Problems solved by technology

However, this invention uses supercritical fluid extraction, the production cost is relatively high, and it is not suitable for mass production
[0004] At present, the extraction process of rose essential oil in production is backward, and the utilization rate is low, which leads to high production cost and low output of rose essential oil. At the same time, the purity of rose essential oil is not high, the application range is limited, and because of the small quantity, the sales price is expensive, and it is difficult to meet the normal market. need
[0005] Therefore, it is necessary to invent a kind of extracting method of rose essential oil for the above problems to overcome the shortcomings such as backward extraction process of rose essential oil, high production cost and low output.

Abstract

The invention relates to a rose essential oil extraction method, which comprises: 1, washing fresh rose petals, sterilizing, and drying; drying to obtain dried rose petals; step 2, putting the rose petals into refrigeration equipment, and freezing the rose petals into solid rose petals; step 3, grinding and crushing to obtain solid rose petal residues; step 4, adding distilled water; a rose petal slag mixture is obtained; step five, adding the rose petal slag mixture into a distillation pot, adding a compound enzyme, adding an activating agent, and performing enzymolysis to obtain mixed primary pulp; step 6, transferring the mixed raw stock into a distillation tank, and heating steam for distillation; collecting steam liquid from the upper end of the distillation retort through a condenser, wherein the obtained steam liquid is an oil-water mixture; and 7, putting the oil-water mixture into an oil-water separator, and separating to remove a water phase to obtain the essential oil. The preparation method is combined with a modern advanced process, the preparation method is simple, the processing cost is low, and the prepared rose essential oil is high in purity, sufficient in fragrance and capable of keeping rose fragrance for a long time.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to a method for extracting rose essential oil. Background technique [0002] Rose essential oil is the king of flower essential oils, which is extracted from rose flowers. Rose essential oil is expensive and has the reputation of "liquid gold". It is the world's most valuable high-grade concentrated essence, a boutique in essential oils, and an important and expensive raw material for manufacturing high-grade and precious perfumes. It is not only used to make cosmetics, skin care, hair care and other cosmetics, but also widely used in medicine and food. After the natural aroma of rose essential oil enters the brain through the olfactory nerve, it can stimulate the anterior lobe of the brain to secrete two hormones, endorphin and enkephalin, so that the spirit is in the most comfortable state, which is the best way to protect the soul; rose essential oil It can also reduce...
