This experiment is for extracting oil from drying perilla seeds by using supercritical CO2 extraction machine.
Crush the drying perilla seeds into 20-40 mesh powders, and put the powders into extraction cylinders.
Setting the values, extraction temperature is about 40ºC, pressure is 30MPa, and separating temperature at 45 ºC and pressure at 6MPa, extraction time 3-4hours, extraction rate is about 45.8%, features high output rate. Obtained oil is a high-quality health-care one.
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.
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.
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.
