supercritical co2 extraction lavender oil
The lavender oil with co2 extraction process has its own unique compound: Lavandulol
Lavender extract
Lavender is a perennial herb of the Lamiaceae family. It is native to the Mediterranean region and was later transplanted all over the world. Lavender was first published in Avicenna's "Medicine". It is used to treat chest and abdomen fullness, colds and coughs, dizziness, headache, palpitations, shortness of breath, and joint bone pain. Lavender leaves, stems, and flowers have a strong fragrance, strong and soft fragrance, no irritation, and no toxic side effects, and are widely used in medicine, makeup, washing, and food industries.
The vegetable oil extracted from lavender contains a variety of aromatic compounds and is an important natural fragrance. It is widely used in daily necessities, cosmetics, medicine, and other industries. The unique fragrance of lavender essential oil and its products has many functions such as repelling insects, deodorizing, antibacterial, calming and hypnotic, and relieving mental stress.
Lavender CO2 extract
The lavender oil with supercritical co2 extraction has its own unique compound: Lavandulol, which is found in abundance in the lab analysis of Lavender CO2 extract but almost zilch in its essential oil of other extraction methods.
This probably explains why Lavender CO2 extract smells exactly like fresh flowers! The color of the extract is champagne gold and thicker in consistency, unlike the essential oil of other extraction methods counterpart which is watery and clear in liquid.
The supercritical CO2 extraction process uses liquid CO2 to extract the most out of each plant, therefore resulting in the optimization grade with no form of oxidation and heat degradation of the final product.
Two lavender oil extraction processes
Lavender has a relatively high content of essential oils. Because of its aromatic smell, it is often used as a fragrance, insect repellent, and raw material for the preparation of fragrances. The extraction of lavender essential oil usually adopts the steam distillation method, it can also be made extract by solvent method and supercritical fluid extraction method.
Steam distillation
The yield of the steam distillation method is relatively low. The solvent method not only needs to remove the leaching solvent but also leaves the solvent and chemical substances contained in the product.
CO2 extraction
Supercritical CO2 fluid extraction process has high density, low viscosity, and high diffusion coefficient. It can quickly extract the essential oils in lavender at near-normal temperature. The process is simple and easy to operate, with high yield and no harmful chemical residues.
Steam distillation extraction method
Weigh 80g of lavender flower spike powder, soak it for 1 hour, and place it in a 1,000 ml three-necked flask. One port is connected to a steam generator, the other is connected to a straight condenser, and the condenser is connected to an oil-water separator.
The water vapor is passed into the flask, and the time is counted from the time when the distillate drips out, the lower water is separated through the oil-water separator, and the distillation is stopped after 3 hours, and the essential oils are collected. Combine the essential oils obtained from several experiments, add anhydrous Na2SO4 to remove water, weigh and calculate the yield, and refrigerate.
Lavender oil CO2 extraction process
The lavender flower spike powder is put into the extraction tank, the extraction pressure is 220bar, the temperature is 45℃, and CO2 is introduced at a flow rate of 20 L/h. After 120 minutes of extraction, the essential oil is released from the analysis tank. Combine the essential oils obtained from several experiments, weigh and calculate the yield, and refrigerate.
The primary and secondary relationship of factors affecting the yield of lavender essential oil extracted by supercritical CO2 is extraction time> extraction pressure> temperature> CO2 flow rate.
The optimized process conditions are extraction pressure 22MPa, temperature 45 ℃, CO2 flow rate *L/h, and time 120 min.
CO2 extraction VS steam distillation
Essential oils derived from the supercritical CO2 extraction of herbs are similar to the oils produced through distillation in that they can be used in aromatherapy and natural perfumery.
Oils derived from steam distillation vary in their qualities depending on the temperatures, pressures, and length of time applied for the process, but unfortunately, this process can’t extract heavier compounds. The CO2 extraction process might thus produce higher quality oils that have not been altered by the application of high heat, unlike the steam distillation process. In CO2 extraction, none of the constituents of the oil are damaged by heat.
Thus, the difference between traditional distillation and supercritical extraction is that instead of heated water or steam, CO2 is used as a solvent in the latter method. The supercritical extraction process operates at temperatures between 95 to 100 degrees F whereas steam distillation operates at temperatures between 140 to 212 degrees F.
In steam distillation, the molecular composition of both the plant matter and the essential oil is changed due to the temperature applied, this method can also damage volatile light terpenes due to the high heat. . On the other hand, a CO2 extract is closer in chemical composition to the original plant from which it is derived, as it contains a wider range of the plant’s constituents.
Steam distillation is the most popular way to create essential oil plant extracts, but high heat from steam can damage the plant’s chemical profile and steam concentrations can’t pull out the heavier plant chemicals like cannabinoids. But the supercritical CO2 fluid’s low temperature preserves the whole plant extract and can even pull out the heavy medicinal molecules like cannabinoids and carotenoids.
