Gas chromatographyion mobility spectrometry (GC-IMS) is an emerging analytical technique that combines the separation capability of gas chromatography with the sensitivity and selectivity of ion mobility spectrometry. This review provides a comprehensive overview of the application of GC-IMS technology in the field of grain and oil processing, highlighting its role in volatile compound analysis, quality assessment, contamination detection, and process optimization. GC-IMS has been widely used to identify and quantify volatile compounds, to develop flavor fingerprints, and to assess the freshness and spoilage of various grains and oils. It has also proven effective in detecting fungal contamination and adulteration, as well as in evaluating the impact of different processing and storage conditions on product quality. Compared with traditional methods such as GC-MS and electronic nose (E-nose), GC-IMS offers several advantages, including rapid analysis, high sensitivity, and non-destructive detection. However, challenges remain regarding data interpretation and the development of standardized protocols. Future research should focus on addressing these limitations and exploring new applications of GC-IMS in the food industry. This review aims to summarize the current state of GC-IMS technology in grain and oil processing and to provide insights into its potential for future development.
