The Development of Infrared Microspectroscopy (IMS) and Its Applications in Agricultural and Aquatic Products

Abstract

Infrared microspectroscopy (IMS) has undergone rapid development in the last 20 years. New infrared sources and detectors have promoted this development. More meaningful information can be achieved in less time, and spatial resolution is only several micrometers. The improved IMS is important in biology, medical science, and biochemistry. This review describes the progress of IMS in light sources and detectors, including thermal sources, synchrotron infrared sources, multiple synchrotron beams, single element detectors, as well as focal plane array (FPA) detectors. In addition, applications of IMS on agricultural and aquatic products such as cereal seeds, milk, fish, meat, forage grass, juice, and cheese are explored. Finally, new trends in the development of IMS and its importance in the fundamental and applied research of agricultural and aquatic products are discussed.
