The textural attributes of the control and bleached tomato pomaceadded
meat-free sausages are also shown in Table 5. The hardness, cohesiveness,
chewiness and adhesiveness values of cooked meat-free
emulsions containing tomato pomace (up to 5%, w/w) had significant
differences (p b 0.05) with control samples. Interestingly, the samples
with 7% tomato pomace (V7) had the values similar to control sausages.
The decrease in hardness and cohesiveness of the V7 sample is probably due to the negative effect of tomato pomace compositions on the
emulsification ability of the formulation contributing to a greater loss
of liquid during compression in the TPA test. In this sense, insoluble
fiber of tomato pomace could prevent the absorption of oil by soy
protein isolate system, leading to lower hardness and cohesiveness.
