The aim of the study was to determine the effect of whole milk powder (WMP) as
heterologous proteins on chicken breast emulsion-type sausages. The quality
properties of WMP on such chicken breast emulsion-type sausages were
investigated by measuring the proximate composition, pH, color, cooking yield,
protein solubility, and by applying other methods, such as texture profile
analysis (TPA), microphotograph, sodium dodecyl sulfate-polyacrylamide gel
electrophoresis (SDS-PAGE), and electronic nose. The crude fat, protein, and ash
contents of 15% WMP samples were significantly higher than the control samples
(
p
< 0.05). The redness of the cooked samples
significantly increased with an increase in the WMP contents (
p
< 0.05). The cooking yield of WMP treated samples was significantly
higher than the control sample (
p
< 0.05). Additionally,
the hardness, gumminess, and chewiness of WMP treated samples were significantly
higher than the control sample (
p
< 0.05). The
sarcoplasmic and myofibrillar proteins of samples containing 15% WMP were
significantly higher than the control samples (
p
<
0.05). The result of SDS-PAGE showed that the C protein, sarcoplasmic protein,
actin, and tropomyosin increased with an increase in the WMP contents. The
principal component analysis plot of WMP-treated samples was clearly different
from that of the control samples. Based on these results, it was predicted that
WMP could be useful as heterologous protein on emulsion-type sausage.
