中文摘要:

      粮食种植、加工和储运过程易受真菌毒素污染, 严重威胁人畜健康。然而, 目前传统的真菌毒素检测方法存在过程繁琐、时效性差或灵敏度低等缺点, 难以满足现场快速准确检测的需要, 日益成为制约粮食质量安全的瓶颈。现代无损检测技术作为一种新兴的检测技术, 可以在不破坏样品的情况下对其进行质量评价, 是粮食品质在线、实时检测的一个重要发展方向, 在粮食真菌毒素污染的快速分析方面具有巨大的应用潜力。本文重点综述了近红外光谱、高光谱图像、电子鼻等典型无损检测技术在粮食真菌毒素污染检测分析中的最新研究进展, 讨论了各种技术的优点及限制因素, 并对其应用前景进行了展望。

英文摘要:

      Grain is vulnerable to mycotoxin contamination during planting, processing, storage and transportation, which causes a serious threat to human and animal health. However, current traditional methods for mycotoxin detection are usually laboratory-intensive, time-consuming or with low sensitivity, and could not fulfill the need for on site rapid and accurate testing, emerging as a bottleneck for grain quality and safety. Modern non-destructive determination methods, as a new piece of technology, can provide the quality evaluation of grain without destroying the samples. It becomes an important development direction for on-line and real-time detection of grain quality. It also has a great potential in rapid inspection of mycotoxin contamination in grain. This paper reviewed in detail the recent research progress in detection of mycotoxin contamination in grain by near-infrared spectroscopy, hyperspectral imaging and electronic nose techniques. Advantages as well as limitations of various techniques were discussed and application prospect was also forcasted finally.
