Expiration date of baking soda: how to store an open pack

Soda is such a familiar substance in our everyday life that we don’t think about the importance of this chemical compound. Meanwhile, sodium bicarbonate is a substance of strategic importance. The scope of application of sodium bicarbonate is enormous. That is why one of the largest Russian ones is classified as an enterprise of paramount importance.

It is difficult to describe in brief how important soda is not only for the economy of a particular country, but also for civilization as a whole. It is even more difficult to name a chemical compound that has equally global significance for completely different areas of activity:

chemical industry - production of foam plastic, dyes, household chemicals;
light industry - production of sole rubber, artificial leather, finishing of cotton and silk fabrics;
food industry, culinary - bread baking, confectionery production;
medicine - therapy of various pathologies through oral, infusion and inhalation administration;
fire extinguishing - filler for fire protection systems;
transport - neutralization of electrolyte in batteries.

In everyday life, BSK products are equally widely used. Housewives use baking soda to clean countertops, dishes and cutlery from dirt, as well as to prepare homemade baked goods, remove stains and about a dozen other household chores.

How to choose

On sale, baking soda can be found in hermetically sealed plastic bags and cardboard boxes, which do not always reliably protect the bulk product. To check the quality of such packaging, it is turned over and shaken quite vigorously. If the white substance spills out, most likely the box is not sealed and the product has absorbed moisture in the air. Such products lose their quality, so it is better to take another package.

Like any product, baking soda has a limited shelf life. It is indicated by the manufacturer in the same way as the release date of the product.

What to look for when purchasing

Baking soda is available in various packaging - cardboard boxes, plastic jars with a screw-on lid, and plastic films. Like other products, it has an expiration date, which is indicated on the packaging along with the date of manufacture.

The most easily depressurized material is cardboard. If you buy the composition in a cardboard package, check it for integrity. To do this, you need to turn the box upside down and shake it slightly. If soda dust appears, perhaps the substance has already begun to absorb moisture from the air and gradually lose its properties.

For your information. Baking soda is also called bicarbonate, sodium bicarbonate E500 (ii) and sodium bicarbonate. The chemical formula of the product is NaHCO₃.

Conditions and shelf life

This substance is capable of maintaining quality for a long time under certain conditions. Baking soda should be stored:

in a place protected from sunlight;
at low temperatures;
and low humidity levels.

To ensure that the substance does not lose its original properties, it must be kept in a closed container. If moisture still gets into the product, the spoiled part is thrown away, leaving only the dry part.

What you store the soda in doesn't really matter. It is important that it is a dry container (preferably, of course, glass, metal or ceramic) with a tight-fitting lid.

At room temperature and in a tightly closed container, the guaranteed shelf life of baking soda is 18 months.

BSK - the soda giant of Russia

Construction of the future largest soda plant in Russia began in 1941. This proves the extreme importance of the facility - one of the few civilian enterprises that were built during the Great Patriotic War. In 1945, the construction of buildings, installation and commissioning of equipment were completed. The plant produced the first batch of caustic soda, which the Soviet Union urgently needed. The company began producing food-grade (purified) sodium bicarbonate only in the 60s. Since then, it has taken a leading position in quality and production volume, which it maintains to this day.

In 1994, the history of the joint stock company BSK began - a modern enterprise, in the form in which we know it today. Modernization of equipment, introduction of innovative technologies, establishment of partnerships - all this allowed the plant to maintain and strengthen its position in the market. The brand's products have received more than 100 different awards, including the All-Russian Brand (III Millennium). Quality mark of the 21st century." The plant is a strategic partner of the military-industrial complex, meeting the needs of industry, as well as ordinary citizens.

Storage in open packaging

You cannot store soda in an open bag (box). It will begin to absorb moisture and surrounding odors, as a result of which it will quickly lose quality. The bulk product must be immediately transferred to a container with a lid and placed in a dark, dry place. You need to put a sticker on the jar indicating the release date of the product and its shelf life. This is done to know exactly when it will need to be replaced with a fresh one.

Baking soda can be stored in unsealed packaging for no longer than 6 months, after which the product is checked for compliance with quality. To do this, pour a little substance onto a saucer and pour a small amount of vinegar or citric acid solution onto it. If a reaction occurs in which carbon dioxide is released, and the soda hisses, it is still quite suitable for use.

How to check the properties of soda

The first thing you can do is smell the substance. If it has absorbed foreign odors, it will immediately become noticeable. You can also scoop up some of the powder with a dry, clean spoon to examine the structure for lumps. They indicate the presence of moisture in the composition.

A simple quality test using the quenching method:

pour 1 tsp into the container. soda;
add the same amount of vinegar or lemon juice (can be replaced with citric acid diluted in a small amount of water);
We observe the test result.

If the product is suitable for use, a violent reaction will occur in the form of hissing and active foam formation. If such manifestations are weak, then it is not recommended for use in culinary products. In this case, the test shows that the product has already lost its properties and will not be able to loosen the dough.

Using an expired product

After 6 months from the moment the package is opened, it is undesirable to use soda for culinary and medicinal purposes. But you shouldn’t rush to throw it away. This powder can be useful, for example, for cleaning silverware. And you can store it as long as you like, the main thing is to keep it in a closed container to protect it from moisture.

There is nothing complicated about how to store baking soda. Read our recommendations carefully, and you will always have a quality product at hand, suitable for all occasions.

How much is it and what does it depend on?

Any packaging indicates that the shelf life is unlimited, provided that the product is properly stored. The determining factor in this case is the date of manufacture.

Requirements for soda are determined by the rules of GOST 2156-76, 32802-2014 and SanPiN 2.3.2.1324-03.

How long can it last after opening the package?

Each package indicates the shelf life of the product - 12 months. When opened, this period is reduced to six months. This is due to the fact that the seal of the packaging is broken.

What to do with leftovers

After six months have passed since the package was opened, it is not advisable to use soda for cooking. But she is not at all spoiled. Therefore, feel free to pour it into another package. Now this powder is suitable for adding shine to silverware. In this case, the shelf life is practically unlimited. Make sure that no moisture gets into it. Then it will retain all its beneficial properties for a long time.

Even after several years, baking soda will perform its tasks just as well as the first day you opened the package. Standard packages of 0.5 kg are available for sale. You can use a little for table use and use the rest at home. Then you will have time to use up the package in 6 months and buy a new one when this period comes to an end. Experienced housewives recommend replacing modern cleaning products that contain harmful acids and caustic alkalis.

Can I use it if the specified time has expired?

After the expiration date, the product can be used, since such a period is practically unlimited, for example, for washing dishes and other surfaces. But when more than six months have passed since opening the package, it is better not to use it as a dietary supplement.

If there is such a need, then you should make sure that there are no signs of spoilage of the product . Confirmation is a reaction to water or vinegar. If when these substances come into contact, hissing begins or bubbles form, the product can be used. Otherwise, it is better not to use it.

The expiration date is not limited by law. The only condition for ensuring this property is proper storage. If after a while doubts arise about its suitability, you can check its quality at home.

Soda production

Many centuries ago, humanity discovered soda, but for a long time this food additive was an extremely expensive product. Not everyone had the opportunity to extract it from soda lakes and mineral deposits, of which there were very few to meet the needs of society.

In the 18th century, the French Academy of Sciences announced a competition to create technology for the industrial production of soda.

Sixteen years later, chemist Nicholas Loblanc proposed a method for synthesizing a product from heated sodium chloride (NaCl, known as table salt), which was then heated with natural lime and charcoal. However, in the second half of the nineteenth century, the Belgian engineer Erest Solvay created a more innovative method. A highly concentrated sodium chloride solution is saturated with ammonia and carbon dioxide. This produces ammonium chloride (NH4HCO3), which is then forced to react with table salt again. The result is ammonium chloride (Na4Cl), which quickly dissolves in water, as well as a precipitate of sodium bicarbonate (NaHCO3), known to people as soda.

The Solvay soda production method is the fastest and most cost-effective, so it is successfully used by industrial enterprises and scientific laboratories. In the Russian Federation, the main percentage of baking soda produced is in the city of Sterlitamak, located in the Republic of Bashkortostan, Volga region. OJSC Bashkir Soda Company has been producing table sodium bicarbonate since 1967.

Cloths for dishes and tables

They are handed over to the catering department for boiling at the end of the day, dried and stored dry in a container marked “clean rags”.

Appropriate markings must be present on sinks, (10 l) sanitary equipment and on containers with cleaning agents and detergents.

Storage of working solutions:

Soap-soda and disinfectant solutions are stored in dark containers with tightly closed lids. The shelf life of a soap-soda solution is 5 days, a disinfectant solution is 3 days.

general description

This additive is officially called E 500. It is in every housewife’s kitchen. And where would we be without her? We add it to baked goods and use it as a cleaning agent. And salt, soda and iodine are a great way to cure a sore throat. It can be used as a detergent that compares favorably with what is sold in stores. Does baking soda have an expiration date? Housewives sometimes think about this when the box has been sitting on the shelf for a very long time. Today we will deal with this issue.

What are the benefits of water and soda on an empty stomach?

General benefit

The sodium and selenium contained in baking soda are essential for the proper functioning of the body. Drinking soda on an empty stomach can reduce the acidic environment in the digestive tract, which has a beneficial effect on overall health, prevents the development of stomach and duodenal ulcers, slows down the aging process and improves dental health.

Water mixed with sodium bicarbonate acquires hydrogen ions, due to which its consumption thins the blood, removes toxins, improves the absorption of nutrients from food, and also promotes faster and better formation of protein structures.

Properties, daily doses of microelements and symptoms of their deficiency

The sodium microelement improves the water-salt balance in the body, has a beneficial effect on the digestion and absorption of food, maintains the correct acid-base balance in the gastrointestinal tract and the function of nervous and muscle tissue, activates enzymes of the pancreas and salivary glands, and has a vasodilating effect.

The average person needs 550 mg of sodium per day; for children and adolescents, the daily requirement can be increased to 1300 mg. Pregnant women should get at least 600 mg of sodium per day. It is best absorbed together with vitamin D. Sodium deficiency is expressed in the following symptoms:

memory impairment;
loss of appetite;
chronic fatigue and muscle weakness;
muscle spasms (for example, spasms during sleep);
vomiting, which leads to dehydration;
skin rash.

Selenium, although in smaller doses, is also necessary for every person. This natural trace element has the ability to improve immunity and stimulate metabolism and the endocrine system, and is also involved in the formation of red blood cells. In addition, selenium has a scientifically proven ability to reduce both benign and malignant tumors.

The daily dose of microelements is 110-140 mg for an adult, 80 mg for a teenager and 20 mg for a newborn. A pregnant woman should get at least 400 mg of selenium per day. Signs of selenium deficiency in the body:

chronic muscle fatigue and weakness;
decreased immunity;
anemia;
deterioration of the kidneys and pancreas;
reproductive dysfunction.

For each group, it is preferable to drink water and soda on an empty stomach. This drink is also useful to drink during weight loss and breastfeeding.

For women

The duet of water and soda has a beneficial effect on a woman’s beauty, improving the condition of her skin, teeth, hair and nails. The high sodium content of this mixture can normalize the menstrual cycle and prepare a woman for successful conception. In addition, rinsing with water and aqueous soda solution will help solve the problem of thrush, because this is a proven folk remedy for this disease.

For men

Selenium deficiency can result in male infertility because the quality of seminal fluid will not be adequate to reproduce new life in a female egg. Therefore, for the strong half of humanity, drinking water with soda on an empty stomach is important both for prevention and for planning offspring. In addition, soda has a beneficial effect on potency, which allows a person not to lose his grip in bed until old age.

During pregnancy

The use of water and soda during pregnancy in case of thrush due to hormonal changes, since the use of many pharmaceutical products is contraindicated for the expectant mother.

This product is also an excellent assistant in maintaining teeth and eliminating heartburn in a pregnant woman, but to be safe, it is better to avoid soda in the 2nd and 3rd trimesters. In addition, there is a popular method for determining pregnancy: 1 tablespoon of soda is added to 100 ml of urine. It is believed that if the powder does not react with urine, but precipitates, the woman is pregnant. However, the result should always be double checked with a routine pharmaceutical test.

When breastfeeding

When breastfeeding, soda should be consumed with caution and preferably not on an empty stomach (3 hours after meals and half an hour before the next meal) to avoid excessive saturation of mother's milk with excess sodium and selenium. However, it is better for nursing mothers to take water with soda against inflammation and thrush than medications that would contraindicate breastfeeding.

It should also be remembered that pregnant and breastfeeding women need large amounts of selenium and sodium (400 mg and 600 mg daily). In the case of HB, there is no need to abuse soda, and in the best case, completely eliminate it, get nutrients from natural foods.

For children

A growing body really needs nutrients that will support the creation of healthy muscle tissue. Moderate consumption of baking soda for children can be used both to meet daily sodium and selenium requirements and to safely treat sore throats and coughs.

When losing weight

Soda drink is a proven folk remedy for weight loss. When it enters the body, baking soda breaks down into sodium, selenium and carbon dioxide. The latter is able to speed up metabolic processes, which will help the part of the body with an additional layer of fat while maintaining a calorie diet (up to 1200 kcal per day for women and 1500 for men) and regular exercise.

Definition of quality

When interacting with the bite, fresh soda begins to actively foam. If the reaction is weak, the product is not the freshest. But even such a substance can be used for household purposes. For example, it can be poured into the bottom of a trash can, which will help remove unpleasant odors. In addition, soda will prevent the proliferation of harmful microorganisms, which develop very quickly, especially in the summer heat.

Harm of soda and contraindications:

Baking soda also has contraindications and in some cases can harm the human body. Baking soda can be harmful if it comes into contact with human skin for a long time. Baking soda can cause even more serious harm if the baking soda powder comes into direct contact with the mucous membranes of the human body - you can get burns. Dry soda is a strong alkali. Also, severe harm to the human body can be caused by ingesting a concentrated solution of soda.

Be careful when using soda, follow the proportions strictly according to the recipe. An overdose of soda can cause serious harm to the human body. Since baking soda can be dangerous to humans, it is recommended to keep it away from children.

Baking soda is an acidic salt of carbonic acid and sodium, which is a fine white powder. The chemical name for baking soda is sodium bicarbonate, sodium bicarbonate, or sodium bicarbonate. For culinary purposes, baking soda is sold under the brand name "Baking Soda". Baking soda is used in cooking mainly as a baking powder, both as part of ready-made mixtures and separately. But when using natural baking soda in its pure form, if the proportions and preparation order are not followed, it can leave a specific taste in the dish. When used correctly, baking soda makes the dough fluffy and soft, pleasant to the taste and touch.

Chemical formula

For chemists, this powder is represented by the following letter images - NaHCO3. The taste is salty and soapy. But if you add it to a solution of acetic acid, a neutralization reaction will occur. The result is a fizzy drink. To prepare it, you need to monitor the expiration date of baking soda. Then the result will be guaranteed to be expected.

The composition of soda is always the same. It is strictly regulated by quality standards, determined by category and grade. It is this technical documentation that contains information about the permissible levels of sodium carbonate, which causes the alkaline reaction, as well as other impurities.

Quite often, soda is used in pharmacology to prepare various drugs. In this case, the chemical purity of the substance is especially important. Therefore, there is a separate regulation for it, which regulates the composition, as well as the shelf life of baking soda after opening.

How to prepare a soap-soda solution for disinfecting premises

Nowadays, stores offer a huge selection of detergents and disinfectants. Many of them contain chlorine, which negatively affects health. It is possible to treat rooms with chlorine only in the absence of people. But even after such treatment, chlorine vapor remains in the air and enters the respiratory tract.

This is especially dangerous for children and people with allergies.

Soap and soda solution for disinfection is safe for health. It is recommended to be used for cleaning premises in children's institutions, hospitals and kindergartens. Toys and other common items are treated with soap and soda solution. This is especially important during epidemic periods.

At home, you can also wash floors, toys, and furniture with a soap-soda solution, especially if one of the family members is sick with a viral infectious disease.

An important quality of a homemade soap-soda solution is its low price. This is perhaps the cheapest disinfectant available in every home.

Depending on the degree of contamination of the room, prepare a one- or two-percent soap-soda solution.

To prepare a one percent soap-soda solution you will need:

10 liters of water;
100 g laundry soap;
100 g soda.

To prepare a two percent solution of soap and soda, take twice as much for the same amount of water. Instead of regular soda, you can use soda ash to wash floors. Premises in kindergartens are cleaned at least once a day. Treatment of floors at home should be carried out after contact with a sick person or once a day during epidemics. The following soap and soda solution is recommended for treating children's toys:

50 g soap;
2 tbsp. spoons of baking soda;
1 liter of warm water.

After treatment, the toys are rinsed in a weak solution of baking soda and wiped dry. Shared toys are washed every day. It is recommended to treat toys at home with soap and soda solution during epidemics and after contact with sick people.

There is a recommendation on what to do if a mercury thermometer breaks. First, the mercury is collected with a syringe or a rubber bulb for douching. The container of mercury is then sealed in an airtight container and services are called to dispose of the mercury.

The floor is treated with a soap and soda solution of the following composition:

60 g soap;
60 g soda ash;
2 liters of water.
