Embodiment 1

[0029] Pick roses around 7 o'clock in the morning, crush the whole flowers, add 20% salt water 1.5 times the volume of roses, and ferment at 70°C for 30 hours. Put the fermented rose and the fermented liquid into the extraction kettle together, according to the extraction pressure of 28Mpa, extraction temperature of 60°C, separator I pressure of 10Mpa, temperature of 35°C, separator II of pressure of 6.5Mpa, temperature of 50°C, carbon dioxide flow rate of 32kg / h Extract 2.5h to get rose crude oil. Rose crude oil is molecularly distilled according to the conditions of: distillation temperature 100°C, vacuum degree 600Pa, rose crude oil flow rate 0.8ml / ml, scraping film speed 3200r / min, cooling temperature 9°C to obtain light yellow oily rose essential oil, and the yield of rose essential oil 0.12%, relative density: 0.8917, refractive index 1.4647, specific optical rotation 4°36'; acid value 2.87, ester content 61.32%.

Abstract

The invention belongs to the field of plant essential oil extraction and discloses rose essential oil and a preparation process thereof. According to the invention, the rose essential oil is prepared by carrying out fermentation, supercritical CO2 extraction and molecular distillation on rose from a rose garden in Qixian Mountain. The entire preparation process has the advantages of low temperature, high efficiency, no pollution and the like, and the maximal yield of the essential oil is up to 0.12%. The obtained rose essential has light yellow color and pure fragrance, and contains multiple fragrance-presenting components and total 61 ingredients.

Description

technical field [0001] The invention belongs to the field of essential oil extracted from plants, and relates to a rose essential oil and a preparation process thereof. Background technique [0002] Rose (Rose rugosa Thunb) is a plant of the genus Rosa in the family Rosaceae, an upright deciduous shrub with sweet fragrance in flowers, and extracting rose oil from roses is one of the oldest essential oils.
