Question 2: What is the taste of linseed oil? Self-identification of linseed oil and olive oil;
Put linseed oil and olive oil in the freezer 10 hour or more, and take them out for observation:
1) If the content of unsaturated fatty acids in uniform pickling is low, it may be adulterated;
2) If a small amount of olive oil solidifies, the solidified product is irregular and normal, so the purity of olive oil is high;
3) Flaxseed oil is waxy if it has cotton wadding-like suspended matter, and this substance is "wax";
4) Flaxseed oil will become "slightly bitter" after the summer from June to September. Linseed oil will not be "slightly bitter" without summer. If it is slightly bitter, it belongs to mild oxidation.
Identification method of cold pressed linseed oil: the taste of cold pressed linseed oil is "oily"; Refined linseed oil has a fishy smell.
Identification method of waxy linseed oil;
Put linseed oil in the freezer 10 hour or more, and take it out for observation:
If there is a cotton-wool suspension, it is waxy linseed oil with linolenic acid content less than 50%; If cotton wool-like suspended matter appears, it is dewaxed linseed oil with linolenic acid content of not less than 50%.
Attachment: Hazards of Waxy Linseed Oil:
1. Regular intake of "wax" will attach to gastrointestinal mucosa and cause indigestion. "Wax" is a highly saturated fat, and long-term intake will lead to an increase in blood lipid and blood pressure. "Wax" is no less harmful than hydrogenated oil.
2. Practice has proved that if you continue to eat linseed oil containing "wax" for one and a half to two years, your blood lipid and blood pressure will increase obviously, and it is not easy to decrease.
Question 3: What is linseed oil? Is it cooking oil? Flaxseed oil is an oil made by pressing flaxseed. Flaxseed is a traditional oil crop in China. Flaxseed oil extraction has a history of more than 600 years in China. At present, it is mainly introduced in China: North China and Northwest China, with the largest output in Inner Mongolia, Shanxi, Gansu and Xinjiang, followed by Jilin, Hebei, Shaanxi and Qinghai, and sporadic planting in Xigeng, Yunnan and Guizhou in the southwest. It is an important cash crop and main oil crop in China. Flaxseed oil is rich in A- linolenic acid, which is a good way to supplement linolenic acid.
Note: Flaxseed oil is especially beneficial to pregnant women and babies, so flaxseed oil is also commonly known as moon oil and smart oil. But also contains 16 effect, in which improving skin fat content means soft and shiny skin, healthy weight loss and so on.
Question 4: What is linseed oil extracted from linseed? Just like sesame oil squeezed from sesame seeds and peanut oil squeezed from peanuts. Flaxseed is generally produced in alpine plateau areas. For example, central and western Inner Mongolia, northwestern Shanxi, Ningxia, Gansu and so on.
Question 5: What is the difference between linseed oil and common blended oil? Flaxseed oil is rich in ω-3 series polyunsaturated fatty acids, mainly α -linolenic acid, which is an essential fatty acid for human body and cannot be synthesized in human body. Must be supplemented from food. The main components of other edible oils are saturated fatty acids and monounsaturated fatty acids. Eating this kind of oil for a long time and absorbing too much saturated fat will cause adverse reactions and side effects. Suqian Nong Sanpin linseed oil. Com is very good. You can buy it if you want. There seems to be activity in the mall recently.
Question 6: What kind of oil is linseed oil? How to distinguish flaxseed oil from quality is as follows:
First look at the place of origin. People familiar with linseed oil generally know that the highest linolenic acid content is only linseed planted in Inner Mongolia; Followed by Ningxia; Followed by some plants in Shanxi and Hebei (these two provinces are only planted in several counties near Inner Mongolia); The flax seeds in Northeast China are suitable for producing chemicals and flax mats.
Second, look at the production process. There are generally three production processes of linseed oil: cold pressing, hot pressing and leaching. The best is the real cold-pressed linseed oil, which is carried out at room temperature and does not need heating; Hot pressing is the oil squeezed out after high temperature baking; Leaching is the process of soaking flaxseed in No.6 hydrogen oil, squeezing, and then dewaxing, decoloring, degumming, deacidifying, derusting and deodorizing, which is called "refining". Generally, the oil produced in this way is used as industrial oil.
Third, depending on the color, the color of oil is naturally different with different production processes. The real cold pressed linseed oil is golden yellow in color; Hot-pressed oil is dark red, also called chestnut; The oil after leaching and refining is light yellow, and some of them are close to the color of salad oil.
Fourth, smell the taste, the real cold-pressed linseed oil is a deep taste, and the boutique has a faint grass fragrance; Hot pressed oil is completely fragrant, just like the smell of roasted flax seeds; Leached oil is a fishy smell, which many people say is actually the smell after leaching and refining.
5. Looking at the packaging, according to many cases and nutrition experts' explanations, the plastic packaging of food has very unfavorable factors to the human body, especially the oil in plastic packaging, even if it meets the food safety standards, it will inevitably decompose with edible oil. In other words, the edible oil or linseed oil in plastic packaging, plastic components plasticizer and plasticizer will definitely decompose into oil, and the serious consequences of long-term consumption of plastic packaging can be imagined. The best packaging is opaque glass bottle packaging, which not only avoids the problem of oxidation, but also preserves the original activity of linseed oil more completely.
6. Look at the price. The price of your linseed oil in the market ranges from a dozen to several hundred. Authentic domestic pure natural flaxseed raw materials 25 yuan about a catty, cold-pressed flaxseed oil about 5 jins.
Question 7: What's the difference between linseed oil and olive oil? Linseed oil is a functional edible oil, which is not suitable for high-temperature frying, but it is indispensable to human body. Rich in linolenic acid, it can synthesize EPA and DHA necessary for human body, which can not be synthesized by other edible oils. Olive oil is an outsider in China. It is made by squeezing the fruit of olive. Olive oil is an important raw material for western food. Olive oil is also a beauty slimming product. This is because olive oil contains more than 80% monounsaturated fatty acids, which can protect skin and improve skin quality. However, this acid is not the most lacking acid in human body. If there is more oleic acid in the body, it will not do any harm to the body, but the content will not have any big impact on health. Linseed oil is linseed oil. Flaxseed oil is divided into two methods: hot pressing and cold pressing. Whether it is hot pressed linseed oil or cold pressed linseed oil, the raw material is the same: flax. In real life, all the oil we eat is hot pressed. Hot-pressed linseed oil, also known as linseed oil, is to fry linseed at high temperature and then press it, which improves the oil yield, but destroys the original nutritional component (α-linolenic acid), improves the acidity, and is darker in color but more fragrant in taste. In recent years, with the improvement of people's living standards, people pay more and more attention to health, and cold-pressed linseed oil is increasingly favored by people. Relatively speaking, cold-pressed linseed oil is the top grade of linseed oil because of its advanced technology and better retention of nutrients. Cold pressed linseed oil retains the natural flavor and color of flax, and completely retains various nutrients. Cold pressed oil is authentic and authentic, which is the choice of healthy life. Especially pregnant women and babies. The contents of linolenic acid, linoleic acid and oleic acid in polyunsaturated fatty acids of linseed oil are 53%-57%, 15% and 20% respectively. ω-3 is one of the main components for repairing cell membrane, and it is an essential fatty acid for human body, which cannot be synthesized by human body and can only be absorbed in food. The content of omega-3 in cold-pressed linseed oil is the highest among all foods, which plays an important role in human health. The living conditions and diet of China people now determine that the content of linolenic acid in human body is extremely scarce, but the content of linoleic acid is very high, which leads to a serious imbalance in the ratio of these two essential fatty acids, and the ratio of oleic acid, linoleic acid and linolenic acid in linseed oil is the most suitable ratio advocated by Nutrition Society. The ratio of linolenic acid to linoleic acid is close to 1:4, and linolenic acid is converted into dha and epa in human body. These two substances have good effects on human brain and visual organs, and linseed oil is an edible oil with good therapeutic effect. Among the many producing areas of linseed oil, Inner Mongolia prairie is the best, where the air is good, the soil is good and there is no pollution. The flax seeds planted in this way are of high quality, and the extracted oil is natural and healthy. Regular consumption of Mengguxiang linseed oil has the functions of increasing intelligence, protecting eyesight, lowering blood fat and cholesterol, delaying aging and resisting allergy. It is better to buy an affordable flaxseed oil than an imported olive oil. Flaxseed oil is the best and most needed for health.
Question 8: The difference between linseed oil and olive oil. Linseed oil is obtained from flax seeds.
The oil content of whole flaxseed is between 29% and 44%, and the shell content is between 20% and 45%. The shell also contains about 17%-20% of oil, so flaxseed is generally not shelled when making oil.
Linseed oil is golden yellow, and linseed crude oil is dark amber with special smell. This smell is not only caused by volatile impurities in oil, but also because oil contains more highly unsaturated fatty acids. Deodorized linseed oil has a aftertaste. Fresh linseed oil is edible.
Olive oil is an excellent non-drying oil. It is one of the most important and oldest oils in the world. the Mediterranean Sea
People in coastal countries widely eat this oil. Olive oil comes from the fruit of the evergreen olive tree. The whole fruit contains 35%-70% oil (dry basis), and the pulp contains more than 75% oil. The shape of olive oil is closely related to the oil-making process. High quality olive oil can only be made by cold pressing, and it needs to be separated from low pressure to high pressure. The olive oil obtained by low pressure head can be eaten without refining. Oil is yellow-green, with a particularly mild and lovely fragrance and taste. Moreover, the acid value is low (generally 0.2-2.0), and it is still transparent at low temperature (close to 10℃). Therefore, low-pressure olive oil is an ideal cold oil and edible oil.
Olive oil is the best edible oil, but each oil has the advantages of various oils, so it is suggested to mix it reasonably.
Aobolan olive oil imported from Australia is quite good, with acidity ≤0.3, unsaturated fatty acids above 80%, and physical cold pressing for 8 hours.
Question 9: What is the composition of linseed oil? Flaxseed oil is rich in A- linolenic acid, which is a good way to supplement linolenic acid.
The total content of crude protein, fat and total sugar in flaxseed is as high as 84. 07%. Flaxseed protein has a complete range of amino acids, and the content of essential amino acids is as high as 5. 16%. It is a plant protein with high nutritional value. The content of α -linolenic acid in linseed oil is 53%. α -linolenic acid is an essential fatty acid for human body, which can be converted into eicosapentaenoic acid and docosahexaenoic acid in human body. They are effective active ingredients in fish oil. α -linolenic acid has the functions of anti-tumor, antithrombotic, hypolipidemic, nourishing brain cells and regulating autonomic nerves, which has attracted more and more attention. Flaxseed contains a lot of polysaccharides, which has the functions of anti-tumor, anti-virus, anti-thrombosis, reducing blood lipid and so on.
Flaxseed oil also contains VE, which is a powerful free radical scavenger with anti-aging and antioxidant effects. Flaxseed contains 23 mg/100 g of flavonoids, which have good hypolipidemic and anti-atherosclerosis effects. The content of unsaturated fatty acids in linseed oil is very high, and its iodine value is also high, so it is necessary to add antioxidants or nitrogen to seal it when storing. The unsaponifiable matter of linseed oil is 8. It shows that linseed oil contains a large number of higher fatty alcohols, sterols and hydroxyl groups. Flaxseed is rich in mineral elements. The content of potassium is the highest, much higher than that of oranges, peanuts and shrimps with high potassium content. Potassium is related to maintaining normal blood pressure, and the content of zinc in flaxseed is also high. Zinc is an essential trace element for human body and plays an important role in maintaining normal physiological functions of human body.
Question 10: What are the side effects of linseed oil? Flaxseed is a cholesterol-free substance, like flaxseed oil I eat, which is rich in fiber and N 3 fatty acids. N 3 fatty acids contain nutrients, which help to prevent heart disease and other chronic diseases and will not have side effects on human body. Its main function lies in the following fifteen points.
First, the skin is delicate and shiny;
Second, lose weight;
Third, improve female premenstrual syndrome;
Fourth, improve the ability to resist pressure;
Fifth, reduce allergic reactions;
Sixth, reduce asthma;
Seventh, improve arthritis;
Eight, lower cholesterol;
Nine, reduce the heart load;
Ten, improve water stagnation;
XI。 Improve renal function;
Twelve, improve constipation;
Thirteen, promote cell health;
Fourteen, promote brain flexibility;
Fifteen, full of energy.
