中文摘要:

      作为一种新兴的检测分析技术，气相离子迁移谱兼备气相色谱的高效分离能力和离子迁移谱的快速响应能力。因检测速度快、用时短、数据可视化等优势，在食品领域中得以广泛应用，特别是在食品等级分类、掺假检测、食品新鲜度评价、食品加工过程品质监测与贮藏期间变化方面。玉米、小麦、大米、大麦、高粱、糙米等谷物是我国重要的经济作物，不仅提供机体所需的营养素和能量，同时作为重要的传统美食加工原料，在日常生活中需求量大。随着人们对于健康营养食品的消费意识增加，围绕谷物及其制品的研究成为了关注的热点。基于此，本文介绍了气相离子迁移谱的原理及特点，并系统整理了该技术在谷物食品产地溯源、香气成分分析、原料精深加工等方面的研究情况，旨在为谷物资源的开发利用和品质调控提供重要支撑。

英文摘要:

      As an emerging detection and analysis technology, gas chromatography-ion mobility spectrometry combines the high separation efficiency of gas chromatography and the fast response capability of ion mobility spectrometry. Due to the advantages of fast detection speed, short time and data visualisation, it has been widely used in the food field, especially in food grade classification, adulteration detection, food freshness evaluation, food processing quality monitoring and changes during storage. Corn, wheat, rice, barley, sorghum, brown rice and other cereals are important economic crops in China, which not only provide nutrients and energy needed by the body, but also are important raw materials for traditional food processing, and are in great demand in daily life. As people’s awareness of healthy and nutritious food consumption increases, research around grains and their products has become a hot spot of attention. Based on this, this paper introduced the principle and characteristics of gas chromatography-ion mobility spectrometry, and systematically compiled the research of this technology in the traceability of cereal food origin, analysis of aroma components, and deep processing of raw materials, aiming to provide important support for the development and utilisation of cereal resources and quality regulation.
