- Conclusion
Potassium benzoate can be chemically synthesized by the reaction of benzoic acid (produced from the oxidation of toluene) with potassium bicarbonate, or potassium carbonate, or potassium hydroxide. Dow Chemical Company came up with a method of obtaining high yield and pure potassium benzoate by reacting benzoic acid with potassium hydroxide. (1)
Solubility
In water:73.83 g/100 mL (25 °C) in water, approximately 21 times that of benzoic acid, 3.44 g/L (25 °C). It dissociates into two distinct parts in water, the benzoate anion and potassium cation. The benzoate anion is the conjugate base of the benzoic acid. In organic solvents: soluble in ethanol, slightly soluble in methanol, insoluble in ether.
PH
The pKa of benzoic acid is 4.2. The preservation function is better in low-pH products, below 4.5 or below its pKa.
Preservation Mechanism
The mechanism of action is the same with that of sodium benzoate, and also similar to sorbates, but different with the bio preservative – natamycin. Benzoic acid forms when potassium benzoate dissociates in water and combines with proton. The undissociated benzoic acid enters the microbial cell and inhibits cell growth. This is how it works and plays a role in food preservation.
It is used less than sodium benzoate in past years, but now it seems the market demand is increasing. Potassium benzoate is used as a substitute preservative for sodium benzoate primarily in acidic foods where the sodium content needed to be lower. The following food may contain with it: 1. soda 2. juice 3. cider 4. margarine 5. syrup 6. jelly 7. d...
Yes, it has been approved as a safe preservative by European Food Safety Authority (EFSA), as well as Joint FAO/WHO Expert Committee on Food Additives (JECFA), and can be used in wide products such as fruit juice and soft drinks.
Some people may be afraid the safety of potassium benzoate when watching the house of evil owner said the toppings was bad as it contains potassium benzoate in Simpsons episode (Season 4 – Cursed Frogurt) (13). Is it really bad for you? Synthesized preservatives are the most controversial food additives although they have been approved safe. That’s...
Potassium Benzoate vs Sodium Benzoate?
The purpose of potassium benzoate is used as a low sodium preservative alternative for sodium benzoate in some food.
Does Potassium Benzoate Raise Potassium Level?
Of course, it will increase the potassium level in our body, but very little.
Is Potassium Benzoate Natural?
It is not natural. Potassium benzoate is the salt of benzoic acid. The salt is not found to occur naturally and the manufacturing process through chemical synthesis, so it is not natural.
Now I think you may have a good knowledge of the preservative – potassium benzoate (E212), from the production process, uses, approved safety and possible side effects. Also you may be clear with some common FAQs such as the comparison with sodium benzoate. What kinds of food labels have you found this ingredient in? Let me know in the comments.
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.
