Selection of efficient wavelengths in NIR spectrum for determination of dry matter in kiwi fruit

The feasibility of using efficient wavelengths in the near-infrared (NIR) spectrum for the rapid determination of the dry matter (DM) in kiwi fruit was investigated. Partial least squares (PLS), synergy nterval PLS (siPLS) and genetic algorithm siPLS (GA-siPLS) were comparatively performed to calibr...

Chaitep S. The feasibility of using efficient wavelengths in the near-infrared (NIR) spectrum for the rapid determination of the dry matter (DM) in kiwi fruit was investigated. Partial least squares (PLS), synergy nterval PLS (siPLS) and genetic algorithm siPLS (GA-siPLS) were comparatively performed to calibrate regression models.
