What is Linoleic Acid Oil?

Alpha-linoleic acid is a clear to light yellow oily liquid that easily oxidizes in the air at room temperature. It has a melting point of -12℃ and a boiling point of 230℃ at 2.13kPa. This fatty acid is essential for the human body, as it cannot be synthesized in sufficient quantities to meet our needs. Both linoleic acid and alpha-linolenic acid are essential fatty acids that play a crucial role in human health. However, simply increasing the intake of linoleic acid without considering the ratio to alpha-linolenic acid can have negative effects on our health. When the intake ratio of linoleic acid to alpha-linolenic acid exceeds 4:1, it can lead to hyperlipidemia, hyperviscosity, and other related health issues.

Linoleic Acid Oil Uses

  1. Linoleic Acid Oil is a crucial fatty acid for both human and animal nutrition. Desaturase enzymes in both animals and plants can convert saturated fatty acids into unsaturated fatty acids, such as oleic acid. However, only plant cells have the ability to further convert oleic acid into linoleic acid. Linoleic acid is essential for the synthesis of animal prostaglandins and a deficiency in fatty acids like linoleic acid and linolenic acid can lead to stunted growth, skin and kidney damage, and infertility in animals. Additionally, linoleic acid can combine with cholesterol to form esters, promoting the degradation of cholesterol into cholic acid and lowering triglycerides. It is used in medicine to prevent and treat atherosclerosis and in various industrial applications such as the production of paints, inks, and surfactants.
  2. Linoleic acid is non-toxic and generally has no side effects when used as a hypolipidemic drug to treat and prevent atherosclerosis. Long-term use may cause gastrointestinal reactions, but these typically diminish with continued administration.

The Efficacy and Functions of Linoleic Acid Oil

  1. Required aspects
    Linoleic Acid Oil is an essential nutrient for the body and plays a crucial function in human wellness. When the human body does not have linolenic acid, it will certainly lead to various health issue. It can be seen that linolenic acid plays an important role.
  2. Improve intelligence
    Linoleic Acid Oil is useful for improving knowledge, preserving mind wellness and promoting brain advancement. It can boost people’s memory ability, believing ability, and stress and anxiety capacity. For the senior and youngsters, it can protect against brain signs and symptoms such as Alzheimer’s illness and advertise the renovation of youngsters’s knowledge.
  3. Advertise nutrient absorption
    Linoleic Acid Oil is beneficial to boost the absorption of numerous nutrients, such as minerals, vitamins, proteins and other nutrients. If there is a lack of linolenic acid, other nutrients can not be efficiently made use of and taken in by the body.
  4. Anti-cancer
    Linolenic acid also has anti-cancer effects, stopping the spread of cancer cells and triggering growths to shrink.
  5. Hypotensive
    Linoleic Acid Oil can minimize high blood pressure and blood lipids. It can decrease neutral fats such as cholesterol and triglycerides in plasma, thus efficiently lowering blood pressure.

Linoleic Acid Oil Production Method

Technique 1. Usage corn oil as resources
Prep work of unrefined linoleic acid product: Take the clarified corn oil, progressively add 200g/L salt hydroxide option, mix while adding, proceed mixing for 15 mins after including, allow stand at 25-40 ° C for saponification for 48 hours, take out the saponified item, Crush it into items with a wood shovel, slowly include 45% -50% sulfuric acid, and acidify at 30-40 ° C for 7 hours to get unrefined linoleic acid.
Corn germ oil [NaOH, 25-40 ℃] → Saponified product [H2SO4, 30-40 ℃] → Crude linoleic acid product Preparation of finished linoleic acid item Take the crude product into a separatory channel, include 2 times the volume of 30 ℃ tap water, shake, separate the water layer, repeat this 5-6 times, and after that wash with heated pure water till there is no sulfate, to obtain linoleic acid liquid. Add 100g/L anhydrous salt sulfate, drink well, and let stand at 25-30 ° C for 48-96 hours to get a refined item. The refined product is suction filteringed system, and the filtrate is the completed linoleic acid item.
Crude linoleic acid product [WATER, 30 ℃] → Linoleic acid fluid [Anhydrous Na2SO4, 25 ℃] → Linoleic Acid Oil refined item [Suction filtration] → Ended up linoleic acid product.

Approach 2: Use soybean oil feet as resources
Prep work of soap slurry: Take soybean oil scraps, warm to concerning 90 ° C, include a little 1/10 -1/ 7 times the quantity of sodium hydroxide option, continue home heating for 15 mins, after that add the remaining alkali option until the phenolphthalein indicator transforms purple., after that warmth and cook for 2-3h to acquire saponified product. Add 1/20 -1/ 10 times the quantity of industrial sodium chloride to the saponified material in 2 sets, and warmth up until the soap slurry does not stay with the blade when tasting with a shovel and there is evident black water speeding up, and then warmth for 1-2 hours. Keep it warm for 3 hours, then draw out the black water in the lower layer to get soap slurry
Fine-tuned oil deposit [NaOH, > 90 ℃] → saponification fluid [NaCl] → soap slurry.
To prepare black fatty acid, add the waste acid water removed from the very first batch of acidification to the soap slurry, warm it with steam for 30 minutes, allow it stand for 1 hour, essence the drainage, and afterwards gradually include 1/10 -1/ 7 times the quantity of concentrated sulfuric acid to When stratification happens, allow it represent 1 hour, extract the waste acid water from the reduced layer, and keep it for the following batch of acidification to acquire the acidification fluid. Add 3 times the quantity of clean water to the acidification option, heat the steam to over 80 ° C for 20 minutes, let it represent 30 minutes, drain the drainage, and repeat the procedure 3-4 times until the pH worth of the waste water gets to 6-7 to get black fatty acid
Soap pulp [H2SO4] → Acidifying fluid [WATER, > 80 ℃] → Black acid.
Preparation of unrefined linoleic acid: Heat guanoic acid to about 105 ° C, draw it right into the purification tower in batches, and distill under lowered pressure. The temperature of the biphenyl heating system is 270-290 ° C, the stress is 49-117.68 kPa, the vacuum cleaner degree of the distillation tower is above 99.75 kPa, and the gas stage Temperature 190-200 ℃. 1.5 hours each time, vapor out the blended fats and add black feet when. Freeze the blended fatty acid to regarding 0-2 ℃, take it out and placed it into a damp fabric bag and press it with a hydraulic press. Gradually boost the pressure to 14.71 MPa and press for 10-12 hours. The ejected fluid is unrefined linoleic acid, and the strong matter left guaranteed is stearic acid.
