Benzoic Acid (CAS 65-85-0) Usage
Benzoic acid and its sodium salt, sodium benzoate, are very commonly used as food preservatives. Under acidic conditions, it has an inhibitory effect on yeasts and molds. When the pH value is 3, the antibacterial power is strong, and when the pH is 6, it has a very poor effect on many molds.
The maximum usage of concentrated fruit and vegetable juices in plastic barrels used in the food industry must not exceed 2.0g / kg; the maximum usage of jams (excluding canned food), fruit juice (flavor) beverages, soy sauce and vinegar is 1.0g / kg ; The maximum usage in soft candy, wine, fruit wine is 0.8g / kg; in low-salt pickles, sauces, preserves, the maximum usage is 0.5g / kg;
The maximum amount used in carbonated beverages is 0.2g / kg. Because the solubility of benzoic acid is small, it must be fully stirred when used, or dissolved in a small amount of hot water or ethanol. When used in concentrated fruit juices for refreshing beverages, benzoic acid is commonly used as its sodium salt because it easily evaporates with water vapor.
Benzoic acid is a common antiseptic and fresh-keeping agent in the food industry, but it is not allowed to be added to dairy products. In general, benzoic acid is considered safe. However, for some special populations including infants and young children, long-term intake of benzoic acid may also cause adverse reactions such as asthma, urticaria, and metabolic acidosis.
Benzoic acid is also used as a fragrance-preserving agent for juice drinks. It can be used as an balm fragrance. It can also be used in chocolate, lemon, orange, berry, nut, candied and other food flavors. It is also commonly used in tobacco flavors.
In addition, benzoic acid is also used as a raw material for the production of pesticides, dyes, medicines, mordants and plasticizers, modifiers for polyamide resins and alkyd resins, and rust inhibitors for steel equipment.
