The variability of mechanical properties of the kohlrabi stalk parenchyma

The paper presents the results of the impact of kohlrabi parenchyma sampling site on textural properties. Selected texture parameters, i.e. hardness, springinees, cohesiveness and chewiness were determined by the double compression test TPA. The study was conducted on samples taken from well-defined kohlrabi layers (upper layer, middle layer, lower layer) and zones (A, B, C), because the vegetable's structure is heterogeneous. The samples were compressedat the longitudinal and transverse orientation of the fibers relative to the movement of the working tool. The results were statistically analyzed using the program Statistica 8.0. The research has shown that the place of sampling and orientation of the fibers have a significant impact on the value of all the kohlrabi texture parameters.
