Honey is a natural substance synthesized by honeybees. Its physicochemical properties and antioxidant activities differ among honey types due to floral and entomological origins. This is a comparative study on the physicochemical and antioxidant properties of honey from and L. (stingless bee) collected from different sources. honey samples were collected from hives ( = 13) and local markets ( = 13). honey samples were collected from local markets ( = 13). The honey samples were designated as fresh honey directly collected from hives (AMFH), honey collected from the local markets (AMMH), and stingless bees () honey collected from markets (MBH). Physicochemical and antioxidant properties were analyzed using standard protocols. The antioxidant properties of the honey samples were assessed using total phenolic, flavonoids, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) methods. Honey from the stingless bee (MBH) had significantly ( < 0.0001) higher (33.5 ± 3.0%) moisture content, free acidity (113 ± 5.0 meq/kg), and maltose (3.1 ± 1.0), but significantly lower ( < 0.001) levels of hydroxymethyl furfural (4.4 ± 2.0 mg/kg), pH (3.0 ± 0.0), EC (0.25 ± 0.0 mS/cm), fructose (19.6 ± 2.4%), glucose (18.2 ± 1.62%), and sucrose (0.18 ± 0.13, < 0.05) compared to honey collected from markets. Honey from the stingless bees had higher phenolic (273 ± 9.0 mgGAE/100 g), flavonoid (41 ± 21 mgQE/100 g), and antioxidant content (104 ± 6.0 mgAAE/100 g); however, the differences were not statistically significant ( > 0.05). Honey samples from the stingless bees had higher moisture, phenolic, flavonoid, and antioxidant contents but lower pH, HMF, sugar, ash, and electrical conductivity compared to honeys collected from markets. honey collected directly from the hive had higher quality than those purchased from markets. A strong awareness creation program is needed for consumers as well as honey producers to maintain the quality of honey.

The aim of the present study was to compare the antioxidant, antibacterial and antiviral activities of Podkarpackie coniferous honeydew honey and Manuka honey. The quality of tested honey samples (honeydew-12 and Manuka-4) regarding honey standard was evaluated as well as additional indicators (methylglyoxal, total phenolics and HPTLC phenolic profile, antioxidant potential, glucose oxidase activity, and hydrogen peroxide) were compared. Antibacterial potential was analyzed against Gram-positive (S.

Here we covalently constructed abundant long-chain hydroxyl groups-functionalized magnetic microporous organic networks (MMON-2OH) for detection of eight Triazine herbicides (THs) in honey and water samples. MMON-2OH owned a high surface area (287.86 m²/g), enhanced water compatibility, and increased exposure of long-chain hydroxyl groups, which significantly improved enrichment capacity for THs.

Acute lymphoblastic leukemia is the most prevalent form of leukemia in children and adolescents. Despite high survival rates due to advanced treatments, these therapies often result in significant treatment-related adverse effects. This scoping review explores dietary supplementation strategies for managing these adverse effects in pediatric leukemia patients.

Cationic surface-active agents (CSAAs) can persist in ambient water, be ingested by bees, and contaminate honey. Residues of CSAAs in honey remains unknown. This study measured the residual levels of five CSAAs in 271 honey samples from China using ultrahigh-performance liquid chromatography coupled with triple-quadrupole tandem mass spectrometry.

This study evaluated the concentrations of tetracycline, erythromycin, and sulfonamide in beef, eggs, and honey products sold at grocery stores and whether standard cooking to 160 °F (71 °C) reduced the concentrations of antimicrobials spiked into the evaluated food products. In June 2021, the concentrations of selected antimicrobials in 65 samples (8 beef, 48 eggs, 9 honey samples) purchased from grocery stores within Knoxville, Tennessee, were measured using enzyme-linked immunosorbent assays. The Kruskal-Wallis test was used to assess the differences in the median tetracycline concentrations across food types, while the Mann-Whitney test was used to compare the erythromycin residue concentrations between beef and honey.
