Interaction between carrot root dimensions and puncture force
University of Novi Sad, Faculty of Agriculture
Integrated and organics fruit and vegetable products drying by combined technology (MESTD - 31058)

The aim of this research was to determine quantitatively carrot root mass and dimensions depending on the cultivation type (flat ground and ridge), as well as to determine the differences in the root texture by measuring the puncture force in xylem and phloem. Due to higher coefficient of variation and statistically significantly higher values of maximum diameter and xylem diameter, lower quality of carrot root dimensions was determined on flat ground. Puncture force measuring was conducted by TMS-PRO instrument (Food technology) having the cylindrical punch diameter of 6 mm. Statistically significant differences in the puncture force between xylem and phloem were determined for maximum and average values of puncture force, as well as for the slope of puncture curve, for both types of cultivation. No significant differences in the yield point were determined between xylem and phloem. By testing the dependence between carrot root shape and mass, with regard to the puncture force, the highest interdependence was determined by coefficient of simple regression for critical puncture points in phloem.
