Nowadays, the issue of food safety has become the focus of the whole society. So we need to establish an efficient, accurate and non-destructive detection technology of food safety as soon as possible. Terahertz wave ranges between microwaves and the infrared light in the electromagnetic spectrum, which has a very important research value and a good application prospect. As a new detection technology, Terahertz time-domain spectroscopy can meet the needs of non-destructive detection of food safety. In this paper, we use THz-TDS technology to measure and analyze the THz spectra of flour brightener. By measuring and analyzing the pure substances and mixtures of flour and brightener, we preliminary prove that THz technology can be used in qualitative and quantitative detection and analyzing of flour quality. |
