近红外光谱技术在甘薯品质检测方面的应用研究进展

Recent Advances in the Application of Near-Infrared Spectroscopy in Quality Detection of Sweet Potato

甘薯是一种药食兼用且低热量的块根状食物,其富含多种人体必需的营养物质和生物活性成分,可用于预防多种疾病。甘薯品质的优劣直接影响其产品质量、分类分级及经济价值。快速、高效的检测技术在保障甘薯品质和安全方面可发挥重要作用。基于近红外光谱(near-infrared spectroscopy,NIRS)技术快速检测分析甘薯品质的研究已有不少报道。本文全面综述了NIRS技术在甘薯理化组分(蛋白质、淀粉、糖类、水分等)、活性成分(黄酮类物质、类胡萝卜素等)、制品掺假以及其他(品种鉴定、重金属、微生物污染等)等方面的研究及应用进展,同时提出了NIRS技术在甘薯品质检测应用方面的发展趋势和研究重点,以期为进一步完善NIRS在甘薯品质快速评价研究和相关快检设备研发方面提供更多借鉴。

Sweet potato is a kind of low-calorie root food that has also been used for medicinal purpose.It is rich in a variety of essential nutrients and bioactive ingredients for the human body,and can be used to prevent various diseases.The quality of sweet potato directly affects its product quality,classification and quality grading and economic value.Rapid and efficient detection technologies play an important role in ensuring the quality and safety of sweet potato.Many studies on the rapid detection and analysis of sweet potato quality based on near-infrared spectroscopy(NIRS)have been reported.This paper comprehensively summarizes recent progress in the application of NIRS in the detection of the general chemical components(protein,starch,sugar,and water),active components(flavonoids and carotenoids),adulterants,heavy metals and microbial contamination in sweet potato as well as in its varietal identification.Moreover,this paper proposes future trends and research priorities for the application of NIRS in the quality detection of sweet potato.This review is expected to provide more references for further improvement of rapid quality assessment of sweet potato by NIRS and for the development of related fast testing equipment.
