Rapid spectroscopic method to assess moisture content in free and packaged oregano (Origanum vulgare L.)
A spectroscopic study on oregano has been performed in order to find optical parameters that could be related to moisture content. Reflectance spectra have been obtained varying excitation wavelengths from the visible to the near infrared (NIR) regions of the electromagnetic spectrum. The latter reg...
