Q. Show the pH range of natural honey?
The pH of natural honey ranges from 3.4 to 6.1. Acidity of honey is primarily due to presence of acids such as gluconic acid, pyruvic acid, malic acid, citric acid and succinic acid. Acidity of fresh honey is usually very low, 13 to 35 mEq/kg. Honey with acidity more than 40 mEq/kg is considered as poor in quality. Acidity is determined by titration of a known weight of honey with 0.1M NaOH. Finally, let us look at the marking regulations for honey.
