How to store flaxseed oil

Flaxseed oil differs from other vegetable oils in a large amount of fatty acids, which quickly thicken when in contact with air. At the same time, polymerization occurs, the surface of the oil dries quickly and becomes covered with a thin, durable film.

In what container to store flaxseed oil

• To prevent the oil from drying out, it is stored in a well-closed container. Hermetically sealed bottles with a narrow neck are best suited for this purpose.
• Oil containers should be made of opaque glass so that the sun's rays do not start the oxidation process, in which the oil will turn rancid.

• Some housewives put butter in the refrigerator. But in this case, it will thicken and it will be difficult to get it out of the bottle.To return the oil to its previous appearance, it must be left at room temperature for a while.

How to store flaxseed oil properly

Storage temperature

Store linseed oil at a temperature of 20-23 ° C. This condition allows you to keep omega-3 and omega-6 fatty acids in the oil for a long time.

Flaxseed oil, like, in fact, other vegetable oils, retain their beneficial properties only when properly stored. However, unlike other oils such as olive or sunflower oil, flaxseed oil is considered more vulnerable and susceptible to environmental conditions, and therefore deteriorates much faster.

The oil is extracted from flaxseed by cold pressing. High temperatures are not used in the mining process. Therefore, when storing oil, you must adhere to the same principles. For proper storage of flaxseed oil, a certain temperature regime should be used.

Always store oil in sturdy glass containers. The packaging material must not react with the components of the oil itself. Glass bottles of green or brown color with a narrow neck, which should be closed with a tight stopper, are best suited for storage. By the way, ceramic containers are also suitable for storing oil, but only if they are additionally processed inside. It is convenient to store oil bought in bulk in such a container. And never buy too much oil - you will not have time to use it up, and after a certain period of storage, the oil will lose most of its beneficial properties.

Store linseed oil in a dark place, away from direct sunlight. Ultraviolet light triggers the oxidation of polyunsaturated fatty acids, due to which the product quickly loses its usefulness. Therefore, put the oil in a cabinet with blind doors.

For proper storage of linseed oil, use a container with a tight stopper or lid. The fact is that the oil is oxidized by oxygen. If the lid is loose, the oil will dry out and be covered with a film. With prolonged contact with air, free radicals will begin to form in its composition, thanks to which linseed oil will quickly turn into the category of harmful products.

The shelf life of flaxseed oil in a sealed package is 1 year, but after opening the oil should be consumed within a month.

How to store butter

Temperature conditions and storage locations

The optimal temperature regime for storing butter for daily use is from 0 to 6 degrees. This is the climate that a refrigerator can provide; here the oil can be stored for 15 days after opening.

To prevent butter from being too hard and easy to spread on bread, it should be stored on the top shelf of the refrigerator, in the fruit and vegetable compartment, or on the door shelf.

But for long-term storage (up to 1 year), you need to use a freezer. But still, this option is not the best, since with a long cold storage butter becomes less tasty and healthy.

Remember not to leave butter at room temperature for a long time. Due to exposure to heat and light, it will turn yellow, oxidize, and lose its beneficial properties and taste.

However, if there is no refrigerator nearby, for example, in field conditions or in a country house, then you can save the oil in one of the following ways:

Method 1. Wrap the oil in a cotton cloth soaked in a solution of water and vinegar. When the cloth is dry, soak it again in the solution.

Method 2. Put a piece of oil in a jar and pour vinegar so that it covers the block by a couple of centimeters.

Method 3. Wrap a bar of butter up to 200 g (or several bars) in parchment, then place it in a deep container and fill it with a strong salt solution. Store the container of oil in a dark place and change the saline solution daily.

What to store

You can store butter both in an oiler and in factory-made foil packaging. Parchment paper (pictured below) or foil will also work. The main thing is that the packaging or container should protect the oil from light.

You should not store butter in plastic containers and plastic bags - in such a container, the product will quickly turn rancid, turn yellow and deteriorate.
