Mint essential oil, is the ingredient extracted from Mint at low temperature. Mint flavor is refreshingly cool and invigorating to the mind. It is very effective in clearing the throat and eliminating bad breath, and has a unique healing effect that soothes the mind and body.
There are two common extraction methods for
Mint essential oil:
1. Water vapor distillation
Water vapor distillation is a common method
of extracting essential oils from plants, distillation equipment with a large
volume, and easy to operate, low cost, is the main method of extraction of
essential oils of flowers, herbs and teas. This method is suitable for
volatile, can be vaporized with water vapor without being destroyed, and water
does not react, but also difficult to dissolve in water for the extraction of
active ingredients.
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 needs to pay
attention to the control of temperature and time, to ensure that only the pure
aroma of mint extracted components.
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 extracted liquid or decompression
distillation, such as removing the solvent can be 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 will be dissolved in ethanol, low-temperature
filtration to remove impurities; and finally, evaporation of ethanol to get the
essential oil.
The following is a detailed description of
the preparation process of Mint essential oil.
1. Preparation of raw materials: prepare
high-quality Mint, cooking alcohol, distilled water, etc. in advance, wash the Mint,
dry.
2. Crushing: Crush the mint, usually using
a mortar and pestle or blender and other equipment, grinding into smaller
particles for subsequent operations.
3. Quality control: Before the preparation
of essential oils, quality control and testing are required to ensure that the
quality and purity of the raw materials meet the requirements.
4. Extraction of essential oil: Put the
crushed Mint 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 Mint
flavor are separated out to obtain pure Mint essential oil. This process should
be very careful, pay attention to the distillation time and temperature to
ensure that the distillation process is carried out smoothly.
In the process of preparing Mint essential
oil, you need to use high quality Mint 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 needs tailored 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, pressurization, decoction, warm
immersion, thermal 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.
