Physicochemical and sensory properties of chicken nuggets extended with
flours processed from
fermented cowpeas (FCF) and fermented partially defatted peanuts
(FPDPF) were investigated.
Addition of FCF or FPDPF decreased moisture loss and fat gain.
Reductions in protein content of
nuggets were 20.2% and 15.8% when, respectively, 20% FCF and 20%
FPDPF were added.
Regardless of level of FPDPF, nuggets required relatively lower
force and energy to shear compared
to control nuggets and nuggets extended with FCF. Nuggets extended
with FCF and/or FPDPF
had higher a* and lower L*, b*, and
hue angle values compared to the control. Color of
nuggets
containing a mixture of 2.5% FCF and 2.5% FPDPF was similar to the
control. Addition of 20%
FCF or FPDPF caused flavor of nuggets to be unacceptable. The
flavor, texture, and overall liking
of nuggets containing 5% flour (2.5% FCF and 2.5% FPDPF) were as
acceptable as the control nugget.
Results from this study indicate that FCF and FPDPF have potential
as extenders in meat systems.
