Increasing the essential oil (EO) concentration enhanced key parameters of set yogurt: The water-holding capacity increased from 0.64 (control) to 0.98 (10‰) (p < 0.05). Rheological behavior was altered, with the crystalline angle (2θ) decreasing to approximately 20°. The glass transition temperature also decreased from 76.45 °C to 74.32 °C (p < 0.05). A total of 88 volatile organic compound (VOC) fingerprints were identified using headspace gas chromatography-ion mobility spectrometry (HS-GC-IMS), contributing 93.6% to the principal component analysis (PCA). Analysis through scanning electron microscopy (SEM) further highlighted a more uniform and dense microstructure. This research demonstrated the feasibility of fabricating high-quality EO-fortified set yogurt.PMID:41788679 | PMC:PMC12956710 | DOI:10.3389/fnut.2026.1754468
