In this paper, we have applied non-invasive optical methods of biospeckles for evaluation of freshenss of tomatos stored at room temperature. Biospeckles are formed when a biological tissue is illuminated by monochromatic light due to scattering by organelles moving within the tissue. We have employed Optical Coherence Tomography and Speckle imaging for evaluation along with thermal camera and smell and taste sensor devices.
