Consumer sensory analysis responses for NFE containing frankfurters
are found in Table 5. Overall liking was impacted by the addition
of NFE, as all TRTs were liked more (Pb0.05) than C. Further, all
TRTs containing NFE were perceived as saltier (Pb0.05) than C, with
trends showing saltiness ratings increased as the amount of added
NFE also increased even though no differences in NaCl levels existed
(Table 3) The sensory saltiness results indicate that the inclusion of
NFE allows for an increase in the perceived salty taste. These results
are in agreement with those found by Kremer et al. (2009), as they
discovered that inclusion of soy sauce, another umami-possessing ingredient,
in salad dressings, tomato soup, and stir-fried pork could
lead to an increase in salty taste. The increase in perceived saltiness
caused by the inclusion of NFE in this study further supports that
umami-substances, such as NFE, can offer an increase in perceived
saltiness (Fuke & Ueda, 1996; Keast & Breslin, 2002). Overall taste intensity
was also increased by the addition of NFE, as all TRTs rated
higher (Pb0.05) for taste intensity than C. The taste intensity results
