What is Sodium Benzoate?

Sodium Benzoate, also called salt benzoate, is a frequently made use of food preservative in my nation’s food market. Steady in air, can soak up dampness in subjected air. In an acidic setting, sodium benzoate has a considerable inhibitory effect on a range of microbes. the result on many molds and yeasts is poor. Almost pointless in alkaline service. After Salt Benzoate goes into the body, in the process of biotransformation, it integrates with glycine to create uric acid, or integrates with glucuronic acid to develop glucuronide, and all of them are excreted from the pee without accumulation in the body. Within the typical dose range, it is safe to the body and also is a relatively safe preservative.The appropriate daily consumption (ADI) for humans is <5 mg/kg body weight (as benzoic acid).

Sodium Benzoate has high lipophilicity, conveniently passes through the cell membrane layer as well as enters the cell body, disrupts the leaks in the structure of the cell membrane layer, as well as hinders the absorption of amino acids by the cell membrane layer; it enters the cell body to ionize and also acidify the alkali storage in the cell, and also inhibit the task of the cell’s respiratory enzyme system. Avoid acetyl-CoA condensation reaction, so as to attain the objective of food conservation.

Sodium Benzoate Uses

  1. Sodium Benzoate is utilized in the pharmaceutical market as well as plant hereditary research study, in addition to dye intermediates, fungicides and preservatives.
  2. Salt Benzoate is additionally an essential acid-type food preservative. Converts to the effective kind benzoic acid on use. Please describe benzoic acid for usage range as well as usage quantity. In addition, it can also be made use of as a chemical for feed.
  3. Salt Benzoate is made use of as a cosolvent for serum bilirubin assays. fungicide. chemical. Dye Intermediates.
  4. Salt Benzoate is used as a food chemical, in addition to in the prep work of medicines, dyes, etc.

Sodium Benzoate Safety and Limitation of Use


The safety of sodium benzoate has been controversial in recent years. For example, according to the oral LD50 index of rats in toxicology, sodium benzoate is 2700mg/kg, while potassium sorbate is 4920mg/kg (FAO/WHO, 1994). At present, sodium benzoate is a food preservative allowed in my country’s GB2760, which shows that the National Health Commission recognizes the safety of sodium benzoate in food at this stage. The US FDA stipulates that the sodium benzoate content in food should not exceed 0.1% (by weight). A study by the International Agency for Chemical Safety found that daily intake of sodium benzoate of 647-835mg/kg body weight did not have negative health effects. A survey has shown that excessive consumption of benzoic acid and its salts in the human body will cause metabolic dysfunction in the liver, increase in human blood pressure, abnormal heart and kidney function and other adverse phenomena, and even lead to muscle acidosis, fainting and asthma. Its application scope is shrinking day by day, and some countries such as Japan have stopped producing sodium benzoate and restricted its use.

Usage Limits:

GB2760-2002: Same as “07001, Benzoic acid”. Gum tissue gum base GMP (computed as benzoic acid); pre-mixed a glass of wine 0.2 g/kg. FAO/WHO (1984, mg/kg): margarine, table olives, jams as well as jellies, pickled cucumbers, pineapple juice with preservatives 1000 (alone or with acids, sorbic acid and its salts and sulfites) The amount of sulfites is not greater than 500, which is just used for production); mango sauce 250; quick-frozen angle strips, fish items, fish dental filling, GMP. FDA, § 18.1733 (2000 ): 0.1%. Japan (determined as benzoic acid, g/kg, this product g): relish 2.5 (this product 2.95); refreshing beverages, syrup and soy sauce 0.6 (this product 0.7); margarine 1 (such as with sorbic acid as well as its salts) When utilized in mix, the combined quantity is 1); fruit jams as well as fruit juices (including concentrated fruit juices) for pastry shop products are 1.0.

The Production Method of Sodium Benzoate

By benzoic acid as well as sodium bicarbonate and also acquired. Add water and also sodium bicarbonate to the neutralization pot, heat to steaming as well as liquify right into sodium bicarbonate remedy. Add benzoic acid under mixing until the pH of the reaction solution is 7-7.5. Home heating to make carbon dioxide getaway, add activated carbon to decolorize for half a hr. Suction filtering, the filtrate is focused and after that gradually take into the liquid tray of the flake equipment, dried in a drum and also pulverized to get sodium benzoate. Intake of benzoic acid (99.5%) 1045kg/t, sodium bicarbonate (98%) 610kg/t.

Environmental Fate/Exposure Summary for Sodium Benzoate

The production and also use of salt benzoate as an antimicrobial and chemical in food, sodas, pharmaceuticals, tobacco, and cosmetics, in addition to as a rust prevention as well as chemical intermediate, might result in its release right into the setting via various waste streams. If launched right into air, the approximated vapor pressure at 25 ° C is 2.9X10-12 mm Hg, showing that salt benzoate will only exist in the particle stage in the atmosphere. The particle stage sodium benzoate adsorbed on atmospheric aerosols is deteriorated in the environment by reaction with photochemically produced hydroxyl radicals; the half-life of this response in air is estimated to be 4.3 days. The particle stage sodium benzoate will certainly be gotten rid of from the environment by damp and also dry deposition. If launched into dirt, benzoic acid is not unpredictable in a liquid atmosphere. Based on its vapor stress, salt benzoate is not anticipated to vaporize from completely dry soil surfaces. Biodegradation is expected to be an important environmental destiny process for dirt and water, as different biodegradation screening tests have actually located that salt benzoate is easily biodegradable. If launched right into water, sodium benzoate is not expected to adsorb right into put on hold solids and also sediments based upon the estimated Koc. Due to dissociation in water, volatilization from the water surface is not expected to be an essential destiny procedure. An estimated BCF of 3 shows a reduced potential for bioconcentration in aquatic microorganisms. Hydrolysis is not anticipated to be a crucial ecological destiny process because this compound lacks useful groups to hydrolyze under ambient problems. Job-related direct exposure to sodium benzoate can occur with inhalation and dermal direct exposure to salt benzoate in work environments where salt benzoate is produced or made use of. Use data recommend that the basic populace might be exposed to sodium benzoate through ingestion of food and also drinks and also with skin contact with consumer items containing sodium benzoate.
