Effects of different thermal processing methods (Ohmic heating, high and low power, microwave and
conventional heating) on textural properties of cylindrical pieces of root vegetables of carrot, red beet
and golden carrot were investigated and compared with conventional and microwave processes. The
samples were subjected to different processing methods and textural parameters of the processed samples
were analyzed using texture profile analysis (TPA) at different processing times. Texture parametersprocessing
time data were fitted into a previously suggested equation and texture softening rate (K) and
residual constant (A) values were calculated. From the K and A values it can be concluded that not only
Ohmic heating resulted in greater softening rates but also the final hardness of the samples treated by
Ohmic heating was significantly lower than those of other samples treated by either conventional or
microwave methods. Negative correlations were found between texture hardness and weight loss of
all samples undergone different processing methods.
