Extraction process of rose essential oil
Rosa rugosa Thunb., a deciduous shrub belonging to the Rosaceae family, has beautiful flowers, colors, fragrances, and shapes, and has extremely high economic value. Known as the 'Golden Flower'. Rose essential oil is the crown of fresh flower oils, with an elegant, soft, delicate, sweet fragrance like honey, and a fragrant and overflowing rose aroma. The fragrance is very strong. Two drops can make 1 L of superior perfume, which is expensive and has the reputation of "liquid gold". Rose essential oil is mostly used in food, wine making, tea smoking, and the preparation of high-grade essence. The extraction methods of rose oil mainly include steam distillation, extraction method, and supercritical extraction method.

Steps/Methods
First step - fermentation
Soak roses in 15% salt permanently, which not only prevents them from rotting and spoiling, but also allows the oil in the flowers to spread out.
Next is the second step - distillation
Soak 30kg of Yunrose in saltwater and 60kg of saltwater in a distillation flask for atmospheric distillation. The kettle temperature is controlled between 105 ° C and 106 ° C; The temperature of the condensed distillate is 28-36 degrees Celsius. Distillation can be stopped when the distillate has no aroma or when the condensed liquid is dropped onto a glass plate and no oil droplets appear.
Step 3- Oil Water Separation
After the distillate flows through the oil-water separator, the insoluble part of the rose floats in the upper part of the separator. After one day and night, it is taken out with a mesh key and collected in a ground glass bottle; Leave it for centralized refinement.
Step 4- Adsorption
The distillate flowing out of the separator is adsorbed by three series connected adsorption columns containing activated carbon. After the activated carbon absorbs the essential oil and becomes saturated, remove the first column and collect the activated carbon in a sealed glass container for further extraction. Then move the adsorption column forward and place the column containing fresh activated carbon in the Dilan position.
Step 5- Extraction
Extract activated carbon using organic solvents. Soak for 4-6 hours for the first time, and then soak for 2 hours each time, for a total of 12 times. After oil immersion extraction in activated carbon, the organic solvents in it can be evaporated and reused.
Step 6- Rough Steaming
The immersion wave is distilled using a flammable solvent distillation method, and the water bath temperature is kept below 60 degrees Celsius.
Vacuum azeotropic distillation

Add non permanent ethanol and perform vacuum azeotropic distillation on the crude distillation residue. The vacuum degree is 99.3kPa; Water bath temperature ≤ 60 degrees. After distillation, the product is refined to become rose essential oil.
