In this study, headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) and principal component analysis (PCA) were used to analyze the volatile flavor compounds in brown rice flour (BRF) and brown rice noodles (BRNs) prepared by different methods. White rice flour (WRF) and white rice noodles (WRNs) were used for comparison. The results revealed significant differences in volatile flavor compounds between BRFs and BRNs, and the types of volatile flavor compound in BRF were more than WRF. Compared with WRF, aldehydes increased in the BRF produced by refilling. The primary volatile flavor compounds of brown rice flour made by crushing brown rice fully (BRF-F) were 2-acetyl-1-pyrroline, 6-methyl-5-hepten-2-one, 2-heptanone, 2,3-butanedione, 2-octanone, 2-butanone, 1-hexanol, 1-pentanol, ethanol, 2-methylbutanol, 3-methylbutanol, and 2-methylpropanol. Ethyl acetate was found in all rice flour and rice noodle samples. The contents of 2-methylpropanol, 2-hexanone, 2-methylbutanal, 3-methylbutanal, ethanol and acetone increased after processing rice flour into rice noodles, while the contents of 2-acetyl-1-pyrroline,...
