Temperature compensation for near infrared reflectance measurement of apple fruit soluble solids contents
A Peirs, N Scheerlinck, BM Nicolaı̈ - Postharvest Biology and Technology, 2003 - Elsevier
Near infrared reflectance (NIR) spectroscopy has been used successfully to measure
soluble solids in apple fruit. However, for practical implementation, the technique needs to
be able to compensate for fruit temperature fluctuations, as it was observed that the sample
temperature affects the near infrared reflectance spectrum in a non-linear way. Temperature
fluctuations may occur in practice because of varying weather conditions or improper
conditioning of the fruit immediately after harvest. Two techniques were found well suited to …
