The detection of agricultural products and food using terahertz spectroscopy: A review

摘要

Demand for high levels of quality and safety in agricultural products and food requires appropriate analytical techniques for analysis both during and after production. Desirable techniques should be quick, easy, and safe to use; require minimal or no sample preparation; avoid sample destruction; and be accurate. In this study, the recent technical applications of terahertz spectroscopy to identify and classify, qualitatively and quantitatively analyze, evaluate, and safely control agricultural products and food are reviewed. The challenges and future outlook of terahertz spectroscopy are discussed.
