5 panellists. The change in colour (from white to completely
brown), gills exposure (from completely closed gills/intact veil to
completely exposed gills) and incidence of decay on mushrooms
were determined subjectively using a 1–5 visual rating scale by
adapting visual quality descriptors (Table 1) (Burton et al., 1987;
Bi et al., 2014). Average data was used for statistical analysis.
