Flaxseed oil is made from flaxseed, which is a flax seed. It belongs to the family Flax, also known as flax. Because it is native to the East India region, when the Han Dynasty moved to the Western Region, it brought the linen back through the Silk Road. China, mainly planted in the old Xiongnu area, is the area where the "Hu people" gather, hence the name. Flaxseed is a traditional oil crop in China. Flax is divided into oil flax, oil fiber flax and fiber flax. Oil flaxseed is mainly produced in the Songnen Plain of Changbai Mountain and Heilongjiang Province, Inner Mongolia, and Liupan Mountainous Area of Ningxia. Zhangjiakou Dam is on the north. Although flax has anti-barren habits, as oil flax, "cold climate, abundant soil, and sufficient light" are indispensable. Xinjiang, Gansu, Ningxia, Inner Mongolia, Shanxi and other places, also known as sesame oil, mainly due to the introduction of the Middle East into China. Cold-pressed linseed oil is rich in alpha-linolenic acid and is the most effective way to supplement linolenic acid.

Basic Information

Flax originates from the Middle East and the Mediterranean coast and is an annual herb. The consumption of flaxseed dates back to Mesopotαmiα in southwest Asia 5,000 years ago. Around 650 BC, Hippocrates, the father of ancient Greek medicine, documented the medical use of flaxseed. In the Han Dynasty, when Zhang Wei was sent to Dawan, he brought flaxseed from the Western Region into the northwestern regions of China, Inner Mongolia, Ningxia, etc., so it was also called flax. The linseed oil that people call is flax oil. Flaxseed oil is divided into cold pressed and hot pressed.

There are mainly seven sources of flaxseed in China: Ningxia, Gansu, Inner Mongolia, Qinghai, Xinjiang, Heilongjiang and Yunnan. In order to evaluate the quality of flaxseed medicinal materials from different regions, the researchers in China used α-linolenic acid and linoleic acid as indicators to determine the content of flaxseed in six producing areas by gas chromatography to determine the most flaxseed. Good place of production. Results The average content of α-linolenic acid and linoleic acid in the samples of 6 producing areas was 45.17% and 21.19%, respectively. Among them, the content of α-linolenic acid and linoleic acid in the flaxseed of Gansu was the highest, reaching 56.30% respectively. 25.70%. Flaxseed oil is especially beneficial for pregnant women and infants, so linseed oil is also commonly known as moon oil and smart oil.

Nutritional analysis

The ratio of ω‐3 series (α-linolenic acid) to ω‐6 series (γ-linolenic acid) in unsaturated fatty acids in flaxseed is close to (4-6):1.

Flaxseed oil contains 18 kinds of amino acids, of which the amino acid content is more than 5% of the protein content, followed by glutamic acid (26.3%), aspartic acid (12.5%), arginine (11.8%), glycine. (7%), leucine (6.8%), tryptophan (5.8%), alanine (5.4%), phenylalanine (5.3%), isoleucine (5.2%).

Processing technology

A major feature of linseed oil is low temperature processing to ensure maximum retention of nutrients. This is also a major feature distinguishing the common edible oils in the market. The following are some of the introductions to the processing of edible oils.

Two basic manufacturing processes for edible oils: leaching, pressing, and subcritical cryogenic extraction.

1. The difference between the two methods of leaching method and pressing method is that the leaching method uses solvent oil (No. 6 light gasoline) to soak the oil and fat materials after high temperature extraction, and after the “six off” process (ie, degreasing and degumming) It is processed by dehydration, decolorization, deodorization and deacidification. The advantages are high oil yield and low production cost, but it is processed by fat, degumming, dehydration, decolorization, deodorization and deacidification. The advantage is that the oil yield is high. Produced to seriously damage the nutrients in the oil during processing. The pressing rule is to separate the oil directly from the oil by physical pressure. The whole process does not involve any chemical additives. It is divided into hot pressing method and cold pressing method. The hot pressing needs to fry the raw materials, and the cold pressing is directly processed under natural conditions. . The cold pressing method can ensure the safety and hygiene of the products and the natural nutrition is not damaged. It is the most ideal processing method. However, the oil yield is low and the cost is high. Most of the oils on the market are mostly leaching oil.

2. Subcritical low temperature extraction method: This method is to process the flaxseed in a closed system of no more than 40 degrees, and completely retain the nutrient composition of the linseed oil. In addition to the advantages of the cold pressing method, it also has a high oil yield, can be industrialized on a large scale, and reduces waste of resources.

Through research and clinical experiments, it has been confirmed that linseed oil has the following functions:

1. Skin is delicate and shiny

Improves skin's fat content, leaving skin smoother, moisturized, softer and more elastic, while allowing skin to breathe and sweat properly, alleviating various skin problems.

2. Lose weight

 It can consume excess body fat and is a healthy diet.

3. Improve women's premenstrual syndrome

There are many examples of premenstrual syndrome in women, such as dysmenorrhea, and the symptoms disappear completely after eating fresh linseed oil every day. Of course, vitamins and minerals are needed.

4. Improve resistance to stress

Omega 3 reduces the effects of harmful biochemicals produced by stress on the body, stabilizes mood, maintains a calm mind, and reduces depression and insomnia.

5. Alleviate allergic reactions

Omega 3 can help alleviate allergic reactions, but because the whole body has to be reorganized, it takes a long time to completely eliminate allergies, and more comprehensive nutritional support.

6. Reduce asthma

It can significantly reduce asthma attacks after eating for a few days.

7. Improve arthritis

Experiments have shown that omega 3 has a great effect on the treatment and prevention of arthritis. 60% of patients with rheumatoid arthritis can stop using non-steroidal anti-inflammatory drugs after receiving omega 3 and 6 fatty acids, while another 20% can halve non-steroidal anti-inflammatory drugs.

8. Improve inflammation of organ tissues

Omega 3 is very helpful in preventing inflammation of organ tissues, including meningitis, tendinitis, tonsillitis, gastritis, ileitis, colitis, arteritis, phlebitis, mastitis, nephritis, spleen, Hepatitis, pancreatitis, otitis, etc., as well as sputum and sores.

9. Lower cholesterol

Omega 3 reduces blood cholesterol by 25% and triglyceride by 65%, and converts excess low-density cholesterol (LDL) into bile acid for excretion.

10. Reduce heart load

It can reduce high blood pressure, reduce blood lipid levels, increase the level of unsaturated fatty acids, improve blood concentration, reduce blood viscosity, maintain blood flow, prevent vascular obstruction and related diseases. In addition, it can prevent blood from clotting, prevent stroke (cardio-cerebral artery occlusion), heart disease (heart artery blockage), pulmonary embolism (pulmonary artery blockage), and vascular surface disorders (ie, acne).

11. Improve stagnant water

Help the kidneys to remove sodium and water. Hydrosis usually occurs in swollen ankles, overweight in certain situations, premenstrual syndrome, late cancer, and cardiovascular disease.

12. Improve kidney function

Omega 3 adjusts prostaglandin (Prostaglandin) to promote the secretion of liver, pancreas and spleen, so that the body's metabolism is working properly.

13. Improve constipation

Improve intestinal function, increase absorption capacity, increase intestinal peristalsis ability to make bowel movements normal, reduce constipation.

14. Promote cell health

Improve the moisture and elasticity of the cell membrane, increase the function of cell respiration and nutrient exchange, and strengthen the ability of body cells to repair and heal, make the cells healthy and reduce the chance of cancer.

15. Promote brain flexibility

Increase the brain delivery medium (Neurotransmitter), strengthen the brain activity function, make the brain function more effectively, and learn and think better.

16. Energetic

Balance and improve your body's blood sugar levels to make you more energetic. It can also increase the stamina of the muscles, and it can make the fatigue muscles recover faster after exercise.
