is (3-6):1. The preparation method disclosed by the invention has the advantages of higher essential oil extraction rate and higher essential oil extraction efficiency, and can be used for obtaining high-purity and non-destructive rose essential oil.The invention also provides the rose essential oil prepared by the preparation method.

Description

technical field [0001] The invention belongs to the technical field of extraction of plant active components, and in particular relates to a preparation method of rose essential oil and rose essential oil. Background technique [0002] With the development of society and the improvement of people's living standards, rose essential oil, known as "liquid gold", has been favored by more and more people. Rose essential oil has great benefits for human health. Metabolism function, and rose essential oil also has very good effect on aging skin at the same time, so rose essential oil is widely used in fields such as skin care products, medicine, has huge economic value and practical value. [0003] Rose essential oil is extracted from natural roses. The existing extraction methods of rose essential oil mainly include pressing method, steam distillation method, solvent extraction method, supercritical fluid / subcritical fluid method, molecular distillation and other methods. Among t...
