“…Honeys from the Sudanese zone have higher TPC values than honeys from the Guinean and Sudano-Guinean zones ( Figure 2(a) ). The TPC values measured in this study are higher than those obtained (16.02–120 mg/100 g) by Reshma et al [ 24 ], Can et al [ 35 ], and Buba et al [ 38 ] but are similar to the results reported by Djossou et al [ 36 ] and Ouchemoukh et al [ 39 ]. TFC of honeys ( y = 10.105 x − 0.1569; R 2 = 0.9989) ranged between 1.43 ± 0.00 and 29.81 ± 0.07 mg CAE/100 g of honey.…”

The physicochemical and phytochemical analyses of honeys (n = 50) from Sudanese, Sudano-Guinean, and Guinean areas of Benin were investigated. Results showed that dark amber is the dominant color. Moisture content ranged from 15.50% to 23.50%, and 72% of honeys respected the Codex Alimentarius recommendation. pH varied between 2.87 and 6.15, and free acidity ranged from 9.00 to 39.00 meq/kg. Electrical conductivity varied from 0.37 to 1.43 mS/cm. The content in fructose varied from 21.67% to 94.21%, and proline content ranged between 306.31 and 1187.93 mg/kg. All physicochemical characteristics varied with the areas. A negative correlation was found between pH and moisture content (r = −0.55; p < 0.01). A positive correlation was established between pH and conductivity (r = 0.79; p < 0.01) and between proline and color (r = 0.44; p < 0.01). Total phenolic content varied between 55.97 and 224.99 mg GAE/100 g, and flavonoid content ranged between 1.43 and 29.81 mg CAE/100 g. Flavonoid was positively correlated with color (r = 0.78; p < 0.01) and proline (r = 0.47; p < 0.01). Tukey's test revealed differences between total phenolic and flavonoid contents of honeys from five areas (p < 0.01). In general, Sudanese and Sudano-Guinean honeys showed potential toward therapeutic applications because of their high phenolic contents.

The palynological and physicochemical analysis of 62 honey samples produced in different biogeographical areas of Algeria was conducted. Results showed high variety in the botanical origin of samples and their physicochemical profile. Twenty-six samples were polyfloral honey, 30 were unifloral honey from different botanical sources such as Eucalyptus, Citrus, Apiaceae, Punica, Erica, Rosmarinus, Eriobotrya, or Hedysarum, and 6 were characterized as honeydew honey. Pollen analysis allowed the identification of 104 pollen types belonging to 51 botanical families, whereas the physicochemical profile showed important variations between samples. Multivariate techniques were used to compare the characteristics of samples from different biogeographical areas, showing significant differences between humid-area samples, located in the northeast of the country, and samples taken in semiarid, subhumid, and arid zones. Principal-component analysis (PCA) extracted nine components explaining 72% of data variance, being 30%, the sum of Component 1 and Component 2. The plot of both components showed samples grouped upon botanical and geographical origin. The results of this paper highlighted the great variability in honey production of Algeria, evidencing the importance of honey characterization to guarantee authenticity and to valorize local production.

“…Some papers stress the compliance/ lack of compliance of some Algerian honeys with international standards (Ouchemoukh, Louaileche, & Schweitzer, 2007;Otmani et al, 2019), whereas other studies highlight the importance of Algerian honeys characterization and/or the possibility of obtaining specific quality labels (Makhloufi et al, 2010;Haderbache, Mouna, & Arezki, 2013;Mekious et al, 2015;Ouchemoukh et al, 2017;Zerrouk et al, 2018). Antioxidant activity and parameters related to this capacity have been less researched in Algerian honeys (Khalil et al, 2012;Mouhoubi-Tafinine, Ouchemoukh, & Tamendjari, 2016;Habati et al, 2017;Ouchemoukh et al, 2017;Otmani et al, 2019). Strategic improvements in beekeeping are well-known to have a positive impact on economic development (Ramadani et al, 2019;Sari et al, 2020), which is of paramount importance in North African countries.…”

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.
