Summary: To solve the challenge of simultaneous detection of live and dead bacteria in food safety, researchers developed an all-in-one biosensor using a phage-apoferritin@CuO2 probe on an antimicrobial peptide (AMP)/MXenes-modified detection platform. The biosensor can simultaneously measure live and dead bacteria of Escherichia coli O157:H7 through bioluminescent, colorimetric, and electrochemical signals. The biosensor was successfully used for on-site measurement of live and dead E. coli O157:H7 in food samples with a detection limit of 30 CFU/mL for live bacteria and 6 CFU/mL for total bacteria within 50 min. This work presents a novel pathway for rapid and simultaneous quantification of both live and dead bacteria.

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.
