Furthermore, as previously discussed, tomato pomace
contains a large amount of polysaccharides such as fiber and pectin.
The pectin could contribute to an increase in work of shearing value,
while cellulose and lignin could affect hardness and cohesiveness of
frankfurter (Calvo et al., 2008). Thus, the increase in hardness of beef
frankfurter containing tomato pomace could be related to the presence
of fiber (39.1%) and some hydrocolloids (lignin and cellulose) in the
tomato pomace. Moreover, a lower lipid content of cooked emulsion
containing tomato pomace (Table 2) compromises the emulsification
ability of the emulsion, leading to a decrease in cohesiveness as explained
by Crehan, Hughes, Troy, and Buckley (2000).
