In this study, glass transition temperatures (Tg) as well as
ice crystallization and melting temperatures and enthalpy values were
determined by using Differential Scanning Calorimetry (DSC) for chicken breast
meat samples blended with different levels (2, 4, and 8%) of xanthan gum, κ-carrageenan
and gum arabic. The water activity (aw) values, moisture contents
and unfreezable water fractions of the samples were also analyzed. While the
moisture contents decreased and unfreezable moisture fractions increased, the aw
values of the samples unchanged by addition of the biopolymers. The ice
crystallization enthalpies and melting temperatures and enthalpy values
decreased with increased levels of biopolymer additions. Tg value of
the chicken breast meat was detected as -17.08±0.04°C
(midpoint). It was observed that Tg values of the samples significantly
affected by the biopolymer addition (P<0.01) and increased for the samples
including 4% and %8 xanthan gum and 8% κ-carrageenan.
