3.2. Texture
The textural properties of the meat emulsions were evaluated by
three parameters (Table 1): Stress (N), Young's modulus (MPa), and
strain (%). Stress represents the force needed to break the meat
emulsion, and is a measure of firmness/hardness. Strain represents
the distance in percentage where the probe needs to travel through
the meat emulsion before it breaks, and is a measure of crispiness/
crumbliness. Young's modulus represents the slope determined as
force per strain and is a measure of stiffness. Both stress and strain
were found to be significantly higher in meat emulsions added TG as
compared to the control meat emulsion (Table 1). The effect of green
tea extract on the textural properties of themeatemulsionswas less apparent.
However, the stress of meat emulsion added 1500 ppm green
tea extract was significantly lower as compared to the control meat
emulsion, and both strain and stress tended to be reduced by addition
of increasing concentrations of green tea extract.
