Color of apple wedges was measured on both sides of each
wedge using a tri-stimulus CR-400 Minolta Chromo Meter (Minolta
Co. Ltd, Japan) on days 0,1, 3, 7 and 14 of storage. The Chroma meter
was calibrated with a standard white plate (Y¼ 94.00, x¼ 0.3158,
y¼0.3322). The values reported are the means of 10 lightness (L*)
values.
