This study aimed to characterize bee products (bee bread, bee pollen, beeswax, and multiflorous honey) with the profile of phenolic compounds, total phenolic (TPC) and flavonoid (TFC) contents, and antioxidant and microbiological properties. The TP and TF contents could be ordered as follows: bee pollen > bee bread > beeswax > honey. The UPLC-PDA-MS/MS analysis allowed identifying 20 polyphenols. Sinapic acid dominated in bee pollen, gallic acid in the bee bread and honey, while pinobanksin was the major compound of beeswax. The data showed that bee pollen and bee bread had a stronger antioxidant potential than honey and beeswax. Moreover, the antibacterial activity of the bee products was studied using 14 bacterial strains. Bee bread's and bee pollen's antimicrobial activity was higher towards Gram-negative strains. In comparison, honey was more potent in inhibiting Gram-positive bacteria. Our study indicates that bee products may represent valuable sources of bioactive compounds offering functional properties.

An innovative 4D targeted method was developed for the determination of 61 bioactive compounds in royal jelly (RJ) related to their health-promoting properties. The method, apart from high-resolution mass spectrometry, exploits the advantages of vacuum-insulated probe-heated electrospray ionization source (VIP-HESI), reducing thermal degradation, and trapped ion mobility spectrometry (TIMS), improving selectivity and compound identification. The optimization of VIP-HESI ionization parameters using experimental designs showed that the critical parameters were the capillary voltage as well as the probe gas flow rate and temperature.

This study examined quality changes in () stingless bee honey subjected to thermal treatment and stored at room temperature. Honey was heated at 55, 75, and 90 °C for 10 or 20 min and then stored at 30 °C for 40 days. Physicochemical parameters including moisture content, total soluble solids (TSS), pH, acidity, viscosity, hydroxymethylfurfural (HMF), color (L*, a*, b*), antioxidant activity, and total phenolic content were analyzed.

Exposure to certain pesticides and high temperatures can influence the cognitive ability of insect pollinators, such as bees, but little is known about how these stressors interact. As central place foragers, bees must learn and remember floral cues, and so impaired memory may influence foraging efficiency and fitness.

The diamide insecticide cyantraniliprole (CYA) and the triazole fungicide difenoconazole (DIF) are frequently co-detected in bee-related matrices. However, the interactive effects of these compounds on honey bee (Apis mellifera L.) physiology remain insufficiently elucidated.
