近红外光谱技术在食品微生物检测中的应用

食品微生物受环境和时间的影响等因素产生变化,幵且检测周期长,导致关系食品质量安全的微生物检测数据不能相对真实地反映食品微生物情况。近些年,近红外检测技术因其高效、无损、快捷特点,在食品微生物检测领域越来越受到重视。文章综述了近红外检测技术的原理、特点和检测过程,以及食品中产毒真菌、食源性致病菌和食品腐败菌等检测斱面的应用,以期为近红外检测技术在食品微生物检测中的应用研究提供参考,促迚食品微生物检测采用近红外迚行在线快速检测。

Application of near-infrared spectroscopy in food microorganism detection

Food microorganisms are affected by the environment, time and other factors change, and the detection period is long, leading to the food quality and safety of the microbial detection data can not reflect relatively real food microorganisms. In recent years, the near infrared (NIR) detection technology has been paid more and more attention in the field of food microorganism detection because of its high efficiency, nondestructive and rapidity. This paper reviewed the principle, characteristics and detection process of NIR detection technology, and its application in the detection of toxin producing fungi, food pathogenic bacteria and food spoilage bacteria. It is expected to provide references for the application research of NIR in food microorganism detection and promote the application of NIR in food microorganism field.
