Sodium benzoate CAS: 532-32-1
Sodium benzoate, also known as sodium benzoate, is a commonly used food preservative in the food industry in our country. It has an odorless or slightly benzoic smell and a sweet and astringent taste. It is stable in the air and absorbs moisture when exposed to the air. Naturally present in blueberries, apples, plums, cranberries, prunes, cinnamon and cloves, its bactericidal performance is weaker than benzoic acid. The bactericidal power of 1.180g sodium benzoate is about equivalent to 1g benzoic acid. In an acidic environment, sodium benzoate has obvious inhibitory effects on a variety of microorganisms. When the pH is 3.5, 0.05% solution can completely inhibit the growth of yeast, but when the pH is above 5.5, it has poor effect on many molds and yeast. It has almost no effect in alkaline solution. After sodium benzoate enters the human body, in the process of biotransformation, it combines with glycine to form uric acid, or combines with gluconic acid to form glucosidic acid, and is completely excreted from the 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 gum base, jam, jelly, soy sauce, etc.
