Characterization of honeys produced in the region of Djelfa steppe land in Algeria. Description of the subject. This paper deals with the quality of honeys produced in the steppe areas of Algeria and discusses the possibility of their valorization. Objectives. The objective was to characterize and compare the physical and chemical quality of honeys and to determine their pollen composition according to their geographical origin in three areas of the Djelfa semi-arid region of Algeria. Method. Thirty-eight samples of honey produced in 11 localities in the north, centre and south of the Djelfa semi-arid steppe region were harvested in July for two consecutive years. Pollen analyses were performed and the following properties of the honey samples were determined: water content, pH level, electrical conductivity, color, hydroxymethylfurfural content, saccharase index, diastase index and carbohydrate profile. Results. The results of the pollen analyses identified 34 taxa of pollen. The most abundant pollens were from the Ziziphus lotus, which were present in 97.12% of the samples. The pollens from this shrub were dominant in 27 of the honey samples tested, with a pollen percentage of greater than 45%. Over 55% of the pollen frequencies found came from plants belonging to Asteracae, Brassicaceae, Cistaceae and more particularly to Euphorbia bupleuroides, Peganum harmala, Thapsia garganica, Echium sp. and Retama retam. Conclusions. The physicochemical parameters of the honey samples studied comply with European and international quality standards, which opens up perspectives for their valorization.
