Abstract
Honey is a highly complex biological compound that sits somewhere between the animal and plant worlds. With its wide diversity, honey offers a multitude of properties, both nutritional and therapeutic. In order to determine its physicochemical characteristics, five types of samples were collected from the southern region of Senegal. These are Eucalyptus honey, Diallium honey, Mangrove honey, Anacardia honey and Daniellia honey. These honeys are analyzed for pH, water content, electrical conductivity, ash content, acidity, hydroxymethylfurfural content and reducing sugars. The results of the physicochemical analyzes informed us that the samples have on average an acidic pH of 3.78 ± 0.29, a water content of 16.34 ± 0.81%, an electrical conductivity of 0.36 ± 0.07 ms/cm, an ash content of 0.29 ± 0.15%, a free acidity of 20.77 ± 4.72 meq/kg, an HMF content of 12.97 ± 6.01 mg/kg and a content in reducing sugars of 52.40 ± 3.33%.
The results showed that there were differences from one honey sample to another, and that they all met international standards. The physicochemical parameters studied are the most frequently used as indicators of honey quality and stability, and have a major influence on its organoleptic properties.
Key words: Honey, physicochemical parameters, honey quality, honey stability, Senegal.
