Vinegar essence

Vinegar essence- the name of an 80% aqueous solution of acetic acid obtained in industry by pyrolysis of wood or from mineral hydrocarbons. In principle, vinegar essence can also be obtained from vinegar produced by acetic acid fermentation of alcohol-containing liquids, but this is economically unprofitable, therefore, in modern conditions, all vinegar essence is produced from purified acetic acid produced from non-food raw materials.

Application

Acetic essence, and more often food acetic acid (70% strength), is used for the preparation of marinades, canned food, etc. (see Canning), as well as table vinegar.

Toxicity

Poisoning with vinegar essence or food acetic acid is one of the most common household intoxications, usually they are the result of suicide attempts, less often they occur when the essence is accidentally taken. A dose of 30-50 ml of food grade acetic acid can be fatal in the absence of immediate help.

Signs of poisoning

Severe burns of the mucous membrane of the oral cavity, pharynx, esophagus and stomach; the consequences of the absorption of vinegar essence - acidosis, hemolysis, hemoglobinuria, impaired blood clotting, accompanied by severe gastrointestinal bleeding. Significant thickening of the blood is characteristic due to the loss of plasma through the burnt mucous membrane, which can cause shock. Dangerous complications of vinegar essence poisoning include acute renal failure and toxic liver dystrophy.

First aid

Drinking plenty of fluids Inducing vomiting is extremely dangerous, as the secondary passage of acid through the esophagus will aggravate the burn. Shows gastric lavage through a tube. Immediate hospitalization is required.

Description

Acetic acid in a concentration of almost 100% is called glacial, an aqueous solution of this acid (70-80%) is called acetic essence, and a highly acidic liquid with a concentration of 3-15% is a well-known ordinary vinegar. It should be noted that acetic acid in various concentrations is actively used in industry, in particular in food (E260), as well as for home cooking, for example, for canning.

If we follow the official data, then an 80% aqueous solution of food-grade acetic acid, which is obtained industrially during the fermentation of acetic acid alcohol-containing liquids, is commonly called acetic essence. As a rule, vinegar essence is further used to obtain less concentrated table vinegar, as well as for the preparation of marinades and canning.

Very often, according to one or another recipe, the usual 9% vinegar is required, and only essence is available, or vice versa. This turn of the matter puzzles many housewives, but in reality, both of these products are interchangeable. And the main thing that you need is to know the exact proportions.

For example, to get ordinary table vinegar from the essence of 70%, you need to take 1 tablespoon of the essence

• - for 3% vinegar - 20 tbsp. water;
• - for 6% - 11 tbsp. water;
• - for 9% - 7 tbsp. water.

For the reverse process, you will have to reduce the amount of water, but take more ordinary table vinegar. That is, to get 1 tablespoon of vinegar essence at a concentration of 70%, you need to take:

• - 7 tbsp. water - 8 tbsp. 9% vinegar;
• - 11 tbsp. water - 12 tbsp. 6%;
• - for 20 tbsp. water - 21 tbsp. 3%.

Acetic acid preparations

Glacial acetic acid - Acetum aceticum glaciale - contains 96% CH3COOH, used as a cauterizing agent for calluses and warts.

Acetic essence, diluted acetic acid (30-80%) - Acidum aceticum dilutum - is used as an itching and keratolytic agent in various ointments. 30% vinegar essence, along with formalin, is used for fungal diseases and mycosis of the feet as a means for disinfecting shoes, treating insoles in order to prevent self-infection: the inner surface and insoles of shoes are wiped with 30% vinegar essence applied to a cotton swab and placed in a tightly tied plastic bag on 2 hours, after which the shoes are ventilated until the smell disappears.

Table vinegar (9%) - Acetum - diluted (2–5 tablespoons per glass of water) is used as a soothing agent for itching, urticaria, insect bites.

Undiluted vinegar is used for head lice to remove head lice nits. In folk medicine, a decoction of calamus rhizomes used to treat baldness and hair loss, a decoction of nettle leaves, used to treat seborrheic alopecia, is prepared on vinegar.

Table vinegar mixed with boric acid and cologne or alcohol (boric lotion) is used for excessive sweating (hyperhidrosis).

Fragrant vinegar - Acetum aromaticum - greens of tarragon, celery or dill (50 g) per 0.5 l of 9% table vinegar, you can also add black currant leaf and lime blossom (50 g). Insist for 2 weeks, filter, and store in a tightly sealed dark glass bottle. Fragrant vinegar is used for rubbing the skin, tightens the enlarged pores of the face, has an astringent and refreshing effect, and is used for hyperhidrosis (sweating).

Apple cider vinegar is used as a disinfectant and soothing agent for daily rubbing of the affected skin with pyoderma (impetigo).

Acetic acid poisoning

Acetic acid acts more superficially than inorganic acids. Otherwise, its action in case of poisoning is similar to the action of inorganic acids (nitric, sulfuric, hydrochloric).

Acetic acid vapors, when poisoned, enter the lungs and are released by them, which leads to severe pneumonia.

Characterized by hemolysis and associated hemoglobinuria.

A lethal dose is 12-15 ml of anhydrous acid or 20-40 ml of vinegar essence (200-300 ml of vinegar).

Acetic acid is easily identified at autopsy by its specific odor; also characterized by necrosis, hemorrhages in the liver, hemolysis, necrotic nephrosis, etc.

Properties

Acetic acid (CH3COOH, acidum aceticum) is a natural limiting monocarboxylic organic acid, it is a colorless transparent liquid with a specific odor.

Acetic acid is the starting material for the biosynthesis of fatty acids, steroids, sterols, and terpenes in the body. Participates in the formation of acetyl coenzyme A.

The benefits of vinegar essence

Vinegar essence cannot be considered a useful product, but without it it is impossible to carry out some culinary processes. In moderate quantities, vinegar essence has a stimulating effect on metabolic processes in the body. Vinegar helps the body fight various infections, removes putrefactive formations from the body.

How to work with essence

Safety rules are simple:

• Keep essence out of the reach of children and pets.
• The container must always be signed.
• In no case should you eat undiluted essence - it is deadly.
• Acetic acid causes severe burns to the mucous membranes, so you need to work with it very carefully, avoiding contact with the skin and eyes.
• In case of contact with skin, rinse with plenty of running water, then with a weak solution of baking soda.
• In case of contact with eyes, rinse with plenty of running water and seek medical advice immediately.

Harm and contraindications

By itself, vinegar essence is a toxic inedible substance used in everyday life. It is this liquid that often becomes the cause of intoxication and serious poisoning. Indeed, in the absence of timely assistance, only 30-50 ml of 80% vinegar essence can become a lethal dose.

If by chance the vinegar essence gets inside the body, it can lead to severe burns of the mucous membrane of the mouth, pharynx, esophagus or stomach. In addition, even a single intake of this liquid can lead to diseases such as hemolysis, hemoglobinuria, acidosis, as well as bleeding disorders, which is accompanied by severe bleeding in the gastrointestinal tract. To avoid these unpleasant consequences, it is necessary to apply the essence of vinegar and any other only in diluted form and in small quantities, and also store it as far away from children as possible.

Some ordinary people believe that there is no difference between vinegar and the acid of the same name. But this opinion is wrong, and the two products cannot be called interchangeable. Consider what features are present in each case and how vinegar differs from acetic acid.

Acetic acid is a corrosive substance with the formula CH 3 COOH.

Comparison

In each case, the object of attention is a colorless, sometimes slightly colored liquid of natural or synthetic origin. And the difference between vinegar and acetic acid lies in the content of the main substance.

The basic component is acetic acid. It can be absolute, waterless. You will not find such a product on free sale. It is intended for laboratory use only. The acid is handled with extreme caution, since even its vapors are highly irritating to the mucous membrane of the respiratory tract. And ingestion of a very small dose can cause fatal burns.

However, there is a product in this category on the shelves, which is an acid diluted 20-30% with water. It is called "vinegar essence". The concentration of the main substance in such a solution is also very high, therefore, one must be careful here too. The essence is most often purchased in order to further add water to it in the right amount and get nothing more than vinegar. This final composition has a less sour taste.

So, vinegar is the solution with the smallest concentration of the base substance. It can be as high as 15%. But the most widely used composition is in which the proportion of food acid is much less - 9 or 6%. An already finished product can be bought without any problems in a regular store.

Considering what is the difference between vinegar and acetic acid, it is worth mentioning the benefits of products of this category. The acidic composition is in demand as an important ingredient in everyday cooking and for preservation. But vinegar is used not only for food purposes.

With it, for example, you can remove rust and scale from objects, as well as remove blockages, using soda and boiling water in addition. The vinegar added to the flower vase prolongs the life of the bouquet. This composition will remove the stale smell from the refrigerator or cabinet, it is only necessary to wipe the surface with a damp cloth. Vinegar finds its use in many other ways.
