Abstract:

The aim of the present study was to contribute to increase the current knowledge about the chemical composition of multifloral honeys from Angola through the use of main physicochemical parameters. Water content, pH, free acidity, electrical conductivity, proline, hydroxylmethylfurfural (HMF), sugar content and diastase activity were analyzed. The mean values and standard deviations obtained for the physicochemical parameters were: water content 18.88±1.21%, pH 4.36±0.59, free acidity 29.36±13.51 meq/kg, electrical conductivity 0.92±0.15mS/cm and proline 565.77±312.39 mg/kg. For all honey samples hydroxymethylfurfural (HMF) values are under 20 mg/kg. The sugar content and diastase activity were also analyzed. The results obtained for multiÃ¯Â¬â€šoral honey samples from Angola indicated a good quality level according to their physicochemical parameters.

Keywords: Honey, Physicochemical parameters, Proline, Water content, Free acidity, Electrical conductivity, Sugars, Diastase, Hydroxymethyl furfural (HMF), pH
