Summary: Electrochemically deposited ZnO nanoparticles on a pencil graphite electrode coated with graphene provide a highly conductive and selective electrochemical sensing electrode for cortisol estimation. Various spectroscopic and microscopic techniques were used for surface morphological analysis, while XRD and FTIR were employed for structural characterization. The DPV analysis showed a linear range of 5 x 10(-10) M - 115 x 10(-10) M with a low limit of detection value of 0.15 nM, demonstrating excellent functionality for salivary cortisol determination at low concentrations.

Summary: Honey is experiencing a resurgence in evaluation for antimicrobial and wound healing applications due to its ability to inhibit various bacteria, fungi, and viruses, as well as promote wound healing. Its activity is attributed to the enzymatic generation of hydrogen peroxide and other non-peroxide factors. The development of tissue engineering approaches has been driven by the difficulty of delivering honey's active ingredients to the wound site.

Summary: A new non-enzymatic carbon paste biosensor was developed using Multiwalled Carbon Nanotube (MWCNT) modified Myoglobin (Mb) for the determination of Bisphenol-A (BPA). The biosensor's measurement principle is based on the inhibition effect of BPA on the heme group of myoglobin in the presence of hydrogen peroxide. Differential pulse voltammetry (DPV) method was used for measurements in a potential range of (-0.15 V & +0.65 V) with K4[Fe (CN)6] as the medium. The biosensor showed a linear range of 100-1000 μM for BPA, with a response time of 16 s and a detection limit of 89 μM.

Summary: Consumers often believe that natural food is harmless, however naturally occurring toxins in food represent a health risk to humans. Toxic honey, collected by bees from poisonous plants, contains plant toxins such as grayanotoxins and triptolides that can be fatal if consumed. Understanding the toxicity mechanisms of different toxins, preventing toxic honey from entering the food chain, and developing effective antidotes and treatments are critical challenges.

Summary: Researchers identified potential allergens in Brassica napus bee pollen and found that fermentation could decrease their allergenicity while increasing the content of oligopeptides and amino acids. Immunoblot analysis confirmed the decrease in IgE-binding affinity after fermentation. Fermentation also promoted the biosynthesis of important amino acids and their precursors or intermediates. These findings suggest that fermentation has the potential to reduce allergenicity and improve the nutritional properties of bee pollen.

Summary: This study determined the concentrations of chlorinated paraffins (CPs) in honey collected from Chinese apiaries in 2015 and 2021. It was found that while the total CP concentrations in honey remained relatively stable, the ratio of medium-chain CPs (MCCPs) to short-chain CPs (SCCPs) was higher in 2021 compared to 2015. The CP congener profiles in honey were similar, with MCCP concentrations higher than SCCP concentrations. Migration tests showed no significant migration of CPs from plastic bottles into honey during storage. Overall, the risks of CPs in honey to humans are low.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
