Texture or toughening was determined by taking nine spears
from each tray. The texture of each sample was measured at the
middle point of each spear section by performing a cutting test
with a texture analyzer (TA-XT plus, Stable Microsystems) a
method which was modified from Rodríguez et al. (2004). Values
are expressed as maximum shear force (N) using a single blade
(7
12 cm) that cut each sample at a cross-head speed of
2.0 mm s1 over 12 mm.
