Sensory evaluation and Gas-Chromatography Ion-Mobility Spectrometry(GC-IMS)were used to analyze the flavor characteristics and volatile organic compounds(VOCs)of chilli oil prepared at different oil temperatures.The sensory evaluation results revealed that the aroma of chilli oil prepared at different oil temperatures(120,140,160,180,200 ℃) was significantly different,but the color and taste were not significantly different;45 species of VOCs in chilli oil were identified by GC-IMS,mainly including aldehydes,ketones and terpenes.Oil temperatur...
