A Novel Umami Peptide Selector (UPS) for Identifying Key Peptides from Maillard-Reacted Chicken Hydrolyzates: From Taste Evaluation to Antioxidant Properties

Abstract The Maillard reaction (MR) enhances the flavor of chicken enzymatic hydrolyzates, yet pinpointing key umami peptides remains challenging due to complex matrices. Sensory evaluation showed increased umami intensity despite decreased equivalent umami concentration (EUC: 0....

Development of an Olfactory Receptor (OR5K1)-Based Biosensor for Pyrazine Detection in Foods

Pyrazines are the key odorants in food contributing to baked and nutty aromas. In order to improve practicality, a novel electrochemical olfactory biosensor for pyrazine analysis was developed using an olfactory receptor (OR5K1) as the recognition element and AuNPs-PB/ZIF-8@SWCNT...
