The objective of this research was to develop a novel high-performance liquid chromatographic (HPLC) method involving a simple sample preparation procedure for the rapid, low-cost, and sensitive quantitation of phenol in honey at levels of regulatory and practical importance. After proper dilution of honey with water, the samples were analyzed by a gradient HPLC system, using a reversed-phase column with fluorescence detection at excitation and emission wavelengths of 270 and 300 nm, respectively. The eluents applied were water-acetonitrile-85% orthophosphoric acid (10:10:0.01, v/v/v) and water-85% orthophosphoric acid (20:0.01, v/v). The retention time of phenol was found to be 14.1 min, and the limit of quantitation for phenol in honey was set at 5 microg/kg. Overall recovery was 98%. The proposed method has been successfully applied to real sample analysis.

Fruits are excellent sources of substrate for various fermented products, including fruit vinegars, which are typically produced by submerged fermentation. Some evidence suggests that fruit vinegar consumption can alleviate certain disorders, including hyperlipidemia, inflammation, and hyperglycemia. Fruit vinegars also have bacteriostatic and antihypertensive actions.

Climate change significantly affects honey bee populations and their access to natural food sources, demanding alternative economic feed sources. Longan stands out as the most important fruit crop in Southeast Asia, but with a surplus of low-grade fruit that is not suitable for the market. This study investigates the potential of longan syrup as an alternative carbohydrate source for honey bees by measuring sugar composition, phytochemical profiles, feed, and survival, as well as the resulting gut microbial changes.

Honey is a complex natural nutrient with well-established therapeutic properties recognized in traditional medicine. The purpose of the current work was to compare, in vitro, the bioactive compounds, antioxidants, and antimicrobial properties of 37 honey samples collected from the western region of Algeria and to identify the best sample for potential therapeutic purposes. Estimation of bioactive compounds was carried out by determining the total phenolic and flavonoid contents.
