Free Acidity Testing

Test Description

Free acidity is an important parameter related to the composition of honey. It is characterized by the presence of organic acids such as gluconic acid and some inorganic ions such as phosphates, sulfates and chlorides. Higher values may be indicative of fermentation of sugars into organic acids.

The Codex Alimentarius International Food Standards (Adopted 1981, Amended 2019) permits a maximum value for free acidity of maybe not more than 50.0 meq/kg.

Test Methodology

Free acidity is measured by titration.
