Sodium benzoate CAS#532-32-1

Products Description of Sodium benzoate CAS#532-32-1

In 1870, when British scientist H. Fleck was looking for an acid to replace the well-known salicylic acid, he first described the antiseptic effect of benzoic acid. He established the antiseptic effect of this substance. Since the safety research of sodium benzoate was not in-depth at that time and the production technology was not mature enough, it was not used for food preservation until the beginning of this century. Since then, it has become one of the most used preservatives in the world because of its low price. Sodium benzoate, also known as sodium benzoate, is a commonly used food preservative in my country's food industry. It is odorless or has a slight smell of benzoin and a sweet and astringent taste. It is stable in the air and can absorb moisture when exposed to the air.

 It is naturally present in blueberries, apples, plums, cranberries, cranberries, prunes, cinnamon and cloves. Its bactericidal performance is weaker than that of benzoic acid. The bactericidal power of 1.180g of sodium benzoate is approximately equivalent to 1g of benzoic acid. In an acidic environment, sodium benzoate has a significant inhibitory effect on a variety of microorganisms. When the pH is 3.5, a 0.05% solution can completely inhibit yeast growth, but when the pH is above 5.5, the effect on many molds and yeasts is poor. It has almost no effect in alkaline solutions. 

After sodium benzoate enters the human body, it combines with glycine to form uric acid, or combines with glucuronic acid to form glucuronide during the biotransformation process, and is completely excreted from the body through urine, and does not accumulate in the body. Within the normal dosage range, it has no toxic effect on the human body and is a safer preservative. It can be used in carbonated beverages, concentrated fruit juices, margarine, gum base, jams, jellies, soy sauce, etc. The human body's acceptable daily intake (ADI) is <5 mg/kg body weight (in terms of benzoic acid).
