Honey physicochemical parameters; Eastern Moroccan; Flora; Principal component analysis
Abstract :
[en] The principal aim of this study was to contribute more to the knowledge of the eastern Moroccan honey by means of the analysis of physicochemical characteristics with different flora of eastern Morocco. Thirty one honey samples were collected from beekeepers in different regions of eastern Morocco. In this study, pH, free acidity, electrical conductivity (EC), water content, diastase, hydroxymethylfurfural (HMF) and Protein content were all determined in different types of eight flora honey jujube, Multifloral, Citrus, Eucalyptus, thyme, carob, lavender and Rosemary. The moisture shows values of 15.39% and 19.37%, pH between 3.53 and 4.94, the free acidity ranges between 5.77 and 19.47 meq/kg, hydroxymethylfurfural (HMF) content shows values between 3.98 and 56.14mg/kg; diastase values were between 6.98 and 21.17 Gothe; electrical conductivity between 108 and 626 μs/cm and Saccharase content values range between 1.16-11.91 U.E/kg. A statistical analysis was carried out to classify eight types of honeys, and identified the most significant parameters, using analysis of variance, principal component analysis (PCA). PCA showed that the cumulative variance was 71.91%. The present study revealed that eastern Morocco honey is a good quality.
