Considering that appearance of white button
mushroom (WBM) as the trigger for registering its quality,
this study was aimed at analyzing the visual cues by the
application of image processing tools. While L-a-b colour
space and skewness was used for estimating chromatic and
morphological characteristics; onset of discolouration of
WBM was predicted by hyperspectral image analysis.
Undamaged (UD) and damaged (D) mushrooms were
stored under refrigerated conditions (3–5 C and 90% Rh).
RGB and hyperspectral images were acquired on alternate
storage days 1, 3, 5, 7 and 9. Weight loss, texture and
moisture content of stored mushrooms were also recorded
during the storage period. Colour changes in stored UD and
D were found to be in b (21.55) and a (2399) value,
respectively. Browning index in D was 83–212% higher
than UD mushrooms across the storage period. Weight and
firmness losses in D were higher by 65.9 and 31.4%,
respectively than UD. Morphological characteristic in
terms of aspect ratio and roundness were not found to vary
significantly over the storage period for both UD and D
mushrooms. Chemometrics revealed that multiplicative
scatter correction was the best pre-processing tool and that
onset on discolouration is conspicuous in the spectral
region of 520–800 nm. k-NN fared better than PLS-DA for
correct classification (100%) of UD and D mushrooms.
