Potassium tartrates e336. General characteristics and obtaining Influence on the body

Food supplement, which is a white crystals. It is highly soluble in water, insoluble in ethanol and fats. Potassium tartrates are prepared by reacting tartaric acid with potassium carbonate or potassium hydroxide.

This substance is formed by potassium tartrate, an average salt of tartaric acid and potassium bitartrates, which are an acidic salt of tartaric acid. The latter are also known as tartar.

Types of potassium tartrates

    Е336i - one-substituted potassium tartrate,

    E336ii - disubstituted potassium tartrate.

Purpose

In the food industry, the E336 additive is used as an acidulant, antioxidant, baking powder, emulsifier, and acidity regulator. It is used in the manufacture of marmalade, soups, jams, jellies, juices, bakery products.

Potassium tartrates are used in galvanic tinning and also in the textile industry for dyeing fabrics.

Impact on the body

Additive E336 exhibits antioxidant properties and renews body cells.

Reduces the flow of venous blood, which is used to relieve the symptoms of hemorrhoids and varicose veins. In addition, it has a diuretic effect, promotes the outflow of bile, and has a mild laxative effect.

Potassium tartrates should be used with caution in children and people who are prone to flatulence and stomach irritation.

Permissions to use

Additive E336 is approved for use in the food industry in all countries, including the Russian Federation.

Potassium tartrate belongs to the group of natural antioxidants, acts as an acidity regulator, stabilizer, acidifier, emulsifier. Potassium tartrate is a white powder, easily soluble in water. Practically insoluble in organic solvents such as fats and ethanol.

Origin and distribution in nature of E-336:

These are potassium tartrate (medium salt of tartaric acid) and potassium bitartrate (acidic salt of tartaric acid). Cream of tartar It is formed by precipitation during the process of making wine. Namely, during the fermentation of alcohols, aging and additional processing. Tartar sediment is formed when wine is shaken or when the temperature drops. Because of this, unbottled wine is kept cool.

Application E-336 in the food industry:

Additive E-336 approved for use in the food industry in most countries, including Ukraine and Russia. E-336 used as a base raw material in the production of tartaric acid. Potassium tartrate is present in instant soups, marmalade, jams, jellies and jelly sweets, juices, concentrates. Also added to flour products and pastries cream of tartar as a disintegrant. Do not do without it and winemakers.

Other applications for E-336:

In addition to food, potassium tartrate is also involved in heavy industry. This natural component is used in the process of galvanic tinning. Also E-336 used for dressing. use cream of tartar and in the dyeing of fabrics and materials as a stabilizer of the coloring composition and a synergist of antioxidants.

Effects on humans of potassium tartrate:

Because the cream of tartar E-336 refers to natural antioxidants, the harm from its use is minimal. The additive affects the venous-vascular system of a person, reduces the flow of venous blood, and therefore, reduces exacerbated conditions with varicose veins, hemorrhoids. Possesses potassium tartrate and diuretic action, regulates the process of outflow of bile, has a mild laxative effect. Not recommended to use cream of tartar E-336 children and people prone to diarrhea, flatulence.

Few would think of drinking fermented grape juice. But a liquid with a sharp sour smell is nothing more than tartrate. The natural substance is an effective antioxidant.

The main name of the additive is potassium tartrates ( GOST is missing).

The international name is Potassium tartrates.

pharmacological properties. Pharmacodynamics. Normalizes the KOS (acid-base state) of the blood, replenishes the deficiency of potassium. It activates many cytoplasmic enzymes, regulates intracellular osmotic pressure, protein synthesis, amino acid transport, conduction of nerve impulses, contraction of skeletal muscles. Potassium ions cause a decrease in heart rate, reduce contractile activity, reduce conductivity, automaticity and excitability of the myocardium. In small doses, they dilate the coronary vessels, in large doses they constrict. Potassium helps to increase the content of acetylcholine and excite the sympathetic department of the central nervous system. It has a moderate diuretic effect. An increase in potassium levels reduces the risk of developing a toxic effect of cardiac glycosides on the heart.

50 mg/ml glucose solution is isotonic to human plasma. It is used as a plasma-substituting liquid.

Pharmacokinetics. The potassium ion is excreted mainly with urine, in a small amount with feces, as well as with saliva, bile and pancreatic juices.

Glucose, entering the tissues, is phosphorylated, turning into glucose-6-phosphate, which is actively involved in many parts of the body's metabolism. Glucose oxidation products are excreted by the lungs (CO 2) and kidneys (H 2 O). Normally, glucose is not eliminated by the kidneys. In pathological conditions such as diabetes mellitus, metabolic disorders with hyperglycemia, glucose is excreted by the kidneys (glucosuria).

Indications for use. Tachycardia, extrasystolic arrhythmia due to hypokalemia, including intoxication with cardiac glycosides.

Method of application and dosage. The dosage regimen and terms of application are set individually under the control of the results of electrocardiography and the level of potassium in the blood serum. As a rule, appoint from 0.5 g to 2 g of potassium chloride per day. The rate of administration is 20-30 drops per minute.

Side effect.

Electrolyte imbalance: hypophosphatemia, hypomagnesemia, hyperkalemia, hyponatremia.

From the digestive system: dyspeptic disorders (nausea, abdominal pain).

From the side of the cardiovascular system: bradycardia, impaired conduction of the heart, arrhythmia, extrasystole, arterial hypotension.

From the immune system: allergic reactions (hyperthermia, skin rash, angioedema, shock).

From the nervous system: in rare cases, when using high doses, weakness, paresthesia, confusion may occur.

General reactions of the body: at the injection site - the development of infection, thrombophlebitis, vein thrombosis, hypervolemia, suffocation, sore throat.

In case of adverse reactions, the administration of the solution should be stopped, the patient's condition should be assessed and assistance should be provided.

Contraindications. Violation of the excretory function of the kidneys, complete heart block, hyperkalemia of various etiologies.

Hypersensitivity, hyperglycemia, hyperlactacidemia, hyperchloremia, hyperhydration, acute dehydration, postoperative disorders of glucose utilization; circulatory disorders threatening swelling of the brain and lungs; cerebral edema, pulmonary edema, acute left ventricular failure, hyperosmolar coma, Addison's disease, intestinal obstruction, significant burns.

With caution: decompensated CHF, diabetes mellitus.

Overdose.

An overdose of potassium chloride for a long time remains asymptomatic until the concentration of potassium in the blood serum reaches a high level (6.5-8 mmol / l). It is manifested by an increase in the manifestations of adverse reactions. Perhaps the development of hyperkalemia and hyperhydration. At the same time, patients experience muscle weakness, abdominal pain, paresthesia, frequent shallow breathing, arrhythmia, loss of consciousness, and fever are possible. On the electrocardiogram, an increase in the amplitude of the T wave, depression of the ST segment, and an expansion of the QRS complex are recorded.

Treatment:

In case of an overdose, symptomatic treatment is prescribed, aimed at maintaining vital functions under the control of the ECG. If the measures taken do not lead to the normalization of the concentration of potassium, the use of hemodialysis or peritoneal dialysis may be considered.

Monitoring:

- the concentration of urea, electrolytes, creatinine;

– serum potassium level;

– ECG monitoring;

– in the absence of symptoms, patients are observed for at least 6 hours.

An overdose of glucose can cause hyperglycemia, hyperhydration, hypervolemia. Therapy depends on the type and severity of disorders: stopping the infusion, prescribing insulin (1 unit of insulin per 4-5 g of glucose), diuretics, electrolytes.

Precautionary measures.

The drug is administered slowly! Too rapid intravenous administration may develop hyperkalemia, which can potentially lead to death.

During treatment, it is necessary to control the level of potassium in the blood and ECG monitoring. With caution appoint in violation of AV-conduction.

It must be borne in mind that the toxicity of potassium salts increases with adrenal insufficiency.

It is also necessary to treat the lack of magnesium, which may accompany a lack of potassium.

Patients with chronic kidney disease or other conditions that interfere with potassium excretion from the body, or if the drug is administered too quickly intravenously, may develop hyperkalemia, which can potentially lead to death. It should be borne in mind that hyperkalemia, leading to death, can develop quickly and be asymptomatic.

Use with caution in diseases of the cardiovascular system, while the use of potassium-sparing diuretics.

Simultaneous parenteral administration of calcium ions can cause arrhythmia.

The drug should be used very carefully in patients with intracranial and intraspinal hemorrhages.

With prolonged use of the drug, control of blood sugar levels is necessary.

The drug should be used with caution in the elderly.

In hypokalemia replacement therapy, glucose solutions should not be used, since glucose can cause a further decrease in plasma potassium concentration.

The contents of the container can only be used by one patient, the unused portion should be discarded.

Use during pregnancy or lactation.

If necessary, use during pregnancy should weigh the expected benefit to the mother and the potential risk to the fetus. During lactation, the issue of stopping breastfeeding should be resolved.

Influence on the ability to drive a car or other mechanisms.

Since the drug is used in a hospital setting, there is no data on the effect on the ability to drive vehicles or other mechanisms.

Children. There are no data on the use of the drug in children.

Interaction with other drugs.

The drug improves the tolerability of cardiac glycosides, which allows, if necessary, the simultaneous administration of strophanthin or digitalis preparations. Potassium-sparing diuretics, ACE inhibitors, non-steroidal anti-inflammatory drugs beta-blockers, cyclosporines, trimethoprim increase the risk of hyperkalemia, which requires monitoring of potassium levels in the blood when they are used simultaneously with potassium chloride concentrate. The drug should not be administered simultaneously with blood products.

When used simultaneously with thiazide diuretics and furosemide, their ability to influence the level of glucose in the blood serum should be taken into account. Glucose weakens the action of analgesic, adrenomimetic agents, inactivates streptomycin, reduces the effectiveness of nystatin. Glucose solution should not be administered in the same infusion set as blood due to the risk of non-specific agglutination. Since glucose solution for intravenous infusion is acidic (pH<7), может возникнуть несовместимость при одновременном введении с другими лекарственными средствами.

When combined with other drugs, it is necessary to clinically monitor their possible incompatibility. The drug is incompatible with dobutamine hydrochloride, amphotericin, amikacin sulfate and parenteral fat emulsions.

Storage conditions. Store at a temperature not exceeding 25 ºС. Keep out of the reach of children.

    Tannin E 181 is used as food coloring, to give color, as well as in the manufacture of all kinds of drinks. The dye has a strongly astringent taste. Used for coloring various pastries and sweets. The solutions of colloids that are formed in water express strong tanning effects and are acidic. A large amount of tannin is found in green tea.
    Tannin E 181 is used for tanning leather and fur, for pickling cotton fibers, and for making ink.

    In addition, E 181 is widely used in medicine for the treatment of diarrhea, hemorrhoids, inflammatory diseases, to stop bleeding. You can strengthen blood vessels by drinking green tea regularly. Also used as an antidote for poisoning with mercury, lead or other toxic substances.


    At the same time, the property of Tannin is activated to slow down the absorption of various substances in the body. From the same property, harm follows from its excessive use - diseases can occur associated with a lack of any minerals (for example, iron) in the body. In addition, in sensitive people, this substance can disrupt the functioning of the liver and kidneys, and irritate the gastrointestinal tract.

Application

Tannins have acidic properties, which are due to the phenolic groups in their molecules. Therefore, they interact with proteins, as well as with metals, precipitating them. Due to this, tannins are used to stabilize wines and beer and to process (fine) wine materials, mainly white table wines, usually in combination with gelatin fining. In accordance with the Instructions for processing wine materials with gelatin, approved by the Ministry of Agriculture and Food of the Russian Federation on 05.05.98, it is recommended to use 0.5-0.75 parts of tannin from the dose of gelatin used for gluing, that is, 0.05-1.875 g / dal.

Tannins are used in the form of a 20% solution, which is prepared on the day of processing by dissolving the required amount of tannin in the processed wine material. With complex fining, tannin is introduced into the wine material a day before gelatin treatment. Tannins can be added to beer at different stages of production in amounts ranging from 0.2 to 0.7 g/l, depending on the type of beer and the technology used. In case of overdose, instead of increasing persistence, there is an increase in the haze of the beer; moreover, it tends to acquire an empty taste.

Tannins are included in the list of raw materials in GOST 28616-90 “Fruit wines. General technical conditions”, GOST 28685-90 “Sparkling wines. General technical conditions".

Other applications: for tanning leather, as a mordant for dyeing cotton fabrics, an astringent drug.

TARTRAZINE E102

    TARTRAZINE E102 is a food additive, yellow dye. It is produced artificially, as it is not found anywhere in nature in its pure form. In production, coal tar waste is used as a raw material.

    Effect on the human body:
    Tartrazine is known as one of the most harmful dyes for human health.. This explains the fact that the food additive E102 is banned in most countries. However, the food and pharmacological industries in Russia and Ukraine allow its use.

    It was revealed that tartrazine causes an allergic reaction in the form of urticaria. However, studies in America in 1986 showed that rashes and other adverse reactions to a nutritional supplement occur no more than once in 10,000 cases.

    There is evidence that the use of E102 causes a decrease in concentration and excessive activity in children. It is known that, together with sodium benzoate, tartrazine can cause Merkelsson-Rosenthal syndrome, accompanied by the formation of cracks in the tongue, Quincke's edema and damage to the facial nerves.

    Food additive E553 is allowed in the Russian Federation in accordance with the norms and TI(See Hygiene Standards below).

    Potassium tartrates - food additive E336, used in food products as an antioxidant, acidifier, acidity regulator, emulsifier. Additive E336 also stabilizes the color of products, enhances the action of antioxidants.

    Additive E336 is a mixture consisting of two organic substances that are similar in their physical and chemical properties:

    • Potassium tartrate (Potassium tartrate, dipotassium tartrate) is an average salt of tartaric acid with the chemical formula C4H4K2O6;
    • Potassium bitartrate (Potassium bitartrate) is an acid salt of tartaric acid. Chemical formula KC4H5O6. Also known as tartar, cream of tartar. Found in the juice of many berries.

    They are often confused with each other, so you should pay attention that dipotassium tartrate and potassium bitartrate are different compounds.

    In the Russian Federation and Ukraine, the use of this food additive is allowed.
    Potassium tartrates are successfully used in winemaking and in the production of food additive E334 - tartaric acid. You can find potassium salts of tartaric acid in instant soups, jellies and sweets with jelly filling, jams and marmalades. Cream of tartar is added as a baking powder to confectionery and bakery products.

    Effect on the human body:
    Since the food antioxidant E336 is of natural origin, the harm from its effect on the human body is negligible. The food supplement has an effect on the cardiovascular system, reducing the flow of venous blood. This property of cream of tartar can alleviate the condition of patients with varicose veins of the legs and colon.

SODIUM THIOSULFATE E 539

    Previously food emulsifier E 539 Sodium thiosulfate used in the food industry as an antioxidant and complexing agent, for example, to add to iodized salt and flour. But in 2010 banned in Russia. Also, this additive does not have permission in the EU.

    In the food industry, sodium thiosulfate is mainly used as an antioxidant for iodized salt and as an improver in the quality of flour and bread. As a flour improver, food additive E 539 can act as an independent component or be used in combination with a number of other similar improvers. Sodium thiosulfate is included in iodized salt in a proportion of not more than 250 mg per 1 kg of salt. In the baking process, its mass fraction does not exceed 0.002 percent of the total mass of flour or up to 50 mg per 1 kg of product. In addition to the food industry, the additive E 539 is widely used in medicine.

    It is part of complex baking improvers, and is also used as an individual baking improver of restorative action. It is recommended to use restorative improvers to change the rheological properties of wheat flour dough with excessively strong or short-tearing gluten. At the same time, the volumetric yield of bread increases, the crumb becomes more elastic, friable, cracks and undermining are smoothed out on the surface of the products.

    When used individually, sodium thiosulfate is added together with baker's yeast in the amount of 0.001-0.002% by weight of flour, depending on the method of baking bread (hearth or tin). To ensure an accurate dosage of the improver, prepare its aqueous solution in a ratio of 1:20. The solution can be stored for no more than a day in a closed vessel made of a material that is not susceptible to corrosion.

    Sodium thiosulfate is also used to stabilize iodine in the production of iodized salt in amounts up to 250 mg/kg.

    Other applications: in pharmaceuticals as an anti-inflammatory agent, an antidote for poisoning with arsenic, mercury compounds, etc.; in textile
