The texture of the fresh and osmotically dehydrated samples
was determined by evaluating (10 replicates) stress at rupture in
a Universal texturometer (TA-XT2i Texture Analyser, Stable Micro
System, Surrey, UK.). The method used was to measure the force
in compression at the moment of rupture. This uniaxial compression
test was carried out at a compression speed of 5 mm/s and
60% sample deformation. The stress at failure was determined from
the peak of the stress–strain curve (Pereira et al., 2006).
