Moiseev and Cornforth (1997) studied the effect of
NaOH and STPP on bind strength and sensory characteristic
of restructured beef rolls. Various levels of added
water (0, 5 and 10%) and three types of ingredients were
used: (i) 1% NaCl (control); (ii) 1%NaCl + 0.375% STTP
and (iii) 1% NaCl + 0.07% NaOH. The results show that
with either 5 or 10% added water, there were no differences
in the juiciness of NaOH and STPP rolls, but both
were juicier than controls. However, STPP rolls with 20%
added water had higher juiciness score than either
NaOH rolls or controls. The overall acceptability of STPP
rolls was higher than NaOH rolls at 5 and 20% added
water, but at 10% added water there was no significant
difference in the acceptability of NaOH and STPP rolls.
The strength of water-binding and cooked yield of samples
was improved as follows: STPP > NaOH > control.
These results confirm that STTP did not only increase
the pH value but also strongly increased the extraction of
protein in meat.
