For consumer sensory analysis, overall liking was positively impacted
by the addition of NFE, as TRTs 2, 3, and 4 were rated higher
(Pb0.05) than C (Table 8). In addition, TRTs 1 and 2 were found to
be saltier (Pb0.05) than C. Yet, TRTs 3 and 4, having 20% and 30% reductions
of NaCl were not found different (P>0.05) for saltiness
when compared to C, suggesting a salt-enhancing occurrence
(Table 8). Overall liking and saltiness ratings suggest that NFE may
even have greater potential as a sodium reduction ingredient than another
umami-containing ingredient, soy sauce. A similar research
study conducted by McGough et al. (in press) reported a frankfurter
TRT containing soy sauce, and providing a 30% reduction in total
NaCl, was rated less salty and was also not found different for overall
liking by a consumer sensory panel than a control containing 2.5%
NaCl. These results are further supported by a study conducted by
Kremer et al. (2009), who discovered that the inclusion of soy sauce
in salad dressings, tomato soup, and stir-fried pork could allow for a
50%, 17%, and 29% reduction in NaCl, respectively. Results from the
sensory panels in the present study are also in agreement with
