Abstract

This paper presents a novel application of terahertz (THz) sensing to monitor the quality of fruits by detecting the moisture content (MC) and the transmission response. The preliminary results show that the difference of loss in MC value from day 1 to day 3 is only 15% for pear slice, while that is 62% for apple slice, which causes the significant difference in the transmission response between pear and apple slices in the first 3 days. The results indicate that the relationship between the concentration of inner substances and the path loss of the THz radiation is very close to the absorption characteristics of the samples in the THz region. The application presented here can be extended to analyze the internal dielectric properties of fruits and obtain the spectral signatures of different compositions and the biomass quality control in fruits.
