Quality Attributes of Local and Imported Honeys Commercialized in Algeria

Abstract

This study was aimed to assess quality, authentication parameters and trolox equivalent antioxidant capacity (TEAC) of Algerian and imported honeys sold in Algerian markets. Results indicated that 80% Algerian samples fulfilled international standards, whereas only 21.4% imported honeys were in agreement with the current regulations. 13.3% Algerian samples and 7.1% imported honeys showed values of proline lower than 180 mg/kg, which is the recommended limit for authentic honeys. Comparing Algerian and imported honeys, electrical conductivity, degrees Brix, diastase activities and proline contents were higher in Algerian honeys, in contrast to moisture percentages, hydroxymethylfurfural contents and acid phospatase activities that were higher in imported honeys. Methanolic extracts of Algerian samples were richer both in total phenolics and flavonoids determined in alkaline medium. There were not significant differences between Algerian and imported samples concerning pH, free acid, invertase, total carotenoid, total phenolics of raw honeys and TEAC, as well as regarding total flavonoids determined in neutral medium and o-diphenols of honeys’ methanolic extracts. Principal components analysis showed a good separation between Algerian and imported samples, only one multifloral Algerian honey being misclassified. Our research showed that a legal frame for Algerian honeys is of utmost importance. Spurge-labeled honeys were grouped, showing interesting common features that should be taken into account in a future regulation, in which a protected designation of origin for spurge honeys could be considered.

Sensorial, Melissopalynological and Physico-Chemical Characteristics of Honey from Babors Kabylia’s Region (Algeria)

“…These results were included within the interval found by [ 22 ] on honey samples from the same region and close to those reported by [ 23 ] on honeys from Algeria. Furthermore, TPC values were included in the range reported by [ 24 ] on Italian honey.…”

From the Beehives: Identification and Comparison of Physicochemical Properties of Algerian Honey

“…Furthermore, to highlight the practical importance of this study, it should be noted that national honey production is currently estimated to be 33,000 kg, with a yield of 4 to 8 kg per hive. This is considered very low compared to the honey potential offered by Algeria, as the country imports more than 150,000 tons of honey per year from China, India, Saudi Arabia, and other countries [38]. Therefore, studying and reporting the physicochemical characteristics of Algerian honey samples is of high significance.…”
