What is sodium benzoate, what is sodium benzoate?

Sodium benzoate is also known as: sodium benzoate. cas:

532-32-1 Specifications:Industrial Grade,Food Grade [Molecular Formula]:C7H5NaO2 [Character]:

White granules or crystalline powder. Odorless, sweet and astringent. [Use]:

reagents for chemical analysis; It is used in the pharmaceutical industry and plant genetic research.

Sodium benzoate is a preservative used for internal liquid medicine, which has the effect of preventing deterioration and acidity, prolonging the shelf life, and excessive dosage will cause harm to the human liver and even cause cancer. According to GB2760-1996 national health standards, sodium benzoate shall not be used in food processing.

The purpose of adding food preservatives is to improve food quality, extend shelf life, facilitate processing and preserve nutrients. As long as benzoic acid and sodium benzoate are added in accordance with the range of varieties and the amount of use stipulated by the state, they are allowed and safe. It is true that China's food additives laws and regulations are also somewhat lacking, as a food scientist in the face of the public's unprecedented concern about food safety or the pressure of enterprises to pursue interests, should be in line with a responsible scientific attitude to demonstrate, and can not be imagined, arbitrarily misinterpret food preservatives, mislead the public, resulting in the public to lose confidence in the modern food industry and even panic.

If that happens, it will make the development of the food industry and the solution of food safety problems passive.

Sodium benzoate, also known as sodium benzoate, is a white granule or crystalline powder. Odorless, sweet and astringent. It is used as a reagent for chemical analysis as well as in the pharmaceutical industry and plant genetic research.

Sodium benzoate is also an acidic preservative, which has no bactericidal and antibacterial effect in alkaline media; The best pH for antiseptic is that the sterilization effect of 5% solution is not very good. Sodium benzoate is lipophilic, easy to penetrate the cell membrane into the cell, interfere with the permeability of the cell membrane, and inhibit the absorption of amino acids by the cell membrane; It enters the cell body to ionize and acidify the alkali storage in the cell, and inhibits the activity of the cell's respiratory enzyme system, preventing the acetyl-CoA condensation reaction, so as to play the purpose of food preservation.

As a preservative, sodium benzoate is widely used in the preservation of a variety of seafood. Due to toxicity concerns, some countries, such as Japan, have stopped producing sodium benzoate and restricted its use. Benzoate preservatives (sodium benzoate, potassium benzoate) can react with vitamin C to form carcinogenic benzene.

Benzoic acid Benzoates are found naturally in blueberries, cranberries, dried plums, cinnamon, and cloves. A small amount of sodium benzoate is non-toxic to the human body, it can be quickly absorbed in the body, mainly combined with glycine and excreted in the form of hippuric acid, and a small part is excreted with glucuronic acid as 1-benzoylglucuronic acid. 10 It can be completely excreted from the body in 14 hours, so a small amount of sodium benzoate will not have a storage effect.

However, cats are more sensitive to benzoic acid and are prone to symptoms such as excitement, nervousness, loss of hearing and balance, so it is necessary to pay attention when making pet food.

Summary. Extended Information: Benzoic acid is an aromatic acid organic compound and the simplest aromatic acid [1], with the molecular formula C7H6O2.

It was originally made from benzoin gum, so it is called benzoin acid. Melting point, boiling point, relative density (15 4) appearance of white needle-like or scaly crystals.

Sublimation at 100 or more. Slightly soluble in cold water, hexane, soluble in hot water, ethanol, ether, chloroform, benzene, carbon disulfide and turpentine.

Hello. What is the difference between sodium benzoate and benzoic acid.

Dear: Glad to solve the problem for you: sodium benzoate is not the same as benzoic acid, and the difference between sodium benzoate and benzoic acid is:

Different chemical formulas, different water solubility, and different uses. Sodium benzoate: C7H5NaO2; Benzoic acid:

c6h5cooh;Sodium benzoate: sodium benzoate is water-soluble and soluble in water; Benzoic acid is weakly soluble in water, slightly soluble in water, soluble in ethanol, ether, etc.

For medical **** diseases, it is benzoic acid or sodium benzoate that is used externally.

Kiss: Benzoic acid.

Kiss: Benzoic acid.

Kiss: Benzoic acid has the effect of relieving itching, repairing and reversing on **. Benzoic acid is an acidic substance, and different concentrations of this substance have different medicinal effects.

Extended Information: Benzoic acid is an aromatic acid organic compound and the simplest aromatic acid [1], with the molecular formula C7H6O2. It was originally made from benzoin gum, so it is called benzoin acid.

Melting point, boiling point, relative density (15 4) appearance of white needle spring clear or scaly crystals. Sublimation at 100 or more.

Slightly soluble in cold water, hexapane orange, soluble in hot water, ethanol, ethyl preether, chloroform, benzene, carbon disulfide and turpentine.

Oh. Does this benzoic acid have medical and industrial use?

I'm afraid that the use of industrial ** is not good.

Qinqin: Benzoic acid has different specifications for industrial, food, and pharmaceutical use.

Right. That kind is medical.

Kiss: Yes, there are industrial and medical, here it is recommended that you follow the doctor's instructions.

Kiss: You have to go to the pharmacy to buy the medicine, this is used on your own face, no jokes, it is not suitable for yourself!

Sodium benzoate is the sodium salt of silver benzoic acid in Sun Potato. Sodium benzoate is an acidic preservative, which has a good preservative effect in an acidic environment, and is a food preservative that is very commonly used in the banquet, which has the effect of preventing deterioration and acidity, and prolonging the shelf life, and is widely used in countries around the world. However, in recent years, concerns about its toxicity have limited its use, and some countries, such as Japan, have stopped producing sodium benzoate and restricted its use.

Sodium benzoate is mostly white particles, odorless or slightly with benzoin odor, slightly sweet, astringent, and easily soluble in water. Sodium benzoate is lipophilic, easy to penetrate the cell membrane into the cell, interfere with the permeability of the cell membrane, and inhibit the absorption of amino acids by the cell membrane; Entering the cell body ionizes the alkaline storage within the cell and inhibits the activity of the cell's respiratory enzyme system, preventing B.

1. Structural formula of benzoic acid.

2. Sodium benzoate structure.

Benzoic acid molecular formula: C6H5COOH Also known as benzoin acid, odorless or slightly benzoin smell, widely used as a food preservative, naturally found in cranberry, prune, cinnamon, cloves, is an aromatic acid, can also be added as a spice.

Sodium benzoate molecular formula: C6H5Coona It is a sodium salt of benzoic acid, odorless or slightly benzoin smell, which can be partially converted into active benzoic acid in acidic food, and the preservative mechanism is the same as benzoic acid.

Because benzoic acid is more soluble in water than sodium benzoate, stable in air, and has a strong inhibition effect on yeast and bacteria, sodium benzoate is more commonly used than benzoic acid.

Sodium benzoate is a chemical additive, mainly one of the active ingredients in preservatives, which has a certain inhibitory effect on yeast, bacteria, molds and fungi, and can be added as additives and preservatives in food and medicine. Sodium benzoate is a white, granular powder that is usually sweet-flavored and can be used as a major added ingredient in preservatives.
