Colour a parameter was modified by the salts. NaCl
alone produced a reduction of a values, meanwhile STPP
plus NaCl recovered partially the values of this parameter
in comparison to non-treated samples. Therefore, the previous
recommended concentrations of STPP and NaCl
did not alter substantially the colour of the sous vide
cooked samples.
It is apparent that under the present experimental conditions,
precisely at temperatures of 60–65 C, the formation
of a stable gel has occurred. Under these conditions the gel
structure was able to entrap water, reducing in consequence
CL.
