of 7 assessors, aged 35–58 years, following a procedure adopted
from the international standard (ISO 8586-1, 1993) in a sensory
laboratory equipped with daylight and fulfilling the requirements
set by ASTM (ASTM 913, 1986). Raw and boiled samples, in portions
of 20 g, were evaluated on two consecutive days on the colour
attributes whiteness and browning.
