[ 8 ] Sodium benzoate is also allowed as an animal food additive at up to 0.1%, per the Association of American Feed Control Officials. [ 9 ]
Benzyl alcohol is subsequently metabolized to benzoic acid. The conjugates of benzoic acid ( hippuric acid and the glucuronide of benzoic acid) are rapidly eliminated in urine. [ 1 ] When given in large doses to laboratory animals, benzyl benzoate can cause hyperexcitation, loss of coordination, ataxia , convulsions , and respiratory paralysis .
It has been reported that many food preservatives, including sorbitan, hydrogen peroxide, benzoic acid and sodium benzoate, can cause health problems, especially in high doses.

Thanks to artificial preservatives, fruits, vegetables, meats and dairy products last much longer now than they naturally would, and that is not necessarily good news.
Potassium benzoate (E212), the potassium salt of benzoic acid, is a food preservative that inhibits the growth of mold, yeast and some bacteria. It works best in low-pH products, below 4.5, where it exists as benzoic acid.
Calcium benzoate refers to the calcium salt of benzoic acid. When used in the food industry as a preservative, its E number is E213 (INS number 213); it is approved for use as a food additive in the EU, [1] USA and Australia and New Zealand. [2] The formulas and structures of calcium carboxylate derivatives of calcium and related metals are ...
Benzoic acid, benzoates and their derivatives are used as preservatives for acidic foods and beverages such as citrus fruit juices (citric acid), sparkling drinks (carbon dioxide), soft drinks (phosphoric acid), pickles and other acidified foods. Typical concentrations of benzoic acid as a preservative in food are between 0.05 and 0.1%. Foods ...
