Osmanthus fragrans essential oil is a premium essential oil that is very popular for adding a unique osmanthus flavor to all kinds of foods, beverages and cosmetics.
There are two common extraction methods for
osmanthus essential oil:
1. Water vapor distillation
Water vapor distillation is a common method
for extracting essential oils from plants. The distillation equipment has a
large volume, and flowers concentrated in the flowering period can be processed
in large quantities, and the operation is simple and low-cost, which is the
main method for the extraction of essential oils from fresh flowers. This
method is suitable for the extraction of active ingredients that are volatile,
can be vaporized with water vapor without being destroyed, do not react with
water, and are difficult to dissolve in water.
Will be fresh or dry treatment of aromatic
plant raw materials into the distiller, add water to heat together, under the
action of steam, the petals of terpenes, alcohols, lipids and other essential
oils and water vapor evaporation, containing essential oils of the water vapor
through the conduit to collect the cooling of the steam will be cooled into a
liquid, and then in accordance with the difference in the density of the water
and the essential oils are separated out. Using the essential oil components
volatile, insoluble in water and do not react with water characteristics,
condensation collection, and finally get the essential oil.
The distillation process requires careful
control of temperature and time to ensure that only the pure aroma components
of osmanthus are extracted.
The resulting osmanthus essential oil has a
relatively fresh and light odor, and holds its fragrance for about 2 hours.
2. Solvent extraction method
Organic solvent extraction method is the
use of volatile organic solvents, continuous reflux extraction or cold
immersion, hot immersion extraction of plant components will be dissolved, and
then through the distillation of the extract or decompression distillation to
remove the solvent can be obtained from the crude essential oil. The solvent
extraction method is used to extract natural flavors from plant materials, and
the yield of flavors obtained by this method is significantly increased.
Generally, the solvent and plant material
into the extractor mixed extraction, so that the volatile substances dissolved
in the solvent; and then filtered; subsequently, evaporation and concentration
of the solvent to get the filtrate, the concentrate is called extract (wax, a
mixture of essential oils); the extract is dissolved in ethanol,
low-temperature filtration to remove impurities; and finally, evaporation of
ethanol to get the essential oil.
Can be extracted to a more complete
osmanthus odor, more intense, calm, with a heavier sense of wood, holding time
of about 5 hours.
The following is a detailed description of
the preparation process of osmanthus essential oil.
1. Preparation of raw materials: Prepare
high-quality osmanthus flower petals, cooking alcohol, distilled water, etc.,
wash and dry osmanthus flowers.
2. Crushing: The osmanthus petals are
crushed, usually using a mortar and pestle or mixer and other equipment, the
petals are ground into fine particles for subsequent operation.
3. Quality control: before the preparation
of essential oil, quality control and testing is required to ensure that the
quality and purity of the raw materials meet the requirements.
4. Extraction of essential oil: Put the
crushed osmanthus petals into the extractor and add ethanol and other solvents
for extraction. The extraction time depends on the actual need, usually takes
more than a few hours. During the extraction process, the extractor can be
heated to increase the extraction speed.
5. Distillation: The extracted solution is
subjected to distillation, through which the water and other impurities in the
osmanthus flavor are separated out to obtain pure osmanthus essential oil. This
process should be very careful and cautious, pay attention to the distillation
time and temperature to ensure that the distillation process goes smoothly.
In the process of preparing osmanthus
essential oil, you need to use high quality osmanthus petals and other raw
materials, master certain preparation skills and operation methods, at the same
time, high quality and professional essential oil extraction equipment is also
essential.
Wenzhou Jinbang Light Industry Machinery
Co., Ltd. of the new multi-function stainless steel extraction tank: a variety
of styles and specifications, according to customer demand customized
solutions, factory direct sales, low temperature automatic extraction, high
efficiency and high quality, professional manufacturers, 30 years of research
and development experience, won the praise of customers.
Product Overview:
The extraction tank is filled with solvent,
soaked and then heated by jacketed steam. Tank liquid boiling, according to the
boiling point of each solvent is different, the beginning, the low-boiling
component first boil into a secondary vapor through condensation, cooling to
the oil-water separation, can be determined according to the process whether to
reflux or discharge. The oil-water separator utilizes the different densities
of oil and water to stratify the upper and lower layers, so as to obtain the volatile
oil. In addition, due to the heating process, there is a concentration
difference between the upper, middle and lower part of the liquid in the main
tank, so that the liquid can be recycled from the bottom of the main tank
through the filter and the pump back to the upper part of the main tank,
realizing dynamic extraction.
This equipment is suitable for
pharmaceutical, biological, beverage, food, chemical and other industries,
plants, animals, atmospheric pressure, pressurized, decoction, warm immersion,
hot reflux, forced circulation, percolation, aromatic oil extraction and
organic solvent recovery and other process operations, especially the use of
dynamic extraction or multi-canister countercurrent extraction better, shorter
time, high content of the liquid. Equipped with tanks equipped with CIP
cleaning automatic rotary spraying ball, temperature gauge, pressure gauge,
explosion-proof sight hole lamps, sight glass, quick-open feeding port, etc.,
to ensure easy operation, in line with GMP standards.
