Can you use expired sunflower oil on your farm and how?

Any vegetable oil that is rancid or expired should absolutely not be eaten in any form.

As soon as you smell rancid oil, or an unusual bitterness appears in its taste, then, even if the expiration date has not yet completely expired, such oil should absolutely not be eaten.

Premature spoilage of oil can occur due to violation of storage conditions.

But you shouldn’t throw away sunflower oil that has gone rancid or spoiled. It will find use on the farm.

It can be used as a thinner for oil paints when you wash your hands or tools that you have worked with.

Also, from any missing vegetable oil, you can make liquid or solid soap for use for household purposes: for washing dishes, when added to water for washing floors, for washing.

What you can eat without risk to your health, even if the expiration date has expired

Cookies, bread, rolls, biscuits Baked goods, if they do not contain cream, can be stored almost indefinitely. The main danger is mold. If you find it on bread, it is better not to try to cut off the damaged area - the spores have spread throughout the product, and the consequences of such an additive may be fatal to the body. Moreover, we separately note that this mold is not penicillin at all and does not bring any benefit to the body.

Danger. Mold is the main source of danger in such products. It can provoke both allergies and serious toxic poisoning.

How to store. The easiest way to extend the life of bread is to store it in the refrigerator. The main thing is to ensure that condensation does not accumulate in the bag and mold does not appear. If the bread or biscuit has become stale, a minute in the microwave will restore its former freshness.

By the way, just a note. Our confectioners, by putting an expiration date on cakes, protect themselves - after the date, the dessert can be consumed for at least two days without much fear. But store only in the refrigerator. And if there is any strange taste, throw it away.

Milk and fermented milk products

As a rule, even despite the expiration date, milk and other fermented milk products are quite suitable for consumption for at least a few more days.

Danger. If milk tastes bitter, this indicates that it is spoiled - you cannot drink it in its “raw” form, you can be seriously poisoned. The fact is that various microbes multiply in milk at an accelerated pace, including E. coli and staphylococci, which can cause toxic infection and dysbacteriosis.

How to store. Scientists note that pasteurized milk can be stored 50% longer if it is kept at low temperatures. Therefore, only the refrigerator and darkness. If milk (sour cream, cream, cottage cheese, kefir) has expired, you can use it to prepare a lot of dishes - from pancakes to cheesecakes. The main thing is to make sure that there is no mold on these products.

Oil

Whether it’s creamy or vegetable, even after the expiration date, they completely retain their taste. The main thing is to store it correctly.

Danger. All fats over time (especially in light) undergo oxidation with the formation of toxic compounds. When butter oxidizes, it becomes covered with a yellow coating and acquires a rancid taste. The changes that occur in expired vegetable oil are not so noticeable, but this does not make them any less dangerous for humans. Atherosclerosis is one of the cute diseases that await you. If the oil develops a characteristic rancid aroma and taste, it can no longer be eaten.

How to store. If you buy butter in bulk at discounts, the most convenient and correct thing to do is store your treasure in the freezer. The oil can be stored in this way for months. You can’t put vegetable oil in the freezer; it is most comfortable in the darkness and coolness of a regular refrigerator - for a period of 4 months.

Eggs

Another product that can easily be stored in the refrigerator for at least a month, or even more. Provided that everything is in order with the shell and storage conditions too.

Danger. The fact that the eggs have spoiled becomes clear immediately - by the unbearable aroma. In addition, it happens that the egg is infected with salmonella - it does not manifest itself in any way. Therefore, before eating, eggs should still be heat-treated, and to prepare cream for tiramisu (a popular Italian dessert), it is better to choose the freshest eggs from “proven” chickens.

How to store. Eggs should be kept at a temperature below +5 degrees, as this prevents the potential growth of salmonella bacteria. On average from three weeks to a month. Well, the freshness of the egg is checked with water - an old or spoiled egg will float. The fresh ones will remain at the bottom of the bowl.

Pasta, cereals and flour

From the series of forever preserved. Nothing happens to them, except that some bugs may appear if five years have passed. Well, jokes aside, cereals and pasta are among the longest shelf-stable foods.

Danger. If stored correctly, it can be consumed years after the sell-by date. If you find mold or bugs, throw everything away without regret.

How to store. In sealed packages, in a dry place. Do not allow moisture to enter - otherwise they will sprout and spike.

Canned food

If stored correctly (and before that, if properly manufactured), canned food can last for years. True, not everyone takes the risk of trying them, but Estonian scientists note that the results of microbiological studies prove the safety of eating them, even if the “better before” period has passed. Separately, it is worth paying attention to home preparations - if the technology is not followed, the consequences can be very different.

Danger. Expired canned meat, fish, and especially vegetables and mushrooms can cause botulism, a deadly human disease. Of course, it is quite difficult to be poisoned by store-bought stew, even if it has already outlived its useful life, but homemade mushrooms and hodgepodge may well become a haven for clostridia that produce botulinum toxin, which affects the nervous system and leads to respiratory arrest.

How to store. Placing canned food in a cool, dark place can significantly increase its shelf life. This applies to almost all factory products, jams and honey.

Fresh salad in packages

As long as this vegetable is not affected by mold, it is safe to use. Simply rinse the salad with cold water.

Dangers. As with most foods, the main danger is mold and rot. If you notice similar manifestations on the leaves, say goodbye to the entire package without regret.

How to store. In the “green” zone of the refrigerator - not in the coldest place, but not in the warmest place either.

Chocolate

Chocolate is also a product with a long shelf life. And even if it is covered with a white coating, there is nothing wrong with that - this is due to the fact that the fat melts and settles outside.

Danger. Sometimes chocolate moth larvae infest stale sweets. In themselves they are harmless, but who cares?

How to store. Nothing complicated. Not in the refrigerator and not in the heat. The temperature should be slightly below room temperature. And definitely in the packaging.

Vitamins in sediment. Vegetable oil - sunflower, olive, soybean, corn, rapeseed.

Until recently, we simply bought vegetable oil, without specifying its name: besides sunflower, there were practically no other varieties on sale. Now the choice has become much richer. Olive, soybean, corn, and rapeseed oil appeared. What do we know about them?

Vegetable oils are rich in essential polyunsaturated fatty acids - linoleic, linolenic and arachidonic. These acids are part of cell membranes, are responsible for the synthesis of important hormones, reduce cholesterol levels in the blood and perform many other vital functions. They are not formed in the human body, but only come from food, mainly vegetable oil.

Some describe the taste of flaxseed oil as delicately nutty with a noble bitterness, while others find it unpleasantly fishy and downright bitter. As they say, there is no arguing about tastes. But in many ways, the taste of flaxseed oil and its undeniable beneficial properties depend on where, how and how correctly you store it.

Flaxseed oil is even more susceptible to environmental influences than other vegetable oils. Upon contact with air and sunlight, that is, during the process of oxidation and under the influence of ultraviolet radiation, fatty acids polymerize and are destroyed. Structural changes occur in them that transform all usefulness into harm. High humidity and too high or low temperatures (heat treatment and freezing) are also detrimental to oil.

The best way to store flaxseed oil is in a glass bottle, preferably dark in color, with a narrow neck and a tight-fitting lid. The optimal temperature range is from 5 to 25 ℃, the humidity is moderate, in other words, ordinary room conditions are quite suitable.

When purchasing flaxseed oil, be sure to pay attention to the shelf life specified by the manufacturer. As a rule, they are 6-12 months from the date of manufacture. If the oil is packaged in a cardboard box, do not throw it away, but keep the oil directly in it at home, placing it in a dark, cool place, for example, in a kitchen cabinet located away from the radiator and stove, which has blank (opaque) doors.

Unrefined flaxseed oil can also be stored in the refrigerator, but only on the door, otherwise it will thicken. The formation of a small sediment is acceptable; It is considered normal when it does not exceed 1% of the total volume.

After opening the cork, the shelf life of linseed oil is reduced to 2-4 weeks, and so that it does not lose its beneficial properties, the container with oil must be immediately tightly closed after each use.

When opening a bottle of flaxseed oil, write the date on the label to monitor its shelf life. Cloudiness, the appearance of a whitish film or flakes on the surface, and a rancid taste are signs of a spoiled product. This oil will have to be thrown away.

How long is it stored?

Each oil is produced in several ways and has different storage and packaging requirements.

Sunflower

It is produced from the seeds of the annual plant sunflower oilseed. In addition to cooking, cosmetics, and pharmaceutical industries, it is used in the production of paints and varnishes, as well as as a lubricant for various mechanical parts (bearings, bushings). Kinds:

There are different production methods:

1. Cold pressed. Whole sunflower seeds are pressed without preliminary crushing at temperatures up to 40 °C. The final product has an unexpressed taste, light color, very liquid consistency, delicate aroma of seeds, and retains all the beneficial substances as much as possible. To obtain 1 liter, about 6 kg of seeds are required.
2. Hot spin. Pre-crushed seeds with the addition of water are fried at 100…110 °C, after which they are squeezed out, resulting in a product with a more saturated color, taste and aroma, and a viscous consistency. To obtain 1 liter you need 3 kg of raw materials.
3. Extraction. The most economical method, since it allows you to degrease the seeds as much as possible. It is the treatment of crushed raw materials with a solvent, which is subsequently removed. The product is cleaned and deodorized. Most often used in the production of refined varieties.

Sunflower oil is stored for the period established by the manufacturer until the package is opened - from 4-6 months to 1 year. After opening the bottle, it is better to use the refined product within 2 months, unrefined - 5-6 weeks; They are better preserved in glass containers that do not react with the contents.

Olive

It is obtained from the pulp and kernels of European olive fruits: from unripe green ones or ripened ones that are black in color. The product obtained from the former has a sharper taste, while from the latter it is softer, and the yield of the finished product is greater. Used for food, cosmetic purposes, as well as for lighting (in temples, mosques).

Kinds:

1. Unrefined – first pressing:
   extra virgin – high quality, without the use of any filtration methods;
2. virgin - cleaned only mechanically, without any chemical reactions.
3. Refined. Purified through various physical and chemical reactions designed to eliminate the specific strong taste characteristic of the unrefined product.
4. Cake - obtained from pomace by chemical reactions using solvents (hexane), the lowest quality.

The shelf life is set by the manufacturer - usually 1-2 years. Although there are no instructions on the product packaging for how long to store the oil after opening (theoretically, it is allowed until the end of the nominal SG), it is better to use it no longer than 9 months.

The product should be kept in a glass container in the absence of light, in a cool place, preferably on a shelf on the refrigerator door. Storing near a stove or any other heat source will speed up deterioration. Quality olive oil cooled to temperatures below 12°C will form sediment.

Linen

Obtained from flax seeds. Application:

1. Food grade (cold pressed). Widely used in cooking, folk medicine, as a dietary supplement (in capsule form). Heat treatment (in particular, frying) is not recommended due to the formation of carcinogenic compounds under the influence of high temperatures.
2. Technical (hot pressing). Used in the production of paints and varnishes.

The shelf life of the food product is up to 1 year. After opening the package, if it is plastic, it is better to pour it into a darkened glass bottle, close it tightly with a lid to prevent the entry of oxygen, which causes oxidation of the contents, and put it in the refrigerator - the oil will remain there for about 2 months. At room temperature, the shelf life does not exceed 2 weeks, after which it goes rancid.

Coconut

It is made from copra, the dried oily pulp of coconuts, and is widely used in the food, cosmetics and medicine industries.

Obtained by hot or cold pressing. Using the latter method allows you to retain more nutrients, as well as the characteristic sweetish taste and rich aroma of coconut, but only 10-12% of the fat can be extracted. To produce refined oil, the hot pressing method is more often used - the product has a liquid consistency at room temperature (as opposed to unrefined, solid at 20 °C, which begins to melt at 25...27 °C), weakly expressed taste and aroma.

Coconut oil remains suitable for consumption for at least a year from the date of manufacture (six months for unrefined or edible oil). A product packaged in glass, insulated from sunlight, is less susceptible to oxidation or rancidity. Storage for a nominal period of time is allowed outside the refrigerator at 18 °C or inside at 5...6 °C.

Soy

It is made from the seeds of soybeans, an annual plant of the legume family. A source of lecithin, vitamin E, as well as healthy fatty acids (linoleic, oleic, palmitic, stearic).

According to production technology there are:

The product is stored from the date of manufacture until opening for about 1 year at room temperature , relative humidity no more than 85%, without access to sunlight. After opening the bottle, it is better to keep it inside the refrigerator in a glass container and use it within the prescribed period of time, but not more than 6 months.

Rapeseed

It is made from rapeseed seeds, an annual herbaceous plant of the cabbage family. For a long time it was considered only technical due to the unpleasant taste and the content of toxic compounds, but as production technologies improved, these negative properties were eliminated, making the product suitable for food purposes.

According to the degree of purification of the product, the following types are distinguished:

The packaged product is suitable for consumption for about six months (minimum) from the date of manufacture. After opening, it is allowed to store it for the duration of the established SG in a dark, cool place (possibly in the refrigerator), pouring it into a hermetically sealed glass bottle to prevent the development of oxidative processes.

Packing a bag of groceries for a trip to the country is a whole adventure: make a list taking into account the number of people who want to get some fresh air, go to the store, buy half of the list from memory (since, of course, they forgot it at home) and a few more unplanned goodies, because “ I wanted it”... However, there are products that should be at the dacha, regardless of the time of year and the company you are going there with. One of them is sunflower oil! Why? Now we'll tell you! You will be surprised, because many do not even suspect what it can be used for on a country trip.

For culinary masterpieces

One cannot fail to mention the role of this valuable product in cooking. At the dacha, oil is needed not only for salads and frying, but primarily for preparations. It gives snacks a special flavor and allows them to be preserved for a long time. For example, if peeled garlic is poured with sunflower oil, it will be stored in the refrigerator for a long time. You also get a great salad dressing - garlic butter!

Unrefined sunflower oil is the best addition to fresh vegetables from the garden. But it cannot be subjected to heat treatment. Therefore, you can fry only refined ones.

Any vegetable oil has a beneficial effect on our body, strengthens the cardiovascular system, lowers cholesterol levels, improves memory, it is useful for gastritis and peptic ulcers, and has a positive effect on the condition of hair and skin. This is all great! After all, in the summer at the dacha we are trying to strengthen the body and prepare it for the harsh tests of the cold. But it’s not just the nutritional value that makes vegetable oil a must on the garden shopping list. There are situations where it is used for other purposes and thereby replaces a variety of means.

What is the expiration date indicated on a bottle of vegetable oil?

The label of a bottle of vegetable oil indicates the expiration date, that is, the shelf life in a closed container. It is counted from the date of oil spill, which, in turn, must also be applied to the label. The shelf life of most vegetable oils, like all natural products, is relatively short: 12–24 months. Oil can be stored for a longer time only with the addition of artificial antioxidants.

According to GOST R 52465-2005, the minimum guaranteed shelf life for sunflower oil (from the date of manufacture) is:

— for unrefined sunflower oil — 4 months;

— for refined deodorized — 6 months;

— for bulk — 1.5 months.

Therefore, when buying oil, you should definitely pay attention to this. If the label of unrefined oil says “no preservatives,” then it cannot be stored for more than 4 months.

Expired olive oil

Once the container is opened, the shelf life will be shortened to 3-4 weeks. Storing a cold-pressed product Cold-pressed oil is a product of the highest quality. If stored properly in a closed container, its shelf life will reach two years. When the expiration date has expired Once the expiration date has passed, olive oil can be used like regular sunflower oil. The product can also be used for cosmetic purposes. When frying with olive oil, do not use it twice. How to store it correctly? Olive oil will retain its beneficial properties and characteristic pleasant aroma for a long time if stored correctly.

• Do not store olive oil near the stove or microwave.
• It is also worth removing containers with oil away from windows.
• It is important to protect olive oil from exposure to bright light.

Where and how to store

Sunflower oil can retain its properties for a long time if properly stored.
Read on the website: Types of vegetable oils: use in cooking and their properties.
Part 1. For sunflower oil, which is in a closed original package, you should choose a dark place. Under ideal conditions, when storing indoors, the air temperature should be maintained from +4 to +6 ° C and the air humidity should not exceed 75%. Of course, such strict conditions are not needed for normal home storage. The sealed bottle can be stored in a cool, dark place. It is important that the oil is not exposed to sunlight and temperatures above +18 – +20 °C

How else can you use sunflower oil?

From stains on furniture

Did you know that sunflower oil is an excellent stain remover for lacquered furniture? Almost every country house has interior items that migrated here from a city apartment a long time ago. Good quality lacquered chests of drawers, tables or chairs can be easily cleaned using a mixture of oil and alcohol (1:1).

From stains on clothes

Paint stains on clothes are not uncommon in a summer cottage. Often we don’t even try to get them out. But neatness and cleanliness are the best friends of things, even if you only wear them in the garden. There is only one condition: the stain must be fresh. Apply oil to it and wait 5-10 minutes. Afterwards, wash with dishwashing detergent.

From an unpleasant odor

Does the refrigerator at your dacha smell bad after you've been away for a week? Wipe it from the inside with a napkin moistened with sunflower oil. You can also remove the smell of onions from a knife or, for example, from a cutting board.

From insects

If your home is periodically infested by ants, you can protect the food stored there. For example, grease the edges of bags or cans of cereal with sunflower oil. This also applies to picnic products. This simple method will help scare away annoying insects.

Flies are attacking, but you didn't buy adhesive tape? There is a way out! Prepare a special mixture with your own hands:

• melt rosin (90 gr.),
• add sunflower oil (30 g) and 1 teaspoon of honey (or syrup),
• Apply the resulting mixture onto thick paper: the Velcro is ready!

From the creak

The creaking of the front door or cabinet doors is terribly annoying. It is especially unpleasant that it occurs suddenly and at the most inopportune moment. As luck would have it, precisely when the necessary funds are not at hand. This is where sunflower oil comes to the rescue again! Lubricate the hinges with it. However, after some time, still treat them with a special lubricant. The same goes for locks on clothes. Does the “dog” stick on your country bag or jacket? You already know the answer!

For shine

Cutlery should be perfect even in the country! Therefore, regularly treat stainless steel spoons, knives and forks with sunflower oil. Shine guaranteed! The same applies to all kitchen utensils made from this material.

If the lights are turned off

Thunderstorms are far from being the best friends of summer residents. Especially if they are strong and have consequences. One of the most unpleasant things is a power outage. Don't want to sit waiting for the light? Buy an oil lamp! Of course, there are special oils for use in these simple units, but in extreme cases they will be replaced by ordinary sunflower oil. As they say, let there be light!

For beauty

For removing makeup This advice will be of interest only to representatives of the fair half of humanity. If you arrive at the site and forget your makeup remover (and this happens often), use a cotton pad soaked in sunflower oil. It will wash away even stubborn makeup. At the same time, the skin will receive nourishing care (the oil is famous for its content of beneficial acids, waxes, volatile phosphorus-containing substances and vitamins A, D, E, F).

For nails Working in the garden beds is an obligatory part of dacha discipline. However, after it the nails are in a deplorable state. There is a solution: before work, apply sunflower oil to them. It will create a protective film that will prevent dirt from “eating” into the nail plate.

For hair Any woman knows that a bathhouse is a source of health, beauty and youth. Oil will come in handy here too. Write down the recipe for a mask for hair growth and strengthening:

• one yolk (beat)
• + tablespoon brewer's yeast
• + a tablespoon of sunflower oil.

Apply to hair half an hour before the bath. Wash it off last!
