About the benefits of calcium chloride E509 for our body and industrial production of goods for various purposes. Food supplement E509 You might also like

Calcium chloride (food additive E509) is a colorless (whitish in some cases) crystals that dissolve well in alcohol and water and freeze at low temperatures.

Calcium chloride is obtained during the production of soda, where it is formed as a by-product, or when limestone is treated with soda. The chemical formula of calcium chloride is CaCl 2.

Calcium chloride was registered as a food additive and is now actively included in food. According to the E509 classification, it belongs to the group of emulsifiers and is most often used in the food industry as a hardener. Basically, this additive is actively used in the production of cottage cheese, cheese and milk powder. In the latter case, it serves to thicken the product, since calcium ions perfectly bind proteins, and also to increase its final amount. Sometimes lime water (a concentrated solution of calcium hydroxide) is added to the cream in the process of separating them from whole milk: this helps to reduce their acidity before pasteurization and processing into butter. The skim milk is then acidified separately, separating casein, which then serves for other purposes. In addition, food additive E509 can be found in marmalade and jelly, as well as canned fruits and vegetables. In the latter case, it preserves the firmness of the product, and also makes its taste more salty. Also calcium chloride is used in the production of caviar and vegetable and fruit juices. The additive compensates for the calcium level in dairy products (milk loses a certain amount of calcium during pasteurization). In some cases, calcium chloride is added to confectionery products, such as chocolate, and actively resists the hardening of the product. On rare occasions, E509 is used in brewing where it serves to correct the imperfections of the water used to make beer.

In Russia, the use of such an additive is strictly regulated. It is considered safe in the European Union and can be used as an ingredient in certain foods and medicines. The daily intake of calcium chloride should not exceed 350 mg. Otherwise, the additive can cause intestinal irritation, and in some cases even lead to ulcers.

Other areas of application:

• in the chemical industry (as a reagent in analyzes);
• in the manufacture of rubber;
• in the manufacture of products from latex and natural rubber;
• in the production of glue;
• in medicine (for the production of lactic acid);
• in the production of calcium metal;
• in the CNG filling station;
• in refrigeration;
• in gas production - in the preparation of gas transportation;
• in the road sector (as an anti-icing agent and an anti-dusting agent for gravel roads);
• in the manufacture of certain drugs.

We are all accustomed to the fact that chemical synthetic food additives only harm the human body. However, this is not the case. There are such artificially derived substances that bring much more benefit than potential danger. One of these safe substances is the stabilizer and emulsifier E509, popularly known as calcium chloride.

The safety of such a food additive has been proven in the course of many scientific studies and experiments, thanks to which calcium chloride has received official approval for use in various industries, including the food industry.

Physical and chemical properties of the product

There are other names for calcium chloride: calcium chloride, calcium chloride nitrate, E509. Molecular formula of the substance: CaCl 2.

Such a food supplement is presented in the form of crystal-like granules, often white, less often completely transparent.
The substance has high moisture absorption, dissolves well in alcoholic liquids and. Resistant to high temperatures. The melting point of calcium chloride is seven hundred and seventy-two degrees Celsius, and boils at a temperature of 1935 degrees Celsius. At the same time, an aqueous solution of a substance crystallizes at temperatures below twenty degrees Celsius.

Such a food additive is obtained in the production of soda, namely in the recovery of ammonia.

Application of the substance in the food industry

On the territory of the Russian Federation, the use of this substance is not prohibited, but is strictly controlled by law. The European Union also considers calcium chloride to be a fairly safe product and is legally used in the medical and food industries.

As a food additive, calcium chloride is included in a wide variety of foods to stabilize some of their properties, as well as an emulsifier and preservative. Most often it can be found in dairy and fermented milk products, especially in pasteurized ones. But it is also available in various types of cheeses.

This substance is used in the food industry for the following processes:

1. During pasteurization, the addition of calcium chloride to them significantly reduces the acidity, which facilitates the process of making butter.
2. It is indispensable as a thickening component in the production of milk powder. The fact is that calcium ions help to better adhere to each other. Such a substance allows to normalize the process of coagulation of dairy products in the process of pasteurization and improves the formation of a clot. Adding it to milk increases its final yield and leads to a significant improvement in quality.
3. The additive marked E509 acts as a stabilizer in the manufacture of chocolate, preventing its hardening.
4. In the production of curd, calcium chloride helps the milk to coagulate better.
5. In the manufacture of marmalade, calcium chloride also acts as a stabilizer.
6. This substance prevents the softening of vegetables and fruits during the preservation process, and also normalizes the taste, bringing it to the desired salting.
7. In the manufacture of beer and soft drinks, such a product is used to reduce the hardness of water and improve its performance, as well as to regulate acidity.

Application in other fields

Due to its beneficial qualities, calcium chloride is widely used in various areas of life. It is a popular product in the medical and pharmaceutical industries, and is often included in various medications aimed at improving blood clotting, as well as antihistamines.

Food emulsifier E509 is used for the following processes:

• production of latex goods and rubber products;
• for the production of lactic acid;
• in the production of glue;
• for the production of rubber products;
• when laying asphalt, improving its adhesion;
• used as an anti-dust and anti-icing agent;
• in preparation for gas transportation;
• in the manufacture of metallic calcium;
• with a decrease in the dew point and dehydration of gas at gas distribution stations and autogas filling compressor plants.

Useful and harmful properties of E509 additive

No matter how safe the substance is, it must be consumed in acceptable dosages. The daily allowance for an adult is 350 mg of calcium chloride. And this dose is considered absolutely harmless and safe.

Negative and unpleasant consequences can occur when the permissible dosages are increased. The use of this emulsifier in large quantities irritates the digestive organs, in the most serious situations this can lead to the development of gastric ulcer.

However, the beneficial properties of this substance significantly exceed the potential harm. These include:

• help in the formation of bone tissue;
• compensation of calcium in the human body, which has a positive effect on the nervous system and muscle tissue contraction;
• regulation of blood clotting;
• helps to increase the body's natural defenses and its resistance to various infectious diseases;
• positive effect on the heart muscle;
• an obstacle to the onset and development of inflammatory processes.

In addition, calcium chloride is often used for weak labor, for liver diseases such as hepatitis or toxic liver damage. It is often used for skin diseases: eczema. Calcium chloride is used for inflammation caused by endometritis, as well as for severe allergic reaction of Quincke's edema.

In pediatric practice, calcium chloride is often used to relieve symptoms of various allergic reactions caused by the use of allergenic foods or medications. It is also prescribed to babies after vaccinations to relieve unpleasant symptoms.

Instead of conclusions

Calcium chloride is a chemical with such beneficial properties that it is widely used in medicine and food. Products prepared using such a food emulsifier are marked with the E509 mark. In medicine, calcium chloride has proven itself remarkably as a panacea for various pathologies. In addition, its valuable qualities are successfully applied in other areas of the industry. However, it is worth remembering that although this substance is harmless, it must be used in strictly regulated dosages in order to avoid unnecessary unpleasant consequences.

Calcium dichloride (CaCl 2) is a calcium salt of hydrochloric acid, externally presented as a powder of white crystals, with a density of 2.15 g / cm³, at a melting point of -772 C, boiling point - 1960 C. It is a food additive labeled E-509, and serves as a hardener, it is considered absolutely harmless. The food emulsifier is a by-substance during the production of soda (ammonia recovery).

Additive E 509 is added in such cases:

In the countries of the European Union and the Russian Federation, the emulsifier has no contraindications and is fully approved for use in the food industry, however, it is strictly regulated. This is due to the fact that with increased amounts of the emulsifier can lead to irritation of the gastrointestinal tract, and sometimes even to an ulcer. The maximum daily dose of food emulsifier is 350 mg.

There are many positive properties when calcium chloride affects the body. It is directly used in cases where the body lacks calcium, which is necessary for impulsive movements and muscle contraction. It has a beneficial effect on the cardiovascular system, thickening and stopping external and internal bleeding. Due to the presence of calcium hydrochloric acid in the body, the progression of the inflammatory process is prevented, and resistance to various infections increases.


Calcium dichloride acts as a kind of immunity for the body, which not only prevents inflammatory processes, but also increases the body's resistance, restores calcium, also gives a good taste to the finished product and is absolutely harmless. Therefore, when familiarizing yourself with the composition of a particular product, one should not forget about the benefits of the E-509 additive and, by mistake and ignorance, put it on a par with other dangerous and harmful additives of the “E” marking.

Benefits of Calcium Chloride for Children and Adults

Doctors recommend calcium chloride for adults if:

• Liver problems associated with toxic damage.
• Serum disease.
• Hepatitis of various groups.
• Quincke's edema.
• Psoriasis and eczema.
• Endometritis.

Preparations containing this supplement can only be prescribed by a specialist. If used incorrectly, if the dosage is violated, there may be negative consequences:

• Pulse slows down.
• Heartburn appears.
• It can hurt in the stomach.

• During the period of active growth.
• During allergies.
• During the period of illness with inflammatory processes.

Calcium chloride has a bitter taste, which is why children do not like it. At the same time, it helps to fight allergic manifestations of:

• Vaccinations.
• Various products.
• Pollen of flowers.
• Apiary products.
• Medicines.

All of the above applies to potassium chloride as a medicine. At the same time, the food additive (E 509) is also useful, does not contain harmful ingredients. E 509 is produced in the form of a white powder, which can be safely added to the preservation of vegetables, fruits and berries.

Of course, calcium chloride in large quantities will not be beneficial. But as you know, everything should be in moderation, no matter what product it is.

Interesting to know! Calcium chloride is used not only in the food industry, but is also used:

• Manufacturing of products from natural rubber.
• Manufacturing of latex and rubber products.
• Used as an anti-icing agent.
• It is a chemical reagent.
• It is added in the manufacture of some narcotic drugs.
