Linseed oil term. In a closed bottle

Here is a selection of some harmful properties linseed oil. Pay attention to some negative properties may be serious.

1.Rapid oxidation spoils the product and leads to fire

Linseed oil not intended for heat treatment, as it is subject to rapid and severe oxidation. This happens when interacting with air and the process accelerates when heated.

Oxidation produces harmful free radicals. Therefore, you can not fry on it or add to hot food. You can't store it in outdoors, in an open container. Store only in the refrigerator.

If the conditions and terms of storage are violated, the oil will go rancid. Due to the presence of ketones, epoxides and aldehydes in rancid oil, it should not be eaten.

For the curious: oil is a liquid continuous medium, with a molecular weight of 450-500 and a density of 0.9, we get a mole of about 0.5 liters. For the addition (complete oxidation) of 1 double bond, 22.4 liters of oxygen = 100 liters of air are needed. In this case, everything must be mixed well. A half empty 0.25 L bottle contains 125 ml of air, or about 0.01 mole of oxygen. 125 ml oil = 1/4 mole. Therefore, the limiting oxidation state = 4%. Too much! Conclusion, you need to buy oil in a small container.

For the curious: Linseed oil spontaneously polymerizes in the open air with an exothermic reaction. A cloth soaked in oil may ignite spontaneously.

2. sunlight will ruin the oil

Linseed oil deteriorates from exposure to direct and indirect sun rays. Therefore, it must be stored in a dark place, and it is desirable to purchase it in a darkened container. Otherwise, the body will receive harm, not benefit.

3. short shelf life even in the refrigerator

After opening the bottle, the shelf life of healthy linseed oil is 1 month. The sooner it is eaten after opening, the less likely it is to saturate the body with free radicals instead of useful omega-3 acids.

Tip: buy products well-known manufacturer and pay attention to the expiration date.

4. harm of linseed oil for women

Although there are not many specific harmful properties, it is still better to know about them. Here is a description of the harmful qualities of flaxseed oil for women's health.

5. excessive consumption

There are no specific recommendations for this. The product usually does not cause allergies, and its overdose does not threaten serious side effects. The main harm from overconsumption flaxseed oil is that it causes loose stools.

Excessive consumption of oil can harm the following categories of people:

• pregnant women;
• nursing mothers;
• suffering from hormonal imbalance.

It is worth noting: flaxseed oil contains phytoesrogens that duplicate the hormone estrogen.

6. if there are stones

Contraction of the muscles of the urinary and biliary tract can lead to the infringement of the stones present in them. This will cause an attack of pain at the site of infringement. Therefore, people with stones in the organs should use pure form flaxseed oil (like any other vegetable oil) is not worth it or should be done with extreme caution.

7. harm from flaxseed oil when taking medication

Flaxseed oil can be harmful to people who use painkillers, as well as certain drugs for lowering blood pressure, lowering cholesterol, and against diabetes. People taking blood thinners should also avoid flaxseed oil, as it prevents blood from clotting.

The use of the product is contraindicated for those taking antiviral drugs and antidepressants, as well as for women using oral contraceptives. Avoid using flaxseed oil if you are taking laxatives.

In any case, when taking medications and with chronic diseases, you should consult your doctor. Perhaps you need a special diet and there will be no place for linseed oil in it.

Flaxseed oil can also be used in salad dressings, and added to homemade hair masks and skin care products. But how to store linseed oil after opening it, because then its shelf life is reduced, and useful qualities quickly disappear. Let's figure out how to properly store flaxseed oil and how to use it.

Features of storage of linseed oil

Flaxseed oil is a storehouse of vitamins and useful substances. Beneficial features of this product are achieved thanks to the content:

• a large amount (in percentage terms) of unsaturated fatty acids Omega-3 (lanolin), Omega-6 (linoleic) and Omega-9 (oleic);
• B vitamins, including folic acid, C, F, vitamin E (tocopherol) and phytohormones, analogues of female estrogens.

Flax seed oil is used in many areas:

• in industry - for the manufacture of paints and varnishes and floor coverings (linoleum);
• in cosmetology, including for the preparation of home care products with their own hands;
• V folk medicine and dietetics;
• as food additive general strengthening and preventive action.

Dishes with flaxseed oil are popular with those who adhere to the rules of a healthy diet, follow the figure and prefer to use only natural products. But can you cook with flaxseed oil?

This product must not be heated or heat treated as epoxides, aldehydes, carcinogens and other compounds are released after exposure to heat. Eating food fried in flaxseed oil is dangerous.

Storage methods: 5 rules

The instructions supplied by the manufacturer with each flaxseed product contain information on use and describe optimal conditions storage of linseed oil.

After purchase, linseed oil is stored in the refrigerator at a temperature of about 5 ° C. You can also place the bottle in the refrigerator door, but the container must be made of dark glass and tightly closed.

Such strict requirements are due to some features of the product. For example, it is associated with the following properties:

• When in contact with oxygen a polymerization process occurs when a dense film of sticky fatty acid molecules forms on the surface. Of course, all useful qualities in this case will be lost.
• Under the influence of heat and sunlight rancidity of the oil and the release of harmful substances.

It is better to use dishes with linseed oil dressing immediately after preparation, because after half an hour irreversible processes start, the product rapidly loses all its valuable qualities while changing the taste and smell. If the oil is bitter, then it is better to refuse to use it.

What are best ways storage and where to store linseed oil after opening?

Image	Description
	Rule 1 It is good if the bottle is made of dark green or brown glass. If the product was purchased in plastic container or a transparent bottle, it must be poured.
	Rule 2 The bottle must always be tightly closed. Do not store oil without a lid. The ideal option is a lid with a dense plastic or natural cork. It is extremely important to minimize contact with air so that the product does not deteriorate.
	Rule 3 Optimum storage conditions - in the refrigerator. In a place where it will not freeze and crystallize. You can also hide the bottle in a kitchen cabinet or cellar, as long as it is cool (up to 23 °C) and dark. The shelf life directly affects the useful qualities of the product, so it is important to observe the temperature regime.
	Rule 4 For oil, it is better when there is no light at all. A dark and cool place - a nightstand, locker or cellar - is what you need.
	Rule 5 Do not forget that the shelf life of flaxseed oil shortens after opening the bottle. If pronounced rancidity is felt, the expiration date has expired, and the product is not suitable for internal use.

It is advisable to purchase linseed oil in small dark glass bottles with tight lid as in the photo. The likelihood that you will spend liter container in pretty short term- minimal, but small containers are easier to store.

Manufacturers may provide different information about expiration dates. But usually the shelf life after opening does not exceed a month (30 days). Ideally, the contents of the bottle should be consumed within two weeks.

The shelf life of oil in its original packaging without integrity damage can vary from six months to 12 months. Therefore, when buying, choose the bottle whose contents are “fresher”.

Where to use expired flaxseed oil? Unfortunately, like any spoiled product, it will have to be thrown away. Some manage to use it as a component of hair masks, but you should not expect a positive and healing effect.

Conclusion

Beautiful appearance And good health- the price of a proper lifestyle and healthy nutrition. The use of linseed oil in food and when creating homemade cosmetics self-care is extremely useful, because rare product boasts such a rich composition.

Maximum saving of all useful qualities during the entire shelf life is achieved if the storage conditions are observed. I talked about this in detail. The video in this article will reinforce the words with visual instructions. And if you have any questions, please leave them in the comments.

Good afternoon, dear readers! Today Vladimir Zuykov is with you again, and I have prepared a very interesting article about how to choose the right flaxseed oil, how to store it and eat it. You will also find an interesting crossword puzzle on this topic.

Since it is winter, I often get asked about warming up and increasing the calorie content of food in order to fill up. So here it is the right oils, one of which is flaxseed, can help with these issues. There is a lot of information, so let's talk about everything in order.

What is the use of the product and why is it needed?

What I am about to tell you, many do not know, and for good reason. There are many different oils, but I will say right away: some are worth using, while others are not.

Flax fats are very necessary for our body, in particular for good blood circulation. Know that if the blood flows well through the vessels, you will freeze many times less - that's the whole trick.

Regular use of flaxseed oil has the following benefits:

How to choose a good linseed oil?

I'll tell you right now, choose good oil need to be able to. Just to come to the store and buy the first thing that comes across is stupid and extremely reckless. In most cases, you will get harm from such a product, not benefit.

Because I have already bought it dozens of times, I have decent experience in this matter, I will reveal to you the subtleties of his choice. So here you go step-by-step instruction by choice as I do.

1. The container in which the product is poured

When I buy linseed oil, and indeed any, I first of all pay attention to the container in which it is poured. I will not even go near the oil poured into a light plastic bottle.

Guys, this is generally a tin! What does a manufacturer who pours a product into plastic, especially transparent, think? PET reacts with light fats in flaxseed oil to form harmful compounds. But that's not all! In such a container, additionally, under the action of sunlight and air, the oil is oxidized, becoming unhealthy.

Therefore, I recommend always buying flaxseed oil in glass container. If it is a transparent bottle, then outside it should have a cardboard box so that it does not get sunlight. Sometimes it can be found in a dark glass bottle - this is also a good option.

2. Is it cold pressed?

Manufacturers often make the product in violation of cold-pressed technology. You can write anything on the label and there is no way to check it. For example, that it is squeezed out at 42C, but in fact the press can be heated up to 85C! This is done to increase the yield of the product. Will this be useful? NO!

Flaxseed oil cannot be heated, it produces harmful carcinogens. Squeezed out in this way refers to products that are not raw food, but are used by “raw foodists”.

3. Dilution with cheap oils

Cheap flaxseed oil is usually worth every penny because it is not 100% flaxseed. Cunning manufacturers dilute it with another oil, most often corn or rapeseed to hide the effects of excessive heat when squeezing flaxseed.

In addition, such a product is often poured into dark plastic bottles 0.5 and 1 liter each, so that the buyer could not immediately understand what was happening.

4. Proper shelf life

Look at the date of manufacture and the expiration date. Flaxseed oil can be stored for 6-9 months in a very sealed bottle and in a completely dark package.

If the bottle has a shelf life of 18 months, it's chemistry. I am already silent that some manufacturers can store it for 2 years. Just tin! What do they put in there?

5. Taste and smell of the product

Good flaxseed oil always has a slight bitterness (but not bitterness) and a slight aftertaste. fish oil but does not smell like fish. These factors indicate a normal non-oxidized state fatty acid Omega-3, which, as you already know, is very abundant in flaxseed oil.

Know that bad flaxseed oil will never taste like this. Often cheap oil does not have a pronounced taste and smell, which is abnormal and indicates its low quality.

I note that if it even has a slight aftertaste roasted sunflower seeds, so it was not made by cold pressing, but by the method of industrial extraction (to reduce the cost of production).

6. Correct tare volume

No need to take in a large container of 1 liter. This impairs the ability to store it. The fact is that after uncorking the container, it is stored for a maximum of 3 months, and then it usually goes rancid and can no longer be eaten.

If you use linseed oil alone, take it in small bottles of 0.2 liters or 0.35 liters, they are usually made of glass.

7. Color and sediment at the bottom

Quality flaxseed oil is golden brown in color and has a slight sediment at the bottom of the bottle.

If the color is light and there is no sediment, we are also dealing with a refined product, which is not always good for health. Refining is often carried out using edible gasoline. We do not need such a surrogate.

If the product has a pronounced orange tint, then it is not cold pressed, but a hot press was used to extrude it. It already contains practically no useful omega-3 fatty acids, but only carcinogens.

Where to buy quality linseed oil?

If you are an ordinary consumer, it is quite easy to buy flax seed oil in a supermarket, store or pharmacy. But as you already understood, it is of low quality there and is not suitable for a healthy diet. Therefore, alternative sources must be sought. So where to buy best oil flax and which one to choose?

Option number 1

try various oils from manufacturers available for sale, choose the best. It is good if you are advised by experienced friends from your city.

I went this route and found only one good manufacturer out of several available in my town. For the rest, it is unsuitable for food or a surrogate. I don't recommend this method!

Option number 2

To buy the best, you need to start useful contacts with people who 100% make the product with their abs and, of course, by cold pressing. I will say right away that it is incredibly difficult to find such a person, only a few succeed.

You'll just have to sweat. Why? Because many have an oil press, and squeeze out the product correctly and observing ancient technology only a few can. If a person sells a product that he himself does not use, he is disingenuous.

Option number 3

A good easy way is to buy oil in specialized stores. Nowadays there are good producers, who do it conscientiously and are guided by people leading a healthy lifestyle and raw foodists.

They usually sell their products via the Internet, because they know that only here they will have buyers who appreciate the quality of the goods. I know one a good place: here is the link.

Option number 4

Buy a press + flax seeds, and make flax oil yourself at home.

Probably a good option, but why do you need so much oil and cake? In this case, you need to sell products to justify the cost of buying an oil press.

How to store linseed oil?

Keep at home and use linen product food is quite simple. But some people have problems with this. So I'll explain better.

1. Correct use

Cold-pressed product intended for refilling vegetable salads. Under no circumstances should it be heated. It is also undesirable to carry out any manipulations on it, such as emulsions in raw food dishes.

Council number 1. Flaxseed oil should not be treated purely as a dietary supplement, weight loss product or medicine. This complete product nutrition!

Council number 2. Do not abuse! Use it with such an interval: three months the product in the diet, then a month or two breaks.

2. Where to store the product?

It's simple here. In a dark place, away from heat sources and any electrical appliances. If the oil is sold in a cardboard box, then it should be stored in it.

It is advisable to store the product in the refrigerator, but not at very low temperatures. If you use the product within a week, you can store the bottle without a refrigerator.

3. Storage after opening

How much to store? After opening the bottle, it is advisable to use the oil within 1 month. Guys, it goes rancid and is not stored for a long time after opening. What do you think it says? That's right, about its quality.

Friends, at the end of the article, I have prepared for you a short video about linseed oil, where I clearly show what to look for when choosing and storing it.
