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 acceptable daily intake (ADI) for human body is <5mg/kg body weight (in benzoic acid).

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

Uses and functions of Sodium Benzoate powder.

1. Sodium benzoate can be used as food additive (preservative), bactericide in pharmaceutical industry, mordant in dyestuff industry, plasticizer in plastics industry, and also used as intermediate in organic synthesis such as spices.

2. Co-solvent for serum bilirubin test.

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

Preparation of Sodium Benzoate powder.

Product Method of Bulk Sodium Benzoate powder.

Obtained by neutralizing benzoic acid with sodium bicarbonate. Add water and sodium bicarbonate to the neutralization 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 decolorization for half an hour.

Filtering, the filtrate is concentrated and slowly put into the liquid disk of the slicing machine, dried by roller slicing, crushed, sodium benzoate. Consumption quota benzoic acid (99.5%) 1045kg/t, sodium bicarbonate (98%) 610kg/t.
