Sessions were carried out in special separated booths in a
sensoryevaluation laboratory at roomtemperature. Samples of the
different treatments (control, paprika 1.5%, paprika 2.0%, tomato
paste 2.0%, and tomato paste 2.5%) were randomly coded and
cut into 4 cm long cylinders, and perpendicularly open to evaluate
interior color by a trained panel (11 judges, females, 20–23 years
old). For training, 1 h sessions were held weekly over 4 months,
using commercial products to develop descriptive terms for the
desiredmeat product attributes. A discriminative ranking test was
performed to detect absolute differences between control and
formulations with paprika or tomato paste. The sensory ballots
prompted judges to order the series of coded samples according
to color increase (1 Pale, 5 Dark). From the ballots, the rank sums
were calculated and the absolute difference between the rank
sums was determined according to Friedman’s test
