A mild solar drying process on melon slices was carried out. During the whole process, Near InfraRed (NIR) spectra (900–1700 nm) were collected continuously in reflectance mode using a portable spectrometer (Viavi Solutions). Samplings were performed for the determination of weight, moisture content (MC), water activity (aw) and colour. Partial least square (PLS) regressions showed good prediction ability for MC, aw and colour parameters: MC: R2CV = 0.99; RMSECV = 2.49%; aw: R2CV = 0.97; RMSECV = 0.03; a*: R2CV = 0.91; RMSECV = 1.13; b*: R2CV = 0.86; RMSECV = 2.49; C*: R2CV = 0.87; RMSECV = 2.52; total colour difference: R2CV = 0.85; RMSECV = 1.77; Browning Index: R2CV = 0.86; RMSECV = 11.00. Ratio Performance in Deviation values higher than 3 for MC and aw models allowed their use for the estimation of such parameters' pattern along the process, providing satisfactory predictions. These preliminary data suggested the potential applicability of NIR spectroscopy in monitoring the dehydration process. [ABSTRACT FROM AUTHOR] |
