Methods used for identification of species of origin of
raw meat include sensory analysis, anatomical
differences, histological differentiation of the hair that
may possibly exist in the meat, properties of tissue fat,
and level of glycogen in muscle tissue, as well as
electrophoresis and DNA hybridization (1-4). Most of
these methods have been reported to have limitations in
use due to problems in specificity (i.e. sensory analysis,
glycogen level, histological differentiation, properties of
tissue fat, and immunological methods), complexity (i.e.
electrophoresis and DNA hybridization), high cost (i.e.
DNA hybridization), and some requirements for baseline data about the differences in protein compositions (i.e.
isoelectrofocusing) (5-7). There is a need for the
development of a more accurate, fast, and easy-to-use
method due to the limitations of the existing methods
mentioned above (5).
