Whiteness and shelf-life of mushrooms
During the shelf-life of mushrooms, browning does not occur
homogeneously on the surface of the slice, but some areas turn
darker than others. Therefore, a single slice cannot be characterized
by a single colour, but by the average colour of several points on the
same surface. This is sometimes performed by measuring the
colour on 10e20 different spots on the surface using a chroma
meter. Besides, the thorough characterization of the mushrooms
freshness involves performing several replicates, due to the
inherent variance between different slices of mushrooms. At this
point, the authors considered the advantages of using a commercial
scanner to record the image of several slices at the same time and,
later, process the image using the appropriate software. Several
authors have used this technique to characterize food products,
showing comprehensive, accurate and reproducible scientific data
