Physicochemical and bioactive properties of six honey samples from various floral origins from Tunisia

Abstract

The present study was undertaken to determine the physicochemical, biochemical, and antioxidant activities of Tunisian honey samples. All the extracted honey samples appeared to conform to the European Legislation (EC Directive 2001/110) for all parameters. Mint honey, for instance, possesses significant pH value (p < 0.05), invertase activity, water, and protein contents. In addition, this study demonstrates that the color of the Tunisian honeys is highly variable and ranges from pale yellow to dark brown. The total phenolic, flavonoid and carotenoid contents significantly vary (. p < 0.05). The highest values were found in mint honey, which has a very dark color. Correlations between the analyzed parameters are statistically significant (p < 0.05). The DPPH radical scavenging activity of rosemary honey was determined as lower (p < 0.05) than the other analyzed honey samples. Yet, the highest activity was detected in mint honey. The results suggest that Tunisian honeys could be beneficially used as a functional or nutraceutical substance as they prevent or moderate oxidative stress-related diseases

Authentication of honeys from Caramulo region (Portugal): Pollen spectrum, physicochemical characteristics, mineral content, and phenolic profile

“…All samples are within the expected limit for floral honeys (0.60%), except sample CM17 whose ash value is slightly above 0.60%, indicating a possible absence of adulterations with molasses (Silva et al., ). The obtained results are consistent with those reported for other Portuguese and worldwide honeys, such as Castelo Branco (0.02% to 0.46%) (Silva et al., ), Lousã (0.11% to 0.39%) (Andrade et al., ), Luso (0.09% to 0.53%) (Silva et al., ), and Trás‐os‐Montes (0.12% to 0.32%) (Estevinho et al., ), and from other countries, namely, Tunisia (0.08% to 0.69%) (Boussaid et al., ) and Spain (0.16% to 0.60%) (Terrab et al., ).…”

Reformulation of spray‐dried apple concentrate and honey for the enhancement of drying process performance and the physicochemical properties of powders

“…TPC in fresh AC (Table ) was significantly ( P < 0.05) higher than in fresh H. The TPC value obtained in H was in an agreement with the literature data for different honeys: 320–1190 mg kg −1 , 340–4700 mg kg −1 , or 560–2460 mg kg −1 . Also, the values presented in the literature for AC, around 1300–1500 mg kg −1 , are very close to the level determined in this study.…”

Bioactive constituents, in vitro radical scavenging and antibacterial activities of selected Apis mellifera honey from Kenya

“…Positive correlation was recorded between DPPH radical scavenging activity and TPC (r s = 0.72, P ˂ 0.05) as defined in Table 3. These results are in perfect accordance with the reports of other authors (Alvarez-Suarez et al, 2010b;Sant'Ana et al, 2012;Boussaid et al, 2018).…”

“…The mean total phenols content (TPC) of Kenyan honey varied between 66.72 and 141.74 mg GA E/100 g of honey (Table ). A similar level of TPC was observed in past studies (Ouchemoukh et al , ; Attanzio et al , ; Boussaid et al , ). Generally, the concentration of phenols in honey varies depending on its botanical and geographical origin (Küçük et al , ).…”
