Currently, modified potato and tapioca starches are used as functional
additives in formulating reduced-and low-fat frankfurters. However, c
orn-starches may serve as alternative sources for comminuted meat syst
ems. Meat batters formulated with ground turkey, 2% sodium chloride, 2
5% distilled-deionized water (ice), and 4% starch, including acid-thin
ned dent corn (ATDC), cross-linked waxy maize (XLWM), cross-linked den
t corn (XLDC), modified potato (MP), acid-thinned dent corn (XDLC), xa
nthan gum (ATDCG), or modified tapioca (MT) were compared. Thermal and
structural properties of the batters were evaluated using differentia
l scanning calorimetry (DSC) and dynamic rheological testing. Cooking
loss, reheating loss, and texture profile analysis (TPA) were determin
ed for cooked turkey batters. The DSC peak temperatures ranged from 57
.5 to 74.9 C, which correlated positively to onset temperatures of the
storage moduli (G') for XLWM starch. Incorporation of XLWM, XLDC, MT,
or MP starch into turkey batters resulted in significant reductions i
n cooking and reheating losses. The TPA results showed that 9.42, 8.57
, and 8.48 kg of force were required for 75% compression of cooked bat
ter segments containing MP, XLDC, and XLWM starches, respectively. Seg
ments prepared with ATDCG starch were the least firm and most springy
of all starch-containing segments.
