Human existence depends on receiving energy which is required for its body life and it is achieved by agriculture products and manufactured food. Supplying sufficient and qualified agricultural products require high-tech instrumentation and applying of appropriate tools which are adequate/reliable, fast, and non-destructive.
Spectrometry, as a recent procedure of measurement and instrumentation, has found a venerable value in sciences, especially in agriculture and food industries. Field monitoring and quality control are the most important practices that are reported to be done by spectrometry methods. In this paper, some of these applications are reviewed. Finally, spectrometry, as a non-invasive, fast, and non-contact method of food monitoring, is suggested to agricultural specialists.
