Hot FAQ

  • Q Is caffeine soluble in liquid co2?

    A Supercritical CO2 helps act as a solvent to give the coffee bean solvent-like properties to dissolve the caffeine and extract it out of the coffee bean. Because it has a lower viscosity than liquid CO2, allowing it to move through and around the coffee bean more efficiently without too much pressure.
  • Q Is co2 extraction organic?

    A CO2 Botanical Extracts are completely natural and exceptionally pure. These highly concentrated plant extracts are free of solvent residues and impurities such as heavy metals. All CO2 Extracts are oil soluble.
  • Q Why is co2 better than ethanol?

    A CO2 is highly tunable. With CO2 you can vary factors such as time, temperature, and pressure to create different products.  Ethanol products need to go into more stages of refinement to be turned into various products such as distillate.
  • Q Does co2 extraction remove terpenes?

    A CO2 extraction is good for preserving terpenes because it is a cold separation process that can protect delicate plant compounds. Some methods may also use ethanol to help remove terpenes before fully extracting cannabis buds.
  • Q Is co2 extraction better?

    A CO2 extraction is also much better for the environment. CO2 gas is natural, so if it escapes into the air during  extraction it won't do any harm. It can also be recycled, making this method much more sustainable. Since the solvent isn't toxic, people working with this extraction method don't face any health risks.

Description of Perilla Seed Oil

Perilla Seed Oil, obtained from the mature seeds of Perilla frutesccns, a medicinal plant in the labiaceae family, is a kind of natural Oil with high unsaturation. Its main ingredient is alpha-linolenic acid, with a content of up to 67%, which is the highest content of this fatty acid among all natural vegetable oils found so far.

 

Perilla frutescens (L.) var. crispa), also known as Perilla frutescens (L.) var. crispa), is an annual herb in the labiaceae family. As a traditional medicinal and edible plant, it is one of the first 60 items issued by the Ministry of Health that are both food and medicine.


Perilla can be found in the wild and cultivated all over the country, with no strict requirements on light and temperature. It can grow well even in the wild mountains and wild areas, and the growing period can be long or short (3-4 months). It only takes a few days or weeks for vegetable consumption, and longer for the purpose of harvesting seeds.


Shaanxi and Gansu introduced Perilla early in China. Qingyang, Gansu has a history of 2000 years of cultivation. As one of the oil sources, Qingyang has rich Perilla resources.


Perilla leaves and shoots can be cooked, the ground part can be used as medicine, the seed can be pressed oil, as fertilizer.

The United States, Japan, Russia, North Korea, Indonesia and others have grown it as an oil crop.


Now Japan and South Korea have processed Perilla oil into natural health products to the market.

The effects of Perilla seed oil

1.     Hypolipidemic effect

Perilla oil can control platelet aggregation in human body, reduce neutral lipids in blood, remove cholesterol, and prevent thrombosis.

It is the vegetable oil with the highest content of A-linolenic acid among the known vegetable oils, and enjoys the reputation of "deep-sea fish oil on land".

2.     Improves memory and prevents Alzheimer's disease

DHA, which is synthesized from A-linolenic acid, is abundant in the cerebral cortex, retina and germ cells, promoting synaptic growth of brain nerve cells and improving memory.

3.     Anti-aging function

Perilla oil intake can significantly improve the activity of superoxide dismutase (SOD) in red blood cells, and has an obvious effect on delaying the aging of the body.

4.     Antiallergic

Perilla seed oil, can cause allergic three thin white substance and intermediate discharge of platelet aggregation activating factor (PAF) decreased significantly, which has lost sweet acid is a kind of acid compounds, anticoagulant, antibacterial anti-inflammatory, antiviral activity, has a strong resistance to oxidation inhibiting allergic reaction.

5.     Anticancer

Perilla seed oil can significantly inhibit the incidence of breast cancer caused by chemical carcinogen DMBA, and can also reduce the activity of omentonine decarboxylic acid in the colon. Inhibit the development of colon cancer.

6.     Lowering lipid and blood pressure

Rich linolenic acid in Perilla seed oil has a lower serum cholesterol, triglyceride, low density lipoprotein cholesterol (ldl-c) and very low density lipoprotein, inhibit thrombosis, prevent myocardial infarction and cerebral infarction, alpha linolenic acid also can reduce the blood viscosity, increase the blood oxygen uptake, inhibit the synthesis of triglycerides, increase the variety of lipid metabolism in the body, so the effect of Perilla seed oil lipid step-down particularly evident, especially more evident effect on hyperlipidemia and criticality of high blood pressure.

7.     Protect the liver

The alpha-linolenic acid in Perilla seed oil effectively inhibits fat synthesis and breaks down fat to expel it from the body. Daily consumption can prevent the formation of fatty liver.

8.     Strengthen brain and intelligence, and protect eyesight

Alpha-linolenic acid is one of the basic raw materials for the synthesis of nerve cells, and it is a key nutrient to determine the development of human intelligence. It is known as "brain gold". Correct supplementation of linolenic acid can increase the IQ of infants by 20%-30%, and pregnant women and children must be supplemented.

Difference between Steam Distillation & Supercritical CO2 Extraction

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. 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 35℃ to 50℃, whereas steam distillation operates at temperatures between 60℃to 100℃.

In steam distillation, the molecular composition of both the plant matter and the essential oil are changed due to the temperature applied. 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.

For example, CO2 Extraction of German Chamomile flowers yields a green extract, because the absence of heat means it was not altered from its natural state or “denatured.” The resulting extract is thus more similar in composition to the original flower than the distilled essential oils is.

CO2 extracts are usually thicker than their essential oil counterparts and often give off more of the aroma of the natural herb, spice, or plant than a distilled essential oil. CO2 extracts have been said to contain more plant constituents than the amount extracted from the same plant using steam distillation.


THE CO2 EXTRACTION PROCESS

·    Pressurized carbon dioxide becomes liquid while remaining in a gaseous state, which means it is now "supercritical." In this state, it is pumped into a chamber filled with plant matter.

·    Because of the liquid properties of the gas, the CO2 functions as a solvent on the natural plant matter, pulling the oils and other substances such as pigment and resin from the plant matter. The essential oil content then dissolves into the liquid CO2.

·    The CO2 is brought back to natural pressure and evaporates back into its gaseous state, while what is left is the resulting oil.

CO2_EXTRACTION

CO2 is colorless, odorless, and can be easily and completely removed by releasing the pressure in the extraction chamber. It is what we exhale and is needed by plants in order for them to thrive, which illustrates its harmlessness when employed in the extraction process. This absence of potentially harmful solvents in CO2 extraction means neither the human body nor the environment is polluted.
