Evaluation of shelf-life of tomatos – comparison of different evaluationmethods

摘要

In this paper, we have applied non-invasive optical methods of biospeckles for evaluation offreshenss of tomatos stored at room temperature. Biospeckles are formed when a biologicaltissue is illuminated by monochromatic light due to scattering by organelles moving within thetissue. We have employed Optical Coherence Tomography and Speckle imaging for evaluationalong with thermal camera and smell and taste sensor devices. Tomatoes were purchased from alocal supermarket and they were spaced every three days.
