Abstract

The rheological constants of the four element Burgers model when potatoes (Diamont and Santana) were subjected to various fixed loads (stresses) on the main dimensions of the tubers were investigated .The rheological constants were K₁(instantaneous elasticity ,N/mm)-K₂(retarded elasticity ,N/mm)-C₁(free viscous element ,N. min/mm and C₂(retarded viscous element ,N. min/mm).The investigation was conducted for fresh and cured tubers as well as tubers under two different storage systems (trditional Nawalla at 16+3^oC ; 84% RH and Cold store at 4^oC ; 90% RH ).

Main Subjects
