Intro to Sodium Benzoate

Sodium benzoate is a common food preservative and is the sodium salt of benzoic acid. Sodium benzoate is synthesized from sodium hydroxide and benzoic acid. As in food, benzoic acid can play a role in a free state, and it is mainly added to acidic foods to enhance its flavor, and has the effect of preventing deterioration and sourness and prolonging the shelf life.

Sodium Benzoate Safety

At present, sodium benzoate is a food preservative allowed in China’s GB2760, which shows that the Health Commission has recognized the safety of sodium benzoate in food at this stage. The US FDA stipulates that the content of sodium benzoate in food shall not exceed 0.1% (by weight) in Chemicalbook. A study by the International Chemical Safety Agency found that daily intake of 647-835 mg/kg body weight of sodium benzoate will not have a negative effect on health. Investigations have shown that excessive consumption of benzoic acid and its salts in the human body will cause metabolic dysfunction in the liver, increased blood pressure, abnormal heart and kidney functions, and even cause muscle acidosis, fainting, and asthma. Its application scope is shrinking day by day. Some countries such as Japan have stopped the production of sodium benzoate and imposed restrictions on its use.

Sodium Benzoate Side Effect

Storage and transportation characteristics of sodium benzoate

The warehouse is low temperature, ventilated and dry.

Sodium Benzoate In Food

Sodium benzoate is an acidic preservative that has a better antiseptic effect in acidic environments. It is a very commonly used food preservative and has the effect of preventing deterioration and acidity and prolonging the shelf life.

Sodium benzoate is mostly white powder, odorless or slightly benzoin smell, slightly sweet and astringent; easily soluble in water (normal temperature) about 53.0g/100ml, pH is about 8; sodium benzoate is also an acidic preservative, in alkali There is no bactericidal and antibacterial effect in the sexual medium; the best antiseptic pH is 2.5-4.0, and the bactericidal effect of 5% solution at pH 5.0 is not very good.
