Sodium benzoate
Nov 14, 2017

Sodium benzoate (Chemical type: c6h5co2na), e-numbered E211, sodium benzoate. Sodium benzoate belongs to acidic preservatives in acidic environment, the antiseptic effect is good, is very commonly used food preservatives, have to prevent deterioration sour, prolong the shelf life effect, in all countries are widely used. However, concerns over its toxicity in recent years have limited its application, with some countries such as Japan ceasing to produce sodium benzoate and restricting its use.

Sodium benzoate is mostly white granules, odorless or micro-band benzoin smell, sweet taste, there is convergence, soluble in water (room temperature) 53.0g/100ml around, ph is about 8; Sodium benzoate is also acidic preservative, no bactericidal and bacteriostasis in alkaline medium The best antiseptic ph is 2.5-4.0, and the germicidal efficacy of 5% in PH5.0 is not very good. Sodium benzoate is lipophilic, it is easy to penetrate the cell membrane into the cells, interfere with the permeability of the cell membrane, inhibit the absorption of amino acids by the cell membrane, enter the alkali storage in the cells by ionization acidification, inhibit the activity of the respiration enzymes in the cells, prevent the acetyl coenzyme A condensation reaction, and thus play the purpose of food preservative
