Sodium benzoate powder Usage and Synthesis.

After sodium benzoate enters the human body, in the process of biological transformation, it combines with glycine to become uric acid, or combines with glucuronic acid to become glucosinolates, and all of them are discharged from the urine, and do not accumulate in the body.

Within the normal dosage range, it has no toxic effect on human body and is a safer preservative. It can be used in carbonated beverages, concentrated fruit juice, margarine, gum mother sugar gelatin base, jam, jelly, soy sauce and so on. The Allowable Daily Intake (ADI) for humans is <5 mg/kg body weight (in benzoic acid).

Sodium benzoate is lipophilic, easy to penetrate the cell membrane into the cell body, interfere with the permeability of the cell membrane, inhibit the absorption of amino acids into the cell membrane; into the cell body ionisation acidification of intracellular alkali storage, and inhibit the activity of cellular respiratory enzymes, to prevent the acetyl-coenzyme A condensation reaction, so as to play a food preservation purposes.

Uses of Sodium benzoate powder.

1.Sodium benzoate can be used as food additives (preservatives), bactericides in the pharmaceutical industry, mordant in the dyestuff industry, plasticiser in the plastics industry, and also used as intermediates in organic synthesis, such as fragrances.

2. Co-solvent for serum bilirubin test.

3. Used in pharmaceutical industry and plant genetic research, also used as dye intermediates, fungicides and preservatives.

Safety of Sodium benzoate powder.

Studies by the International Chemical Safety Agency (ICSA) have found that daily intake of sodium benzoate at 647-835mg/kg body weight does not cause negative health effects.

Some surveys have shown that excessive consumption of benzoic acid and its salts by human beings can lead to metabolic dysfunction of the liver, elevated blood pressure in the human body, abnormal heart and kidney functions and other adverse phenomena, and even cause muscle acidosis, fainting and asthma, so its application is increasingly narrowing, and some countries, such as Japan, have already ceased the production of sodium benzoate and have imposed restrictions on its use.

Product Method of Bulk Sodium benzoate powder.

Obtained by neutralising benzoic acid with sodium bicarbonate. Add water and sodium bicarbonate to the neutralisation pot, heat to boiling to dissolve into sodium bicarbonate solution.

Put benzoic acid under stirring, until the pH of the reaction solution is 7-7.5. heat to make carbon dioxide escape, add activated carbon decolourisation for half an hour. Filtering, the filtrate is concentrated and slowly put into the liquid disc of the tableting machine, the tablets are dried by roller drying, crushed, and sodium benzoate is obtained. Consumption quota benzoic acid (99.5%) 1045kg/t, sodium bicarbonate (98%) 610kg/t.
